Engine problems from spain

[santi]

We need help. We hava changed the full pump. fuel filter,
impeller, spark plugs.Oli levels are perfect.In Spain don´t have service.

We don´t find the problem.
Does anyone have conecctión check and software for the engine??.
Where can i buy the conecction check and software?
Indmar 5.7l 325 hp.The boat has 330 hours.

Thanks.

[Arek]

Hi guys, It's my firends boat. We would really apreciate any help on this.
I think we've tried it all by now.
For some reason the boat jumps in the "limp mode" and we can`t find out why.

Any suggestions?

[superfet]

Hi there.
I get the same problem if i use the cruisecontrol and don´t turn it off after stoping. Check if cruise control is on and turn it off.

[KSmith]

Tell us more about the boat like Year and Model, does it have Moomba Crusie, Perfect Pass? Has it ever run properly for you or is this a new problem?

As superfet noted Moomba Cruise can cause the engine to behave as you descibe if it has been left on after the engine has been turned off.

[newty]

Take a look at your oil level transmission level. That will put your boat into limp mode. Also sheck your impellar. You should be running around 140F. Looks like you were getting higher than that.

140??? im usually around 160, 140 seems wayyy cold

[jmb]

I am at 160/170

[mmandley]

Engine water temp also has to do with your location, here in the NW where water is 60 all the time it will run cooler then in TX and AL where the water is in the mid 80s to 90s

[Hoopskier]

To me it looked like the cruise switch was in the "on" position.

[santi]

Arek, Thanks a lot.

Superfet, the problem occurs with the Moomba Cruise on and off.
It hasn´t Perfect Pass.

KSmith, the first time was in the summer of 2009, only one fault and
we didn´t give its importance.
2010, at 10 hours a session occured twice and three times
with food and beer whem it occurred the fault.
A day didn´t fail and the next day the problem was constant.
In summer of 2011 we changed the fuel pump.
I was well the first 4 hours after failure, this video is
from october 2011.

Newty, the impeller has been changed before and after the problem.
Here in Madrid, usually 140 at 160F. All Oli levels are perfect.

Hoopskier, the moomba cruise was in the “on” position and “off” position.

[wolfeman131]

with food and beer whem it occurred the fault.

There it is!

Must've been some bad beer on the boat and you upset the Gods!

[KSmith]

Santi, What is the Year and Model of the boat?

So this has been happening on and off for a couple of years then?

One member had this issue, it was intermittent for him as well and he said fixed it. He said he found some
wires on back of engine rubbed through the insulation and were shorting on engine near the control module.

He had a 05 LS so when he says back of engine that would be the front in a V drive configuration. Look around the engine and see if there are any wires that worn through the insulation and could be shorting.

[Arek]

It's a beautiful 2008 outback with a 5.7 assault motor in one of the bests spots in the sunny Spain.

[Arek]

Tranny level ok. Oil level ok. All the mantainence done. All the wires checked. Tranny oil cooler checked, no debris. Fuel pump and filter new. No water in tank. Gas filter new. All senders seem to be ok. Is there any way to check them with no ODB reader?

[KSmith]

Well it seems we have exhausted all the typical suspects. Is there no way to get the boat to a auto parts store that has an ODB reader you can use? Say the Spanish version of AutoZone?

[newty]

Maybe try unplugging the Moomba Cruse from the ECU and see if that helps.

[DOCDRS]

Not ODB II readable. These are MEFI controlled (marine electronic fuel injection version V ). You need a special Indmar connector and software which you can get from Rinda technologies. Soon I'm going to get one of these. They are around 5-600.

[DOCDRS]

Techno impaired as in Wakeboardn cap o world on vac w family. Sounds like prob is intermittant but your ecm is getting info from a sensor or lack of info that sends it into limp mode. Could be a bad ground or connection that hits once things heat up or a bad sensor prob the former I would check all the wires from the temp sensors and get a schematic from Indmar. Also get a Mefi reader as looks like your on your own over there. I have not seen the you tube vid as I am on my phone. Just my .02

I'm assuming, among other things, this equipment reads an on board computer which actually monitors the sensors and retains the readings in memory. Think I'm on the right track here. If it's a sensor or wiring issue, couldn't one use a volt ohm meter to take the readings? A little more time consuming and more legwork required (looking up sensor specifications).

A cheap mans troubleshooting tool but it might help the guy out in Spain. I don't suspect anyone there would have this equipment and software. Even if he orders it, could take a while to get there.

a digital multimeter would do the trick, call indmar and speak to a tech there , they are very helpful and will probably send email you a wiring diagram maybe even sensor resistance values if they have them They are very helpful www.indmar.com

[Arek]

Thank you very "mucho"! We are looking for a mefi connector over here. There are loads of volvo and mercruiser official garages maybe they could help us. We wll also contact Indmar. The Spanish Moomba importer says that when he connected the software no problem came up. He also says that there is no "memory" as such, that he has to run the diag when the problem is happening. It doesn't make much sense to us...
What sensors could activate the limp mode?
Temp
Oil pressure
Tranny oil pressure
Water temp
???

Not all mechanics are up to snuff. Are they indmar certified? with a valid certificate? Call indmar and ask your questions. I would think water temp sensor and oil pressure would be 2 good ones . Which motor specifically do you have 340 cat? 325 mpfi? it always helps if you list it in your signature with boat model and year.

[rsinger]

Just remembered. Look below to see if any of this might help. I had some electrical issues last year.

https://forum.moomba.com/showthread.php?16621-Injector-fuse-blowing

Look for the post by Engine Nut. There's a link to some schematics.

[santi]

Thank you very much to all for your helps.

Within a month, starts the season in spain, heat returns and good weather.

And I want to have the boat managed to date.

I will return to Check all wiring and temperatures will look.

I'll get in touch with Indmar to watch the video.

I will talk about how to the problend end.

Thanks a lot.

[Arek]

While Indmar answers our email, we are checking the procedure to read the ECM ourselfs.
http://www.rinda.com/acro/techmate_manual_v6.pdf
Here it says that the PCMs are equipped with Fault History, but it doesn't mention any Fault History for the GM Mefi5 Ecu.
Can that be right?

[santi]

This is the problem....

[Stazi]

I would look at the throttle position sensor. It's throwing a fault.

[santi]

stazi, where is the throttle position sensor? How do you change?
Somebody see something in the Parameter Description Value with faulted?.

Thanks DOCDRS.

[Arek]

Santi, hold on a minute.

Before we order a new TPS, you need to check the reading again.
Have you noticed this?

Fuel Pressure 147,9 PSI !!!!!!!!!!!!!!
The correct fuel pressure must be 60PSI !

Santi, espera un momento,
Antes de pedir un TPS nuevo, deberías volver a conectar el lector.
Has visto esto?

Presion de Combustible 147,9 PSI !!!!!!!!!!!!!
La presión correcta debe ser 60PSI

[Arek]

I've just sent an email to Indmar, let's see what do they say.

[Stazi]

Thanks DOCDRS.
It should be right on the throttle body attached to the intake manifold it will be connected to the butterfly that opens and closes the throttle.

[papou]

Looks like the boat won't pas 1500 rpm when hot hard to tell from video.
If you have a water strainer be sure the fittings don't twist it will pull in air .

This is what happen to my LS

[santi]

Please, I am a serious person, i have a 40 years old, i only ask for help for repairs my boat.

I do not speak English.
Here in Spain, Moomba Boat buyers have no support technical.


Por favor, yo soy una persona seria, tengo 40 años, solo pido ayuda para arreglar mi barco.

Puede usted intentar abrir este fichero?

Yo no hablo ingles.

Aquí en españa los compradores de barcos Moomba no tenemos soporte técnico.

[santi]

I try to read it all but it's hard for me.
Please slow down.
Intento leerlo todo pero es complicado para mi.
Por favor , más despacio.

So it has been tested:

I need you to do another recording, this time do it in a specific manner. Turn the key on with the engine off and start recording with Diacom. After 30 seconds, (with the engine still off) move the throttle handle from the idle position slowly to the wide open throttle position then back to the idle position. The whole movement from idle to wide open throttle and back should take about 30 seconds.


Now start the engine and let it run at idle RPM for about 30 seconds. Shift the engine into gear and let it idle in gear for about 30 seconds. After 30 seconds, increase the rpm to 1000 RPM and leave it there for 30 seconds then increase the RPM to 1500 for 30 seconds. Continue this process increasing the RPM in 500 RPM increments till the engine either misbehaves or reaches wide open throttle. If the engine does misbehave and the RPM drops, do not move the throttle handle back to the idle or any lower position for at least 30 seconds. Send me a copy of that recording and I may be able to better tell what the problem is.

Thanks to recover post

[NateHaskovec]

When you turn the key "on" does the check engine light come on? Not starting the boat, just turning the key on? With the key on move the throttle stick. Does the butterfly valve move also?

[ga-lsv05]

There is a manual throttle body setup for.that intake. Could be an option

2005 mobius lsv 2900lbs ballast

[santi]

It should be right on the throttle body attached to the intake manifold it will be connected to the butterfly that opens and closes the throttle.
Thanks Stazi.

Yes, i turn the key "on" does the check engine light come on but after the light come off. I move the pedal position and the butterfly valve mode also.
Thanks NateHasKovec.

The Diacom problem give me this problem:
SPN: 65618 Electronic Throttle Control (ETC) Return Fault.
We disassemble this piece, is this?

http://img207.imageshack.us/img207/2011/tpsmoombaoutbakv.jpg

This piece is behind the pedal position (Throttle stick).
Thanks.

[lewisb13]

Sounds like you need a new throttle position sensor (tps) maybe????

[ga-lsv05]

The problem sounds to be in the throttle body. Butterfly not opening and closing properly.

2005 mobius lsv 2900lbs ballast

[Stazi]

Sounds like the Throttle Position Sensor is not working. I'm not familiar with GM TPS's, maybe someone else can identify the sensor in the picture you posted.
I found this info on this online Indmar manual:
SPN 65618
FMI 7
Fault Description: ETC Return Fault Mechanical System Not Responding or Out of Adjustment
Diagnotsic procedure:SPN 65615, 65616, or 65618 on page 9-147

ftp://ftp2.indmar.us/Manuals/Service%20Manuals/EFI%20Manuals/MEFI%206%20Service%20and%20Diagnostics.pdf

From reading the disgnostic procedure, sounds like the ELECTRIC MOTOR that moves the butterfly is the problem, not the TPS that reads it's position.

SPN 65615, 65616, or 65618
Diagnostic Instructions
• Perform the Powertrain On Board
Diagnostic (OBD) System Check on page 9-64
prior to using this diagnostic procedure.
• Review Strategy Based Diagnosis on page 6-4 for
an overview of the diagnostic approach.
• Diagnostic Procedure Instructions on page 6-5
provides an overview of each diagnostic category.
SPN Descriptors
SPN 65615 FMI 7: Electronic Throttle Control (ETC) Actuation Fault Mechanical System Not Responding or Out

SPN 65616 FMI 12: Electronic Throttle Control (ETC) Process Fault Bad Intelligent Device or Component
SPN 65618 FMI 7: Electronic Throttle Control (ETC) Return Fault Mechanical System Not Responding or Out of
Adjustment
Circuit/System Description
The engine control module (ECM) controls the throttle
valve by applying a varying voltage to the control
circuits of the throttle actuator control (TAC) motor.
The ECM monitors the duty cycle that is required to
actuate the throttle valve. The ECM monitors the throttle
position (TP) sensors 1 and 2 to determine the actual
throttle valve position.
Conditions for Running the SPN
65615–7
• Before the ECM can report that SPN 65615–7
failed, SPNs 65601, 65602, 65610, and 65618–7
must run and pass.
• SPN 630, 65580, 65620, 65621, 65622, or 65623
is not set.
• The ignition is ON, or the engine is operating.
• The minimum throttle position is learned.
• The ignition voltage is greater than 9 volts.
• SPN 65615 runs continuously when the above
conditions are met.
65616–12
• SPN 630, 65580, 65620, 65621, 65622, or 65623
is not set.
• The ignition is ON, or the engine is operating.
• SPN 65616 runs continuously when the above
conditions are met.
65618–7
• Before the ECM can report that SPN 65618–7
failed, SPNs 65601, 65602, and 65610 must
run and pass.
• SPN 630, 65580, 65620, 65621, 65622, or 65623
is not set.
• The ignition is ON, or the engine is operating.
• SPN 65618 runs continuously when the above
conditions are met.
Conditions for Setting the SPN
65615–7
The difference between the commanded and the
actual throttle position is greater than 10 percent for
greater than 276 mS.
65616–12
The predicted throttle position calculations in the main
processor differ from the motor control processor.
65618–7
The ECM detects that the throttle blade did not return
to the default position, during power up.
Action Taken When the SPN Sets
• SPN 65615, 65616, and 65618 are Type A SPNs.
• The ECM commands the TAC system to
operate in a Reduced Engine Power mode.
Conditions for Clearing the SPN
SPN 65615, 65616, and 65618 are Type A SPNs.
Diagnostic Aids
• Inspect for a condition in which the throttle valve
may have been held open. For example, ice
may have formed in the throttle bore causing the
throttle valve not to close.
• A high resistance condition on the throttle position
and throttle actuator control circuits could cause
a DTC to set.
• A low battery condition may cause a DTC to set.

[lewisb13]

His boat is not drive-by-wire. It has a throttle cable connected directly to the butterfly valve. Shouldnt be an electric motor opening and closing. So again, sounds like the position sensor.

[Stazi]

Then you must be right, but weird it's giving and ETC fault.

Why aren't any of the Indmar techs helping this poor guy out on here? I bet they could read his fault list and tell him exactly what wrong or at least tell him what specifically to check for.

[ga-lsv05]

Every indication is that it is fly by wire that would explain the throttle stick position sensor mentioned in his previous post. Would also explain the code he is getting

2005 mobius lsv 2900lbs ballast

[lewisb13]

Thats why its giving the ETC fault. The throttle % open is not matching up to what the MAF sensor is seeing for airflow. Its a safety feature so that you can't put more air in the engine than is required. So the ecm is backing off ignition and timing causing the motor not to run right because it thinks there's more air getting in the cylinders than there actually is.

[lewisb13]

Forgive me for not knowing the answer to this, but my 05LSV had a throttle cable. When I went and looked at the 13LSV at the dealer the other day it also had a cable coming out of the throttle. Are any of these boats drive by wire?

[ga-lsv05]

Just wouldn't give an etc code on a mechanical throttle body setup. Not possible unless some catastrophic software failure occurred. Push the throttle plate open with your finger and check for corrosion on the inside of the throttle body neck or debris. Also the plate should move smoothly. Etc problems are common on gm vehicle and is mostly due to dirt or debris from lack of cleaning.

2005 mobius lsv 2900lbs ballast

[ga-lsv05]

There is also a throttle relearn procedure that the fly by wire t body has to go through

2005 mobius lsv 2900lbs ballast

[Stazi]

Santi, take a lot of pictures of the throttle body, inside and out on your boat and post them here so we can see what kind of setup you have.

Hopefuylly you have a better camera to use than your last picture as it is too blurry.

En Espanol:
Santi, tomar muchas fotografías del cuerpo del acelerador, dentro y por fuera en su bote y publicarlos aquí para que podamos ver qué tipo de configuración que tienes.

Esperemos que tiene una cámara mejor de usar que su última imagen como es demasiado borrosa.

[santi]

Stazi, thanks for pdf, I knew.
Why are not any of the Indmar techs helping this poor guy out on here?.
Apparently not.
I've sent an email to Idnma with the recording of Diacom, after being fighting with the program, we have “learned to handle it”, but to this day I have not said anything. And I do not understand why not help me ....

The boat has only 360 hours .... but I will look if it has any dirt or debris.
ga-lsv05 , please do not understand this: There is Also a throttle relearn procedure that the fly by wire t body has to go through.
Can you put in other words? Thank you.

lewisb13 said, Forgive me for not knowing the answer to this.
Any help is good for me, thank you very much for answering.

Stazi, this weekend I'll go back to the lake and makes photos with a better camera or video.Thanks.

Here in Spain there are three company working with Indmar engines.

1. - World Quality Tech only Malibu Boats
2. - Magic Estadi only Mastercraft Boats.
3. - Wakextreme Moomba and Supra.
I still hope they (Wakextreme Company) comes to chekear me boats.
Two years ago I went through the first time this problem and in the end I had to buy the Diacom program and the plug, and I chekear my boat together with a car mechanic.
Here in Spain cost a lot to have a boat on a lake and I'm wasting time, money and the worst I can do wakeboarding.
Thanks a all.

[ga-lsv05]

Every symptom and corresponding codes would indicate a faulty throttle body to me. Take pictures of the throttle body for us so we can see what's going on there. Have stazi translate if need be as I don't speak Spanish

2005 mobius lsv 2900lbs ballast

[chawk610]

Hi there.
I get the same problem if i use the cruisecontrol and don´t turn it off after stoping. Check if cruise control is on and turn it off.

^^^^^ we did this when we first got the boat... makes you think all is lost! LOL

[Arek]

It's a drive by wire system. It's a 2008. Since this year the tps is attached directly to the throttle handle.

[Arek]

We checked the throttle body and it looked clean, we also opened the Etc and it looked perfect. We found the tps and the cable was bend badly, so we straightened it and moved the connections and the boat performed perfectly for the rest of the day.
Next day the boat failed again, so Santi and a car electrician disconected the tps and went through the connections. Everything connects Ok.
Next step would be order a new TPS (I guess...) . I have already contacted Skidim let's see if they have any.
Is there any way to check the TPS?

Thanks!

[lewisb13]

There is a way to check, but you probably don't have access to the software to do it. Go order a new tps and be done with it.

[Stazi]

I'm with Lewis. Get a new TPS and be done with it. Also make sure the wires that were bent have continuity to the plug. (I'm thinking this is what you did with the electrician).

If that's a GM TPS then I bet you can order it online from somewhere like Autozone for dirt cheap rather than getting raped buying it through a European dealer.

YES YES check the continuity in the wires. I would almost go do that before you buy a new TPS

I think we must check that TPS. Seems like its a part of the teleflex drive by wire throttle system and has to be changed completely.

It's the little black potentiometer and the full assembly costs 319$!

Send that exact picture to your dealer and have them figure it out.

By this I ask help Moomba USA and Indmar and everyone can help me ....

Anyone know where I can buy only the sensor and i dont buy the full assembly?
and anyone knows the manufacturer of TPS ...is really GM manufacturer???

I just want to do wake and i can not.........and time passes.

I am sorry but I'm pretty upset, I have a ship of 40,000 Euros €
and I can not enjoy it.

We need an mechanic who knows these engines Indmar.....He would win a lot of money in Spain ....

Thanks a lot lewisc13 and Stazi

Is the sensor in the pic on the throttle stick? If so I truly think you're going the wrong direction and it most certainly would not be a gm product.FWIW, I believe your problem lies in the throttle body itself as I see similar issues atleast twice a week on vehicles.

Yes I'm saying that. According to stazi's post #41, the code you have is for electronic throttle control motor not returning or out of adjustment. The throttle motor has a potentiometer in it that corresponds to inputs from the throttle stick sensor. The motor cannot match said input from the throttle sensor and goes into failsafe to avoid unintended acceleration. I would thoroughly check that throttle body for correct voltage throughout open and closing valve positions. Or just replace it
