Why does my Car Throttle quit responding while driving?

Driving – cold: throttle respons is bad, then a few seconds later its OK,…. then no matter what speed I’m driving the throttle is all of a sudden not responding any more. It feels like my throttle is freezing up,….NOT litterally ofcourse,…..the foot-pedal pumping action works throughout this “freezeup” session.

What causes a dead pedal on a Cummins?

This is the procedure for the individual sensor as opposed to the whole assembly. This sensor is one of the potential causes of “dead pedal.” Troubleshoot by back probing sensor harness and watching sensor range voltage (with key on engine off), on a multimeter, for a smooth sweep from .6VDC at idle position to 3.8VDC at full throttle position.

Why is my throttle position sensor not working?

The reason this happens is that the ECM doesn’t get correct information from the TPS as to how much to throttle the car. Idle surging can be caused due to other issues in the car, but if it happens in conjunction with other throttle position sensor symptoms, the culprit is often the TPS.
