Component Testing

IMPORTANT: You must perform the Circuit/System Testing before proceeding with Component Testing.
  1. Inspect the crankshaft position sensor for looseness and correct installation. Remove the crankshaft position sensor from the engine and inspect the sensor and the O-ring for damage.
    • If the sensor is loose, incorrectly installed, or damaged, repair or replace the crankshaft position sensor.
  2. Connect the crankshaft position sensor connector to the crankshaft position sensor; turn ON the ignition, with the engine OFF.
  3. Observe the Crankshaft Position Active Counter parameter on the scan tool; pass a steel object by the tip of the sensor repeatedly. The Crankshaft Position Active Counter parameter should increment.
    • If the parameter does not increment, replace the crankshaft position sensor.
