2002 GMC Yukon XL Denali Question: throttle position sensor

 

Question

The GMC mechanic at the local shop says the Throttle Position Sensor cannot be replaced on my 2002 GMC Yukon XL Denali. He says a new throttle body is required. Is an entire new throttle body the only way to fix this?

    i guess it depends on whats wrong, i dont think you have a TPS - it uses a pedal position sensor. if u have TPS like problem i guess it would be the PPS

    I can order a TPS online for the Yukon, specially for the XL Denali, according to the parts store. It also has a PPS. It has intermitten stalling during acceleration. Only does it maybe once a week.

    One year later, the Denali stranded us on the interstate in Indiana. It was a bad fuel pump, overheating and shutting down the engine, until it finally just quit. $950 to fix.
