Bosch Mass Air Flow Sensor | 0280218088
Make Sure It Fits
- The mass air flow sensor on your Volvo measures the density of the air entering the engine so the engine control unit can determine how much fuel the engine needs based on driver demand. It functions by using a heated wire inside the sensor that is cooled by the air flowing over it. The cooler the air is, the denser it is and the more it can cool the hot wire in the sensor. This is important too for the engine computer to be able to accurately determine exactly how much fuel should enter the cylinders to be completely burned, maximizing performance, and reducing emissions. Failure of the mass air flow sensor can happen in a couple of ways. One way is a simple electrical failure of the sensor. When this happens, no reading is sent to the engine computer and the engine will run off predetermined parameters, a fault will be stored, and your check engine light will come one. Another way for the mass air sensor to fail is contaminants from the air entering the engine collect on the hot wire in the sensor. When this happens, the hot wire becomes insulated and the sensor will think the air entering the engine is warmer than it is and not as dense, causing the engine computer to think less fuel is needed, and the engine to lose power and run lean increasing emissions.
