Test Description

WARNING: This page is about a different car, the 2007 Saturn Vue. 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 step checks the PPS for any current or history DTCs.
  2. 5:  Test the occupant sensor serial data circuit for an open or high resistance.
  3. 6:  Test the PPS ignition 1 voltage circuit for a short to ground, a high resistance, or an open.
  4. 7:  Test the PPS ground circuit for an open or high resistance.
  5. 8:  Test the PPS ground circuit for a short to voltage.
