Details of the Jeep p0320 OBD Code
Fault code P0320 in a Jeep indicates an issue with the ignition/distributor engine speed input circuit malfunction.
OBD code P0320 for a Jeep means that there is an issue with the ignition/distributor engine speed input circuit.
This code is triggered by the Engine Control Module (ECM) when it does not receive a proper engine speed signal from the ignition system.
In simpler terms, this code indicates a problem with the crankshaft position sensor or the wiring associated with it.
The crankshaft position sensor is responsible for providing the ECM with information about the engine’s speed and position, which is crucial for proper ignition timing and fuel delivery.
When P0320 is set, it typically points to a faulty crankshaft position sensor, damaged wiring/connectors related to the sensor, or issues with the sensor’s reluctor ring.
It’s important to inspect these components carefully to determine the exact cause of the problem and proceed with the necessary repairs.
Mechanic’s Tech Notes
For Jeep code P0320, check the crankshaft position sensor circuit for faults or failures.
For Jeep OBDII code P0320 (Ignition/Distributor Engine Speed Input Circuit Malfunction), start by checking the crankshaft position sensor (CKP) and its wiring harness for any damage or loose connections.
Use a voltmeter to test the CKP sensor’s resistance and voltage output.
Ensure the sensor is properly aligned and has the correct air gap.
If the sensor checks out, inspect the power and ground connections to the Engine Control Module (ECM) for any issues.
A scan tool can help monitor the CKP sensor’s signal while the engine is running to pinpoint any irregularities.
Reflashing the ECM may be necessary if all components check out.
FAQ
Common causes of OBD code P0320 in a Jeep: Faulty CKP sensor, open/shorted CKP harness, poor CKP circuit connection, faulty PCM. Inspect wiring and connectors for damage.
Diagnose P0320 in Jeep: Check Crankshaft Position Sensor, harness, and PCM. Inspect wiring for damage or poor connection. Repair as needed.
It is not safe to continue driving with a P0320 code. The fault may cause engine issues like stalling. Inspect and repair the CKP sensor and related components.

Wrap Up
If your Jeep is experiencing stalling, rough idling, or difficulty starting, the OBD code P0320 may indicate a faulty crankshaft position sensor, damaged wiring harness, or poor sensor connection.
These issues can disrupt the engine’s timing and cause performance problems.
To address Jeep’s P0320 code, inspect the crankshaft position sensor and its wiring for any signs of damage or corrosion.
Test the sensor’s resistance and ensure proper connection to the engine control module.
Replace the sensor if necessary and repair any damaged wiring to restore proper engine operation.
