Hi, I'm new to the site, but like most people in this day and age, I go to the forums when I need help with anything. People working together to solve problems always works. I have a 2003 GMC Yukon XL with the 5.3 engine. I recently got a check engine light and a reduced power message on my dash. The guy at Autozone ran the codes and it shows the throttle position sensor or accelerator position sensor. I have found that my sensor is on the accelerator pedal arm. I want to order the part, but of course gmpartsdirect needs the part number and I don't trust the aftermarket parts. Could some one please help me find the part number. Thanks.

By the way, the eight letter in the VIN is a T. Heard that helps with getting the correct part.

Have you checked out www.rockauto.com They have a great site for locating the correct part.

if you can give me the last 8 digits of your vin i can get you a gm part number for that. I work in parts at a chevy dealer

If you have the non-adjustable pedals go to NAPA and order part # 6101088. About $60.00 and you won't have to buy the complete pedal as GM will want to sell you. There is no reason to not trust quality aftermarket parts.
