ETC Light on, P2122 P2127 – Chrysler

Fix  Chrysler ETC Light on, P2122 P2127

Chrysler has issued a service bulletin to address ETC Light on, P2122 or P2127 trouble codes on 2010 Town & Country and Grand Caravan vehicles equipped with power adjusting pedals with or without memory built before September 17, 2009 (MDH 0917XX).

ETC light on, P2122, P2127

The P2122 – Accelerator Pedal Position Sensor 1 Circuit Low and P2127 – Accelerator Pedal Position Sensor 2 Circuit Low would lead you to suspect a defective accelerator pedal position sensor. But don’t go there yet. Chrysler has determined that the wiring harness is stretched so tight that the connector may partially disconnect, causing the trouble codes and the ETC light on condition. The fix is simple; disconnect the wire harness clip (3) near the ETC sensor (2) to create more slack in the harness. Then push the connector (1) back into the APP. Clear the codes and test drive the vehicle.
