The P122E fault code refers to the Nitrogen Oxide Sensor Binary Oxygen Sensor on the left side of the vehicle.

The Engine Control Module (ECM) is responsible for monitoring this sensor. When the sensor does not meet the factory specifications, the ECM sets the P122E code in the On-Board Diagnostic II (OBDII) system. This code indicates a problem with the Nitrogen Oxide Sensor Binary Oxygen Sensor on the left side of the vehicle.

What are the possible causes of the P122e fault code and how can I visually inspect them?

If you’re experiencing the P122e fault code with your engine light 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 visually inspect these possible causes, check the wiring harness and connectors for any damage. Look out for broken, bent, pushed out, or corroded pins on the connectors. By conducting this inspection, you can identify any issues and take the necessary steps to fix them.

How can I determine if the Nitrogen Oxide Sensor Binary Oxygen Sensor harness is open or shorted?

If your engine light is on or you have a service engine soon warning light, it could be due to a faulty Nitrogen Oxide Sensor Binary Oxygen Sensor or an open or shorted harness. To determine if the harness is open or shorted, visually inspect the wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins. This will help you identify and fix the issue.

What steps should I take to check for damaged components and inspect the wiring harness and connectors for the P122e fault code?

To check for damaged components and inspect the wiring harness and connectors for the P122e fault code, start by visually inspecting the related wiring harness and connectors. Look for any signs of damage, such as broken, bent, pushed out, or corroded connector pins. Additionally, check the “Possible Causes” listed above, which include a faulty Nitrogen Oxide Sensor Binary Oxygen Sensor and an open or shorted harness or circuit. By following these steps, you can identify and address any issues causing the engine light to be on.
