Details of the Dodge p0320 OBD Code

Dodge fault code P0320 indicates an issue with the ignition/distributor engine speed input circuit.

Dodge OBD code P0320 means that there is an issue with the ignition/distributor engine speed input circuit.

This code is triggered when the Engine Control Module (ECM) does not receive a proper engine speed signal from the crankshaft position sensor.

The crankshaft position sensor is the component that triggers this fault code.

It is responsible for monitoring the rotational speed and position of the crankshaft, providing vital information to the ECM for ignition timing and fuel injection.

When the ECM detects a lack of signal from the crankshaft position sensor, it sets code P0320, indicating a problem with the engine speed input circuit.

This can lead to issues with engine performance, misfiring, and even stalling.

Mechanic’s Tech Notes

Detailed information on diagnosing and repairing Dodge fault code P0320 related to the ignition/distributor engine speed input circuit.

To diagnose and fix OBDII code P0320 on a Dodge, start by checking the crankshaft position sensor (CKP) circuit.

Use a voltmeter to test the CKP sensor’s resistance and voltage output.

Inspect the sensor for any physical damage or contamination.

Next, check the wiring harness and connectors for any issues like breaks, corrosion, or poor connections.

Ensure the CKP sensor is properly aligned and installed.

If all checks out, consider testing the power and ground circuits of the Transmission Control Module (TCM) using a multimeter.

Verify TCM communication over the Controller Area Network (CAN) using a scan tool.

Reflashing the TCM software may be necessary if no faults are found in the wiring or sensor.
