SE So Dak
Has anybody else gotten this code and fixed the problem? It says it's a Fuel Temp Sensor low voltage. Kills the engine when it throws the code and only seems to throw it under heavy throttle. It will start right back up and runs fine at a slow to moderate speed. Any suggestions would be appreciated!

Not that it’s related but I had an oil pump code that was caused by damaged wiring. The throttle cable had rubbed on the loom so long it wore through the wire insulation and also through the plastic covering over the throttle cable. Then the steel part of the cable caused issues rubbing on the bare wires.
