Throttle Body Potentiometer is the throttle position sensor on the V8 EFi petrol engine. Mounted on the throttle body and driven by the throttle spindle, it signals throttle plate angle to the engine management ECU, which uses that reading to set fuelling and idle to driver demand. A worn or erratic potentiometer causes hesitation, surging and unstable idle. Show more
