1. Using EST, open the D_ContinuousMonitor.ssn.
2. To monitor signal voltage, run KOEO Continuous Monitor Test.
3. Monitor ICP signal voltage. Verify an active DTC for the ICP circuit.
4. If code is active, do step 6 and 7 to check circuit for the ICP sensor using the following tables.
• Circuit Checks for ICP Sensor – ECM to Valve Cover Gasket Connector
• Circuit Checks for ICP Sensor – ECM to ICP Sensor
5. If code is inactive, wiggle connectors and wires at all suspected problem locations. If circuit continuity is interrupted, the EST display DTCs related to the condition.
6. Disconnect engine harness from valve cover gasket connector.
NOTE: Inspect connectors for damaged pins, corrosion, or loose pins. Repair if necessary.
7. Connect VC Gasket Breakout Harness to engine harness only.
