DTC P0108 (3) Advanced Diagnostics

DTC P0108:

Manifold Absolute Pressure (MAP) Sensor Circuit High Voltage










General Description

The manifold absolute pressure (MAP) sensor senses manifold absolute pressure (vacuum) and converts it into electrical signals. The MAP sensor outputs low signal voltage at high vacuum (throttle valve closed) and high signal voltage at low vacuum (throttle valve wide open). If the signal voltage from the MAP sensor is a set value, the powertrain control module (PCM) detects a malfunction and stores a DTC.

Malfunction Threshold

The MAP sensor output voltage is 4.49 V or more for at least 2 seconds.

Diagnosis Details

Conditions for setting the DTC

When a malfunction is detected, the MIL comes on and a Pending DTC, a Confirmed DTC, and the freeze data are stored in the PCM memory.

Conditions for clearing the DTC

The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the Pending DTC, the Confirmed DTC, and the freeze data can be cleared with using the scan tool Clear command or by disconnecting the battery.
