Component Testing

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2012 GMC Yukon XL, 2012 GMC Yukon, 2012 Chevrolet Tahoe, 2012 Chevrolet Suburban, and 2012 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:

You must perform the Circuit/System Testing before proceeding with Component Testing.

  1. Inspect the crankshaft position sensor for correct installation. Remove the B26 crankshaft position sensor from the engine and inspect the sensor O-ring for damage.
    • If the sensor is loose, incorrectly installed, or damaged, replace the B26 crankshaft position sensor.
  2. Connect the crankshaft position sensor harness connector to the B26 crankshaft position sensor.
  3. Ignition ON, observe the Crankshaft Position Active counter parameter with a scan tool while passing a flat steel object across the tip of the sensor repeatedly. The Crankshaft Position Active counter parameter should increment with each pass of the steel object.
    • If the function does not perform as specified, replace the B26 crankshaft position sensor.
