The MAP sensor is a near-absolute vacuum pressure sensor unaffected by fluctuations when the altitude changes. It is used to measure vacuum pressure in intake manifold and engine load. From the vacuum pressure signal we will calculate the amount of wind entering the engine. Thus the engine ECU will receive information to adjust the amount of injection and the angle of ignition.
The MAP sensor is so important, but do you know when a sensor fails? If you want to learn more, let's go along Thanh Phong Auto Refer to the article below.
Symptoms of a MAP sensor can check the Check Engine lamp and activate DTC.
A corrupted MAP sensor may be caused by a circuit fault, contamination, or clogging. Sometimes, a vacuum crack or engine heat that exceeds the tolerance of electronic devices can also cause the MAP sensor to fail.
When the MAP sensor is broken, ECU will miscalculate the engine load resulting in excess or fuel shortage.
Increased fuel costs: If the ECM does not have a vacuum, it is possible that the engine is at a high load, resulting in increased fuel and ignition time. This results in excessive energy consumption resulting in fuel consumption.
