DESCRIPTION
The mass air flow sensor (or MAF) detects the volume of air coming into the engine so that the computer can accurately calculate the air/fuel ratio for the optimum performance and efficiency. As a sensitive intrument, the MAF sensor can become dirty and deteriorate over time, affecting its readings. Malfunctions can cause reduced performance, poor fuel economy, and the ominous ‘check engine’ light.
