Details of the Dodge p0152 OBD Code

Dodge fault code P0152 relates to the oxygen sensor circuit high voltage condition.

Dodge OBD code P0152 means that the O2 sensor circuit high voltage for bank 2 sensor 1 has been detected.

This code is triggered by the Engine Control Module (ECM) when the voltage signal from the upstream oxygen sensor in bank 2 reads higher than normal for an extended period of time.

The O2 sensor is part of the emissions control system and is involved in monitoring and adjusting the airfuel mixture for optimal combustion efficiency.

Mechanic’s Tech Notes

For Dodge code P0152, the oxygen sensor circuit high voltage is detected in bank 2 sensor 1.

To diagnose and fix OBDII code P0152 on a Dodge, start by using a voltmeter to test the oxygen sensor (Bank 2 Sensor 1) for proper voltage output.

Check the sensor’s wiring harness and connector for any damage, corrosion, or loose connections.

If everything looks good, the issue may lie with the sensor itself, requiring replacement.

Additionally, using a scan tool to monitor live data can help confirm the sensor’s performance and identify any other potential issues in the system.

If the sensor readings are out of range, replacing the oxygen sensor should resolve the P0152 fault code.
