Manifold Absolute Pressure Sensor (MAP Sensor)

The manifold absolute pressure sensor (MAP sensor) is one of the sensors used in an internal combustion engine's electronic control system. The manifold absolute pressure sensor can send the information of air mass flowing into the engine to the ECU. Then the information can be used to calculate air density, which in turn adjusts the required fuel metering for combustion and influence the advance or retard of ignition timing. If the value of MAP sensor is high, the fuel management system will need more fuel than normal state and then reduce the fuel economy. On the contrary, if the value of MAP sensor is too low, ECU will automatically reduce the fuel-injecting amount causing unstable running of engine or power reduction.

MAP sensor need to be compatible with the car engine. With over ten years of experience in producing MAP sensor, FLY AUTO can provide you hundreds of MAP sensors with various types. We are also pleasure to recommend you the suitable MAP sensor according to your needs if you didn’t know how to choose the right one.
