Code P010D Infiniti Description

The P010D code for Infiniti vehicles indicates a problem with the Mass Air Flow (MAF) Sensor on Bank 2, specifically a high input signal. The MAF sensor plays a crucial role in monitoring the amount of air entering the engine, which is essential for the proper air-fuel mixture required for combustion. When the MAF sensor on Bank 2 sends a high input signal, it means that the airflow reading is higher than expected, potentially leading to an incorrect fuel mixture being delivered to the engine. This can result in poor engine performance, reduced fuel efficiency, and increased emissions.

Tech Notes for P010D Infiniti

Before replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with low compressed air or Mass Air Flow Sensor Cleaner. Reset code and drive vehicle. If the code comes back, it may be necessary to replace the mass air flow sensor.

When is the Code Detected?

An excessively low voltage from the sensor is sent to Engine Control Module (ECM).
