Component Tests and General Diagnostics

Testing of the Crankshaft Position Sensor (also known as a Crank Angle Sensor) without Scan Tool
Testing of the sensor involves testing of the harness. If the harness tests properly and there is an abnormality in the crankshaft position sensor system, then the sensor should be replaced. See the Diagnostic Charts for trouble code 22 - Crankshaft Position Sensor.

TROUBLESHOOTING HINTS
1. If an impact is suddenly felt during driving or the engine suddenly stalls during idling, try shaking the crankshaft position sensor during idling. If the engine stalls, the cause is probably improper or incomplete contact of the crankshaft position sensor's connector.
2. If the crankshaft position sensor output rpm is 0 rpm during cranking when the engine cannot be started, the cause is probably a malfunction of the crankshaft position sensor or a broken timing belt.
3. If the indicated value of the crankshaft position sensor output rpm is 0 rpm during cranking when the engine cannot be started, the cause is probably 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.
