Details of the Dodge p2202 OBD Code

Dodge fault code P2202 relates to the NOx sensor circuit low input for bank 1.

Dodge OBD code P2202 means that the NOx sensor circuit low input bank 1 has a low voltage condition.

This code is triggered by the Engine Control Module (ECM) when it detects a low voltage signal from the NOx sensor located in bank 1 of the exhaust system.

The NOx sensor is responsible for monitoring the level of nitrogen oxide emissions in the exhaust gases.

When the voltage signal from the sensor is lower than expected, the ECM sets code P2202 to indicate a potential issue with the NOx sensor or its circuit.

Mechanic’s Tech Notes

For Dodge code P2202, check for issues with the NOx sensor circuit.

To diagnose and fix OBDII code P2202 in a Dodge, start by checking the TCM power and ground using a multimeter.
