NTK (NGK) MAF Sensor EPBMFN5-D004P (93343)

MAF sensors have become an integral part of the engine management system. Their task is to send information to the vehicle’s engine control unit (ECU), enabling it to control the air-fuel mixture needed by the engine to operate efficiently. NTK MAF sensors undergo rigorous tests to ensure they meet or even exceed the highest standards.

The majority of MAF sensors come in two variations: hot-wire technology and hot-film technology. These MAF sensors have no moving parts and use electrical current to measure air mass.

Situated between the intake manifold and the air filter, the MAF sensor is a vital part of the engine management system and determines the amount of air flowing into the intake system of diesel and petrol combustion engines. Based on the air mass information, the engine control unit is able to balance and deliver the correct fuel quantity to the engine. In diesel engines, the MAF sensor serves mainly to control the exhaust gas recirculation (EGR).
