i have a failed emission test for my 2007 Tahoe due to: P0121 Throttle/Pedal Position Sensor/Switch A Circuit. 1st Question: Do I replace the Accelerator Pedal Sensor or the Throttle Body to eliminate the emission test failure? 2nd Question: the parts store manager told me that if I pull the throttle pedal and clean the connections it could solve the problem -- is this accurate?
