Troubleshooting Hints
- If an unexpected shock or engine stall occurs in running, try to shake the harness of crankshaft position sensor.
Check the sensor connector(s) for defective contacts if engine stalls in the case.
- If 0 RPM is indicated on tachometer with the engine in idling, check for faulty crankshaft angle sensor, damaged timing belt or faulty ignition system.
- Check for the points as below if the crankshaft angle sensor indicates a value out of the specification though the engine is available of starting in idle.
- Faulty engine coolant temperature sensor.
- Faulty idle speed control motor.
- Failed standard idle speed control.
