A map sensor stands for Manifold Absolute Pressure. Map sensor are usually located on the right side of the intake manifold behind the engine. In some models, they are located on the opposite side of the intake manifold, near the throttle body. MAP sensor help an engine control unit (ECU) to detect the air pressure in the intake pipe and determine the intake air flow.
What will you do when your engine management light comes on? Are you reading code P0106, P0107 and P0108 on your scanner? Before you rush to spend money in the garage. Let us introduce some common indicators with your map sensor.
Diagnostic trouble code (DTC) P0106:
A DTC Code P0106 indicates that it is time to clean your map sensor, it is a very common problem with map sensors. They get dirty and give wrong readings, even if the map sensor is not very dirty, we recommend that you should still clean it. Oil and dirt can easily fill the manifold, including the inside of the sensor, which has a higher possibility that causes false reading and leads to code P0106.
Diagnostic trouble code (DTC) P0107 and (DTC) P0108:
DTC P0107 stands for map sensor circuit low voltage input problem. On the other hand, DTC P0108 stands for map sensor circuit high voltage input problem.
The average voltage DC that we want to see is 1 to 1.5 volts, and usually the full throttle is about 4.5 volts. If you receive the code P0107, the circuit voltage is lower than half a volt. On the other side, with a DTC P0108, it represents that the circuit voltage is higher than four half volts, and these two values are not good. The most common cause of a DTC P0107 and DTC P0108 is a bad map sensor.
