Tridon MAP Sensor - TMP144

The manifold absolute pressure sensor, sometimes known as a MAP sensor, is an electrical device designed to measure manifold pressure within the vehicle intake manifold.The MAP sensor is normally located in the vehicle inlet manifold or throttle body assembly. The sensor converts the inlet vacuum (manifold pressure) into an electrical output voltage or frequency as required by the ECU.Common symptoms of a faulty, worn or inoperable MAP sensor may include illumination of the engine check light, poor fuel consumption, fuel delivery problems, engine knock, poor engine performance, hesitation or stumble during acceleration or difficult starting, engine cut out, increased fuel consumption and increased exhaust emissions.The manifold absolute pressure sensor must be compatible with the vehicle engine management system, always refer to the vehicle application list to ensure correct part number selection.
