Specs At A Glance

Good To Know

Q: Will this sensor fix a check engine light on my Q45? A: A MAF-related code is often cleared by replacing a failed sensor, but confirm the fault code points to the sensor before ordering. Other faults can set similar codes.

Q: Can I install this mass air flow sensor myself? A: Yes, it mounts in the intake tract and connects to the factory harness plug with basic hand tools. Disconnect the battery and handle the sensing element carefully during installation.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
