2002 Chevrolet Trailblazer LT 4.2L MIL Lamp on, Won't accelerate
These 2 codes were in the system and wouldn't clear. Checked according to flow chart and it says the pedal position sensor is faulty. Replace sensor and problem still exists. When looking at pedal position sensor voltages one is at 4.96v and the other is at 5.... FIX posted 5/5/2012 19 Replies Received (View Replies)19 Replies Received (Hide Replies)
