Details of the Dodge p2190 OBD Code

Dodge fault code P2190 indicates a rich airfuel mixture in bank 2.

Dodge OBD code P2190 means that the oxygen sensor signal stuck lean on bank 2. This code is triggered by the Engine Control Module (ECM) when it detects a lean air/fuel mixture condition on bank 2 of the engine.

The oxygen sensor is responsible for monitoring the oxygen content in the exhaust gases and providing feedback to the ECM for proper fuel mixture control.

In this case, the signal from the oxygen sensor on bank 2 is indicating a consistently lean air/fuel mixture, which can be caused by issues such as a vacuum leak, fuel delivery problems, or a faulty oxygen sensor.

Mechanic’s Tech Notes

For Dodge code P2190, check for a possible vacuum leak in the intake system.

To diagnose and fix OBDII code P2190 on a Dodge, start by checking the oxygen sensor (Bank 2 Sensor 1) for proper operation.

Use a voltmeter to test the sensor’s voltage output and ensure it fluctuates correctly.

Next, inspect the wiring harness and connectors related to the oxygen sensor for any damage, corrosion, or poor connections.

Clear the code and see if it returns after driving.

If the issue persists, consider replacing the oxygen sensor.

Additionally, using a scan tool to monitor live data can help pinpoint any abnormalities in the sensor’s readings.
