1. Using EST, open the continuous monitor session.
To monitor signal voltage, run KOEO Continuous Monitor Test.
2. To monitor signal voltage, run KOEO Continuous Monitor Test. For help, see “Continuous Monitor Test” in Section 3 (page 68).
3. Monitor APS signal voltage. Verify an active DTC for the APS/IVS circuit.
4. If code is active, do step 6 and 7 to check circuit for the APS sensor using the following table.
• Circuit Checks for APS Sensor
5. If code is inactive, wiggle connectors and wires at all suspected problem locations. If circuit continuity is interrupted, the EST will display DTCs related to the condition.
6. Disconnect chassis harness from APS sensor.
NOTE: Inspect connectors for damaged pins, corrosion, or loose pins. Repair if necessary.
7. Connect APS Sensor Breakout Harness to chassis harness only.
