How Do I Clean MAP/MAF Sensors?

MAP sensors can typically be cleaned using an electrical parts cleaner and a clean, lint-free rag. Be sure to follow the manufacturer's recommendations and allow the sensor to dry completely before reinstalling.

Mass Air Flow (MAF) sensors should only be cleaned with an MAF-specific cleaner, which is available at most auto parts stores. Avoid using brake cleaner, carburetor cleaner, or other solvents, as they may damage the sensor.

When cleaning an MAF sensor, avoid touching the internal sensing elements. Simply spray the MAF cleaner onto the sensor, allow it to dry completely, and reinstall it.

Keep in mind that if a sensor is damaged or continues to cause drivability issues after cleaning, replacement may be necessary.
