The fault code P0102 refers to a transmission code in general. This code is for OBD-II equipped cars with a Mass air Flow sensor. Toyota, Infiniti Nissan, Jaguar Audi Mercedes, Dodge, Hyundai Chevy Ford etc. are just a few of the brands. The specific steps of repair may differ depending on the model and make. The MAF sensor is used to determine the volume, density, and temperature of air that enters the engine.
The MAF generates a signal which the PCM uses to determine fuel management. When the PCM determines this signal has been below specification for an extended period, it sets the P0102 codes.
Some MAF sensors include an air-temperature sensor that is used by the PCM to optimize engine performance.
P0100, P0101, P0103 and P0104 are other fault codes that may be related to the MAF.

What are the causes of fault code P0102?
- Electrical wiring or cabling issues with the MAF sensor (open, short-circuit, worn, weak connections, etc.).
- Intake air leaks
- Mass airflow sensor dirty
- Faulty MAF sensors
Other codes can be present along with the P0102 error code. There may be misfire codes, O2 sensor fault code or both. It is therefore important to consider the big picture when repairing your vehicle.
How to Fix Fault Code P0102?
- Inspect all air intakes for leaks. Repair them.
- Check the connectors and cables leading to the MAF sensor. They should be checked for wear, corrosion, and loose connections.
- Clean the air filter or air intakes if they are dirty.
- Try cleaning the MAF sensor before buying a new one.
- Replace the MAF sensor.
How serious is fault code P0102?
The P0102 error code is not likely to prevent you from getting to your destination. You may experience a noticeable increase in fuel consumption depending on the humidity and air quality.
