Component Testing

WARNING: This page is about a different variant/trim than selected.
NOTE: You must perform the Circuit/System Testing before proceeding with Component Testing.
  1. Inspect the B26 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 B26 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 with a scan tool. Pass a flat steel object by the tip of the sensor repeatedly. The crankshaft position active counter parameter should increment.
    • If the function does not perform as specified, replace the B26 crankshaft position sensor.
