Mini cooper mass air flow sensor problems
If you notice that your car is much slower than usual, there is a significant risk that your MAF sensor is at fault. A faulty MAF sensor can cause a faulty air-fuel mixture and it can cause many strange performance issues with your car and slow acceleration is one of them. Your engine needs a perfect air-fuel mixture in the combustion chamber for optimal performance. But, if your check engine light is illuminating you want to check the diagnostic trouble codes first with an OBD2 scanner. However, the engine control module does not always recognize a faulty MAF sensor, so it may still be defective even if there is no engine light on your dashboard. Therefore, if your MAF sensor is faulty and sends wrong information to the engine control unit – the check engine light will illuminate your dashboard. If a sensor sends an incorrect signal, the ECM or PCM will turn on the check engine indicator light. The engine control module monitors all sensors in the car engine to ensure that everything is OK.
