Test Description

WARNING: This page is about a different car, the 2004 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.

The numbers below refer to the step numbers on the diagnostic table.

  1. 2:  This tests the position sensor signal voltage range using a scan tool. The scan tool will display 0 volts for all position sensors if any position sensor 8 volt reference circuit is shorted to ground.
  2. 3:  This tests if any position sensor is shorted to ground.
  3. 4:  This tests determines which position sensor is shorted to ground.
  4. 5:  Tests for a short to ground in the position sensor 8 volt reference circuits.
  5. 6:  Tests for a short to voltage in the position sensor 8 volt reference circuits.
