The automobile fault code P126A indicates a problem with the Nitrogen Oxide (NOx) Sensor.
The most common symptom is the Engine Light being ON or the Service Engine Soon Warning Light.
The cause of this fault code can be a faulty NOx sensor, an open or shorted NOx sensor harness, or a poor electrical connection in the NOx sensor circuit. To fix this issue, you should visually inspect the wiring harness and connectors, checking for any damage or corrosion. Additionally, look for any broken, bent, pushed out, or corroded pins in the connectors.
The repair time for this issue is estimated to be around 1.0 hour. To interpret the fault code, refer to the “Possible Causes” listed above.

P126A Fault Code: Understanding The Description And Implications
The P126A fault code refers to a problem with the Nitrogen Oxide (NOx) Sensor in your vehicle.
The Engine Control Module (ECM) is responsible for monitoring this sensor.
When the NOx Sensor is not functioning within the factory specifications, the ECM will set the P126A code in the On-Board Diagnostic II (OBDII) system. This fault code specifically indicates a plausibility correlation issue between the Nitrogen Oxide (NOx) Sensor and the Oxygen Sensor located before the catalytic converter. The ECM detects that there is a problem with the relationship between these two sensors, which can affect the accuracy of the emissions control system. If you encounter the P126A fault code, it is important to have your vehicle inspected and repaired by a qualified technician. They will be able to diagnose the exact cause of the issue and perform the necessary repairs to ensure that your vehicle meets the required emissions standards.
Ignoring this fault code could lead to increased emissions and potential damage to the catalytic converter.
FAQ
If you’re seeing the engine light on or the service engine soon warning light, the fault code P126A might be the culprit. This code is often caused by a faulty Nitrogen Oxide (NOx) sensor, an open or shorted NOx sensor harness, or a poor electrical connection in the NOx sensor circuit.
