Crankshaft Position Sensor

Inspect/Test/Service/Replace

  • The sensor is mounted in a fixed position in the engine block. The tip of the sensor protrudes into the crankcase at a distance of 0.05 plus or minus 0.02 inch from the crankshaft.
  • A crankshaft adjusting tool may be used to check these rings.
    • Place the tool on the pulley extension surface and rotate the tool around the pulley.
    • If any blade touches the tool, replace the pulley.
  • Inspect the trigger wheel behind the crankshaft pulley and the sensor for damage.
  • If the engine misfires all the time or on acceleration only, test the following components:
    • Engine compression.
    • Spark plugs.
    • Spark plug wires.
    • Ignition coils test for firing voltage with a test spark plug.
    • Crankshaft sensor.
    • Fuel injectors on multiport and sequential fuel injection systems.
