The P122F fault code refers to a problem with the Nitrogen Oxide Sensor Binary Oxygen Sensor in your vehicle. The Engine Control Module (ECM) is responsible for monitoring this sensor, and it sets the OBDII code when the sensor is not functioning according to factory specifications. In this case, the fault code indicates a short circuit in the Nitrogen Oxide Sensor Binary Oxygen Sensor.

When this fault code appears, it means that there is an issue with the sensor’s electrical circuit.

A short circuit can occur when there is a direct connection between the positive and negative terminals of the sensor, causing an abnormal flow of electrical current.

This can lead to inaccurate readings and affect the overall performance of the vehicle.

To fix this problem, it is important to inspect the wiring and connections related to the Nitrogen Oxide Sensor Binary Oxygen Sensor.

Look for any damaged or loose wires, and ensure that all connections are secure.

If any issues are found, they should be repaired or replaced as necessary.

It is also recommended to clear the fault code from the ECM after the repairs have been made to ensure that the issue has been resolved.

What are the possible causes of the P122F fault code and how can I check them?

If you’re seeing the P122F fault code and your engine light is on, it could be due to a faulty Nitrogen Oxide Sensor Binary Oxygen Sensor or issues with the sensor’s harness and circuit connection. To check for these possible causes, visually inspect the wiring harness and connectors, looking for any damage or corrosion. Additionally, check for broken, bent, or pushed out connector pins. Taking these steps can help you identify and fix the problem.
