The P0322 code indicates the engine control module is not receiving a signal from the ignition distributor or engine speed input circuit. This prevents the computer from determining engine position and timing, often resulting in a no-start condition. It is most common on vehicles utilizing distributor-based ignition systems or specific early electronic ignition setups.
Harness chafing, corrosion, or disconnected plugs interrupt the signal path.
The internal winding or magnetic element within the distributor or sensor fails.
The module processing the signal may have internal circuitry damage.
Physical misalignment prevents the sensor from reading the reluctor ring.
A protective fuse may have opened due to a short or overload.
Internal processor failure is rare and should only be considered after all other inputs are verified.
No, the condition usually persists until the signal loss is repaired.
No, the vehicle will likely not start or will stall unexpectedly.
No, PCM failure is rare; wiring and sensors are the usual causes.
It is similar, but P0322 specifically references the distributor or ignition speed input on applicable vehicles.
