What does P0102 mean?

This code means the Mass Air Flow (MAF) sensor is reporting a low signal. This can lead to incorrect fuel mixture calculations by the engine computer.

• Dirty or faulty Mass Air Flow (MAF) sensor
• Air leaks in the intake system after the MAF sensor
• Wiring problems to the MAF sensor

Click steps to track your progress.

1. 1

   Clean the Mass Air Flow (MAF) sensor using a specialized MAF sensor cleaner.

2. 2

   Check the air intake system for any leaks or loose connections after the MAF sensor.

3. 3

   Inspect the wiring harness and connector for the MAF sensor for damage or corrosion.
