Nissan Sunny 1.6L 2010 - Fault Codes P2138, P1229, P2127, P2122 and Unresponsive Throttle After Sensor Replacement

Model: Nissan Sunny Fault Code: P1229 Posted: 2016-05-13 09:50

I own a 2010 Nissan Sunny 1.6L and am experiencing an unresponsive throttle. The vehicle is showing fault codes P2138, P1229, P2-127, and P2122. I recently replaced the accelerator pedal position sensor, but the issue persists. The symptoms suggest a potential problem with the throttle body or related electronic control modules. I'm seeking advice on possible causes and next steps to resolve these codes and restore proper throttle response.
