If the code returns, further diagnosis may be needed to check for any underlying issues.

Cost Of Fixing Dodge p0108 Fault Code

Diagnosing and repairing Dodge code P0108 involves testing and potentially replacing the manifold absolute pressure sensor.

The cost to diagnose and fix a Dodge OBD code P0108 typically ranges from $75 to $150, based on a 1. 0hour repair time.

Factors like shop rates and complexity can affect the final cost.

Details of the Dodge p0108 OBD Code

Dodge fault code P0108 relates to a high voltage input from the manifold absolute pressure sensor.

Dodge OBD code P0108 means there is a problem with the Manifold Absolute Pressure (MAP) sensor circuit.

This code is triggered when the Engine Control Module (ECM) detects that the voltage from the MAP sensor is too high.

The MAP sensor measures the intake manifold pressure, which is used by the ECM to calculate engine load and adjust fuel delivery.

When P0108 is set, it indicates a potential issue with the MAP sensor itself, the wiring/connectors to the sensor, or the intake manifold.

Mechanic’s Tech Notes

Detailed information on diagnosing and repairing Dodge code P0108 related to the manifold absolute pressure sensor circuit.

To diagnose and fix OBDII code P0108 on a Dodge, start by checking the MAP sensor circuit.

Use a voltmeter to test the sensor’s voltage supply and ground.

Ensure the sensor is receiving proper voltage.

Check the wiring harness and connectors for any damage, corrosion, or loose connections.

Inspect the sensor for any signs of physical damage.

If everything looks good, consider replacing the MAP sensor itself.

Clear the code and retest to verify the issue is resolved.

If the problem persists, further diagnosis with a scan tool may be necessary to pinpoint the exact cause.
