Corrosion of the Ground Inside the Mass Air Flow Sensor on Nissan Maxima

Submitted by Vehicle Owner · May 29, 2025
Published by RepairPal

Problem overview

The ground inside mass air flow (MAF) sensor can corrode and possibly cause drivability problems. The corrosion is enough to affect the sensor data but not enough to create a trouble code. Diagnosing this can be difficult because it won't always illuminate the Check Engine Light.
