Possible Causes of B1142 Code in Nissan
The B1142 code in Nissan indicates a problem with the diagnosis sensor unit. This code is usually triggered when the sensor unit fails to communicate with the engine control module (ECM) or when there is a malfunction in the sensor unit itself. Here are some of the possible causes of the B1142 code:
- Failed Diagnosis Sensor Unit: The most common cause of the B1142 code is a failed diagnosis sensor unit. This sensor is responsible for monitoring the airbag system and communicating with the ECM. If the sensor fails, it can trigger the B1142 code.
