Hello everyone. I'm quite new to this forum (5 minutes!) and I'm hoping you can help me out.
We have a newish (2007) generator with a Cat C15 engine in it. The controller module is telling me that there is an invalid signal coming from the TPS sensor.
Does this mean I need to replace the sensor, or is there some repair or maintenance that can be done on it?
If it needs replacement, can anyone recommend a source for this part?
Thanks much!!

Is unit running? Does it run? What was the actual code? Is it an emcp3 controller? emcp2?

WOW all you hijackers!! start a new thread idiots! As for thetvguy's problem, is the throttle responding? If its still working then your sensor prob isnt the problem, more of a poor connection or wiring problem. If its not responding then check for continuity at the ecm plug wiring to your tps plug. Make sure you have voltage on one of the wires to your tps also. If it all checks out, change the sensor.
