The MAP sensor detects the air pressure at the inlet of the vehicle and turns it into an electrical signal which is sent to the engine’s electronic control unit (ECU) to regulate the stoichiometric mixture.

Some of FAE’s models have a NTC type temperature sensor allowing the MAP sensor to detect pressure and the air temperature at the inlet.

Mass of intake air is calculated by the ECU which on its turn adjusts the optimum air-fuel mixture.

All FAE sensors are manufactured in an ESD room and are submitted during the assembly to leakage tests and output voltage verifications.
