Cadillac CTS Mass Air Flow (MAF) Sensor Cleaning to Save Gas, Improve Performance and Better Idle

Step-by-step how to video to remove (or replace) and clean your mass air flow (MAF) sensor. A clean MAF can improve fuel economy, rough idle, engine hesitation, and hard cold starts. OBD scanner codes (check engine) for malfunctioning or dirty MAFs can be P0100, P0101, P0102, P0103, P0104, and P0105.

A dirty mass air flow sensor can cause your car to run sub-optimal.

A MAF helps your car run more efficiently by helping your car's computer determine the right air and gas mixture for the engine. The MAF is key part of a well functioning car.

Only use a cleaner made specifically for mass air flow sensors. There are a few manufactures. I used CRC's Mass Air Flow Sensor Cleaner, and these types of spray cleaners can be bought at many automobile parts store, hardware stores and also at online retailers.

In this video, I locate, remove and clean my 2011 Cadillac CTS MAF sensor. The video instruction applies to most other car makes and models. It's very easy to do.
