Collection: Manifold Absolute Pressure Sensors

Manifold absolute pressure (MAP) sensors are crucial components of the engine's intake system that measure the pressure inside the intake manifold. The MAP sensor detects the varying pressure levels resulting from changes in engine load & altitude. It provides important information to the engine control unit (ECU), allowing it to calculate the correct fuel injection & ignition timing for optimal engine performance. The MAP sensor uses a diaphragm or semiconductor to convert pressure changes into electrical signals that are sent to the ECU. This data helps the ECU adjust the air-fuel mixture, turbocharger boost levels, & other engine parameters to ensure efficient combustion & power delivery. A malfunctioning MAP sensor can cause drivability issues such as poor acceleration, rough idling, or even engine stalling. Regular maintenance & cleaning of the MAP sensor are important to ensure accurate readings. If a faulty MAP sensor is detected, it should be replaced to restore proper engine operation.
