-
Check the electrical harness connector for damage, corrosion, loose or broken terminals.
-
If necessary, repair the faulty wiring connection.
If the specification was obtained:
Checking Ground (GND) activation
If the specified value was not obtained:
If the manufacturers test box is being used. Perform the following step.
-
Install the test box.
If the manufacturers test box is not being used. Perform the following step.
-
Remove the Engine Control Module (ECM) J623.
-
Using a multimeter, check the Oxygen Sensor (O2S) Behind Three Way Catalytic Converter (TWC) G130 electrical harness connector to the
Engine Control Module (ECM) J623 electrical harness connector T121 for resistance.

Specified value: 1.5 ohms max.
If the specification was not obtained:
-
Check the wiring for an open circuit, a short circuit to each other, Battery (+), or Ground (GND).
-
Check the electrical harness connector for damage, corrosion, loose or broken terminals.
-
If necessary, repair the faulty wiring connection.
If no malfunction is found in the wiring and if the voltage supply was OK:
-
Erase the DTC memory. See: Testing and Inspection/Scan Tool Testing and Procedures/Diagnostic Mode 04 - Erase DTC Memory
-
Perform a road test to verify repair.
If the DTC does not return:
Repair complete, Generate readiness code. See: Testing and Inspection/Monitors, Trips, Drive Cycles and Readiness Codes
-
End diagnosis.
If the DTC returns and no malfunction is found in the wiring and the voltage supply was OK:
-
Replace the Engine Control Module (ECM) J623.
-
Assembly is performed in the reverse of the removal.
Final procedures
After repair work, the following work steps must be performed in the following sequence:
1. Check the DTC memory. See: Testing and Inspection/Scan Tool Testing and Procedures/Diagnostic Mode 03 - Read DTC Memory
2. If necessary, erase the DTC memory. See: Testing and Inspection/Scan Tool Testing and Procedures/Diagnostic Mode 04 - Erase DTC Memory
3. If the DTC memory was erased, generate readiness code. See: Testing and Inspection/Monitors, Trips, Drive Cycles and Readiness Codes
