-
Using a multimeter, measure the voltage of the Exhaust Pressure Sensor (G450/G451) harness connector terminal 1 to ground.
Specified value: near 5.01 V.
-
Using a multimeter, measure the voltage of the Exhaust Pressure Sensor (G450/G451) harness connector terminal 3 to ground.
Specified value: near 5.77 V.
-
Using a multimeter, measure the voltage of the Exhaust Pressure Sensor (G450/G451) harness connector terminal 2 to Battery Positive.
Specified value: Battery voltage.
-
Switch the ignition OFF.
If any of the specified values were Not obtained:
Checking wiring
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 Exhaust Pressure Sensor (G450) electrical harness connector to the Engine Control Module (ECM) (J623) electrical
harness T60 connector for resistance.
Specified value: 1.5 ohms Max.
If the specified value was Not obtained:
-
Check the wiring for a short circuit to each other, Battery positive, Ground or high resistance.
-
If necessary, repair the faulty wiring connection.
-
Check the electrical harness connector for damage, corrosion, loose or broken terminals.
If no malfunction is detected in the wiring and the voltage readings were Not correct:
-
Replace the Engine Control Module (ECM) (J623).
