2011 GMC Sierra 1500 P2135 Code: Idle Issues After Throttle and Accelerator Sensor Replacement

Model: 2011 GMC Sierra 1500 Fault Code: P2135 Posted: 2017-11-24 17:17

I recently replaced both the accelerator pedal sensor and the throttle body sensor in my 2011 GMC Sierra 1500. The P2135 diagnostic code has not returned, but I'm still experiencing a high idle speed after accelerating. Is this normal? I've heard that recalibration is required after replacing these sensors—does this apply to my vehicle model and year?
