Air flow meter (AFM / MAF sensor) for the 5.0L V8 petrol engine (AJ133), fitted in the intake air system between the air filter and the throttle body. It measures the mass of air b eing drawn into the engine and reports it to the engine control module, which uses that signal to set fuelling and ignition timing. A contaminated or drifting sensor commonly presents as poor throttle response, uneven running or a lean/rich mixture fault code. Show more
