Test procedure
-
Perform a preliminary check to verify the customers complaint. Refer to => [ Preliminary Check ] See: Testing and Inspection/Scan Tool Testing
and Procedures/Preliminary Check
Start diagnosis
-
Remove the black plastic cover (right side) underneath the vehicle to access the O2S connector..
Checking internal resistance
-
Disconnect the Oxygen Sensor (O2S) Behind Three Way Catalytic Converter (TWC) (G130) electrical harness connector.
-
Using a multimeter, check the Oxygen Sensor (O2S) Behind Three Way Catalytic Converter (TWC) (G130) electrical harness connector terminals
1 to 2 for resistance.
Specified value: 2.5 to 14.0 ohms (at approx. 20° C)
If the specified value was Not obtained:
-
Replace the Oxygen Sensor (O2S) Behind Three Way Catalytic Converter (TWC) ( G130)
If the specified value was obtained:
Checking voltage supply
-
Turn the ignition switch ON
-
Using a multimeter, check the Oxygen Sensor (O2S) Behind Three Way Catalytic Converter (TWC) ( G130) electrical harness connector terminal
1 to engine ground.
Specified value: Battery voltage.
If the specified value was Not obtained:
-
Check the wiring for an open, high resistance, short circuit to each other, or Ground.
-
Check the electrical harness connector for damage, corrosion, loose or broken terminals.
-
If necessary, repair the faulty wiring connection.
If the specified value was obtained:
Checking Ground activation
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 Motronic Engine Control Module (ECM) ( J220). Refer to the Repair Information.
-
Using a multimeter, check the Oxygen Sensor (O2S) Behind Three Way Catalytic Converter (TWC) (G130) electrical harness connector terminal
2 to the Motronic Engine Control Module (ECM) (J220) electrical harness connector T121 terminal 6 for an open circuit according to the wiring
diagram.
Specified value: 1.5 ohms max.
If the specified value was Not obtained:
