Why do I have fault code p0108 OBD II?

Why do I have fault code p0108 OBD II?

The reasons why the fault code P0108 OBD II can be established are: There may be leaks in the vacuum supply line to the Multiple Absolute Pressure Sensor (MAP). Maybe there is a vacuum leak from the engine. The signal cable from the Manifold Absolute Pressure (MAP) sensor to the Powertrain Control Module (PCM) may be short-circuited.

What causes a p0108 code on a Mil?

MIL (Malfunction Indicator Lamp) will likely be on Potential causes of a P0108 code: A good way to diagnose if the MAP sensor is to blame would be to compare the KOEO (key on engine off) MAP sensor reading on a scan tool with the Barometric pressure reading. They should be the same because they both measure atmospheric pressure.

What causes low vacuum in a p0108 manifold?

Potential causes of a P0108 code: Bad MAP sensor. Leak in vacuum supply line to MAP sensor. Engine vacuum leak. Short on signal wire to PCM. Short on reference voltage wire from PCM. Open in ground circuit to MAP. Worn engine causing low vacuum.

What does the OBD II fault code p0108 mean?

What Does Code P0108 Mean? OBD II fault code P0108 is defined as “ Manifold Air Pressure/Barometric Pressure Circuit High Input”, and is set when the PCM (Powertrain Control Module) detects a signal from the MAP (Manifold Air Pressure Sensor) that falls outside of the expected value for the reigning engine load or throttle position,

What should vacuum reading be on p0108 manifold?

But, if the actual engine vacuum reading is 16 in. Hg or more, then unplug the MAP sensor. The scan tool MAP reading should indicate that there is no voltage present. Check that the ground from the PCM is intact and also that the MAP sensor connector and terminals are tight.

What are the common causes of code p0107?

As with symptoms, the common causes of code P0107 and its closely related codes, P0108 and P0109 much the same on all applications. Note however, that one common cause, a poorly running engine, could set other codes along with P0107, P0108,and P0109, depending on the particular application. Below are some common causes this group of codes-
