Details of the Jeep p0137 OBD Code

The Jeep fault code P0137 indicates a low voltage condition in the downstream oxygen sensor.

OBD code P0137 for a Jeep indicates that the oxygen sensor in bank 1, sensor 2, has detected low voltage levels.

This sensor is located after the catalytic converter.

The Engine Control Module (ECM) triggers this code when it receives a signal indicating that the oxygen sensor voltage remains low for an extended period.

This code is related to the oxygen sensor’s function of monitoring the efficiency of the catalytic converter and the airfuel mixture.

Mechanic’s Tech Notes

Detailed information on diagnosing and repairing fault code P0137 in a Jeep vehicle.

OBDII code P0137 in a Jeep indicates a low voltage condition in the downstream oxygen sensor.

To diagnose, start by checking the downstream oxygen sensor’s wiring harness and connector for any damage or corrosion.

Use a voltmeter to test the sensor’s voltage output while the engine is running.

A healthy sensor should fluctuate between 0. 1 to 0. 9 volts.

If the voltage remains low or steady, the sensor may be faulty and require replacement.

Additionally, ensure there are no exhaust leaks affecting sensor readings.

If the sensor and wiring check out, further diagnosis with a scan tool to monitor sensor data and catalytic converter efficiency may be necessary.
