Disconnect the APS and PCM/ECM connectors and inspect for looseness, poor connection, bending, corrosion, contamination, deterioration or damage. Reconnect the connectors.
Connect the GDS and go to “Current Data”.
Monitor APS values in Current Data, check and wiggle the harness(es), connector(s), and terminal(s).
Any change in the values indicates a poor connection. Was a connector problem found?
