Related Repair Advice

  • To prevent damage to the new mass airflow sensor, all dirt and debris should be cleaned out of the air filter housing and a new air filter installed
  • Mass airflow sensors (MAF) are often replaced when the problem is actually a bad connector or the sensor wiring harness.
  • High-performance style wet foam air filters are not recommended because they will damage the mass airflow sensor and cause poor performance
  • The air duct work between the mass air flow sensor and the intake manifold should be inspected for damage whenever the sensor is replaced
