OBD-II Generic Error Code P0323: How to Fix Distributor Engine Speed Input Intermittent

Q: What does OBD-II code P0323 mean?

P0323 means the Engine Control Module (ECM) detects an intermittent or erratic signal from the distributor engine speed input circuit, often from the ignition pickup coil or crankshaft position sensor.

Q: Can I drive with a P0323 code?

Driving is not recommended as it can cause stalling, rough running, or no-start conditions. It may also affect transmission shifting and fuel economy.

Q: Is P0323 the same as P0322?

No, P0322 indicates no signal (circuit malfunction), while P0323 indicates an intermittent signal (intermittent circuit). The troubleshooting is similar.

Q: Do I need to replace the entire distributor for P0323?

Not necessarily. Often the issue is the ignition pickup coil inside the distributor, which can be replaced separately. Check the cap, rotor, and wiring first.

Costs vary by vehicle. DIY repair for a pickup coil may cost $20-$50. Professional repair including diagnostic and labor may range from $150 to $400.
