The Mass Air Flow sensor (MAF) is one of the key components of an electronic fuel injection system in your car. It is installed between the air filter and the intake manifold of the engine. See thediagram. The mass air flow sensor measures the amount of air entering the engine or theai...
Generally,throttle bodies do not need to be replaced completely, but rather just need specific parts related to them replaced. I would also recommend checking the mass air flow sensor to be sure it is functioning correctly as well since this could also cause the car to hesitate or run poorly...
Problems with the mass air flow (MAF) sensor causing the code P0171 are fairly common in many vehicles. Sometimes the mass air flow sensor just gets dirty and gives false air flow readings causing the engine to run lean. Cleaning the air flow sensor may help temporarily; the proper repair ...
