Quick test to tell if Mass Air Flow Sensor is bad or dirty which could be causing your car or truck to run bad or keep cutting off.
The intake air temperature sensor is set at the start procedure in conjunction with the engine coolant temperature sensor. The resistance values of both sensors supply exact information for calculating the fuel injection period. In this way hot start problems in particular are avoided. The air column in the mass air flow sensor can oscillate1. Improved Engine Performance: The Mass Air Flow (MAF) Sensor allows for a correct air/fuel ratio within the engine’s ignition chamber, resulting in improved engine performance. 2. Fuel Efficiency: The Mass Air Flow (MAF) Sensor monitors air levels and sends this data to your car’s electronic control unit. Hood Grille Replacement. Project Time: 1 hour. BMWs are known for their kidney grills. E46 models are known for their kidney grill mounting tabs failing. In this tech article we show you to replace the front grilles in your E46. Applies to: BMW 325i (2001-2005) BMW 325Xi (2001-2005) BMW 325Ci (2001-2006) BMW 325ti (2001-2004) It’s quite possible that the mass air flow sensor is either contaminated or faulty. However, it’s not the only potential problem you are facing. Here are some of the most common P0102 causes. Dirty or faulty mass air flow sensor. Intake air leaks. MAF sensor wiring problem. Dirty air filter. Faulty PCM (unusual) 25YZ.
