No Throttle Control

[newyear14]

If you need a better understanding of the Throttle servo cable linkage. I believe the perfect pass manual had instructions for troubleshooting. Throttle should be on top, side of engine and another cable running around to a silver(color) plate with a knob on top. When the ignition is engaged the servo should turn to tight the cable, giving the resistance needed for the throttle to work. There is a allen screw in the knob that could also be loose if the servo is working correctly. Could prob take some pictures of this if needed.

Thanks. I am not very mechanical so if you can post pictures, it will be helpful.

I was told by the mechanic that my 09 OB V does not have a servo motor. Anyway they "flashed" the ECM and this seems to do the trick. I lake tested the boat and it was fine.

I'm still having throttle issues. I don't think I have a servo on my '08 LSV either. What does it mean to "flash" your ECM & what's an ECM?

The way it was explained to me is that its like rebooting a computer. They hooked up a laptop to the boat's "brain" and rebooted it.

Hi,

SO did flashing the ECM work for everyone?

I have the same problem with '08 LSV. 1 mechanic says its complete electrical failure and over heating, the other says its the throttle sensors... of which both guys have looked at the boat and haven't fixed it to date.

So if we ask to get the ECM flashed, hopefully this will sove the issue??..

It worked for me. I've used the boat twice and the problem has not returned. I am keeping my fingers crossed (toes too).

Here is a link to perfect pass troubleshooting guide. It looks like the No throttle response at WOT is due to an open VGOV (See below)

Problem #2 VGOV Line Open (RQST Line OK) – With the PerfectPass system
control ON, the engine will not go above idle no matter how far the manual
throttle is pushed. With PerfectPass control OFF, the engine is controlled as
normal by manual throttle handle.
