Trouble Shooting Hints
- If an impact is suddenly felt during driving or the engine suddenly stalls during idling, try shaking the crank angle sensor during idling. If the engine stalls, the cause may be presumed to be improper or incomplete contact of the crank angle sensor's connector.
- If the crank angle sensor output RPM is zero RPM during cranking when the engine cannot be started, the cause may be presumed to be a malfunction of the crank angle sensor or a broken timing belt.
- If the indicated value of the crank angle sensor output RPM is zero RPM during cranking when the engine cannot be started, the cause may be presumed to be a failure of the ignition coil's primary current to intermittently pulse correctly, so a malfunction of the ignition system circuitry, the ignition coil and/or the power transistor is the probable cause.
- If idling is possible even though the crank angle sensor indicated RPM is a deviation from the standard value, the cause is usually a malfunction of something other than the crank angle sensor. For example:
- Malfunction of the coolant temperature sensor.
- Malfunction of the idle speed control servo.
- Improper adjustment of the standard idling speed.
