NTK (NGK) MAP Sensor EPBBPN3-A012Z (91308)

MAP ensors 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 MAP sensors undergo rigorous tests to ensure they meet or even exceed the highest standards.

MAP sensors can be classified in two groups: manifold pressure type and boost pressure type. They provide immediate data on the manifold/boost pressure to the ECU, measuring air pressure to make calculations for fuel, and ignition calibration, which is vital to maintain engine efficiency.

The MAP sensor measures the air pressure by the deformation of a membrane with integrated resistors. The pressure varies depending on the throttle position, engine speed, and turbo operation. The Boost Pressure Sensor, in turn, is used in turbocharged engines and located between the turbocharger and intake manifold.
