Code P0323 Description
The diagnostic trouble code P0323 indicates an issue with the Ignition/Distributor Engine Speed Input Circuit being intermittent. This code is commonly found in vehicles with a distributor-based ignition system. The Engine Control Module (ECM) uses signals from the crankshaft position sensor to determine the engine speed and ignition timing. When the ECM detects an intermittent signal from the ignition/distributor engine speed input circuit, it triggers the P0323 code.
Common Causes of P0323
- Loose or corroded wiring connections
- Faulty crankshaft position sensor
- Malfunctioning ignition module
- ECM software issues
- Physical damage to the distributor
Symptoms of P0323
- Engine misfires
- Rough idling
- Poor acceleration
- Engine stalling
- Check Engine Light illuminated
How to Fix P0323
- Begin by conducting a thorough visual inspection of the wiring connections related to the ignition/distributor engine speed input circuit. Repair or replace any damaged or corroded wires.
- Test the crankshaft position sensor using a multimeter to ensure it is functioning correctly. Replace the sensor if necessary.
- Check the ignition module for any signs of damage or malfunction. Replace the module if it is faulty.
- If the issue persists, perform a diagnostic scan of the ECM to identify any software issues. Update or reprogram the ECM as needed.
- Finally, clear the diagnostic trouble codes from the ECM and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P0323
