How To Repair Manifold Pressure Sensor
The manifold pressure sensor, also known as the manifold absolute pressure (MAP) sensor, senses the air pressure in the engine's intake manifold. These sensors came into use mainly on OBDII engines and are used to calculate the difference between the manifold pressure and the ambient air pressure. With respect to the reading from the MAP sensor, the Engine Control Unit (ECU) regulates the fuel sent to the engine and its ignition timing, for obtaining optimal efficiency.
A defective MAP sensor will let the engine run lean/rich, thereby causing increased emissions. It will also induce engine problems such as idling and surging. As the engine malfunctions, the vehicle will run with poor mileage and efficiency. The MAP sensor may also report incorrect readings due to a bad fuel pump or EGR valve. A bad EGR valve allows less air to flow through the manifold while a damaged fuel pump sends less fuel to the manifold.
