Checking Wiring
-- Remove the Engine Control Module -J623-. Refer to appropriate service information.
-- Using a Multimeter, Check the Mass Airflow Sensor -G70- electrical harness connector to the Fuse for an open circuit, (Refer to applicable wiring diagram for fuse positions).
| Mass Airflow Sensor -G70- electrical harness connector terminals: | Engine Control Module -J623- electrical harness connector T94 terminal and Fuse, (Refer to applicable wiring diagram for fuse positions). |
|---|---|
| 3 | Fuse |
Specified value: 1.5 Ω Max.
If the specified value was Not obtained:
-- Check the wiring connection for an open or short circuit.
-- Check the wiring connection for damage, corrosion, loose or broken terminals.
-- If necessary, repair the faulty wiring connection and replace any open fuses
-- Go to Final Procedures
If the specified value was obtained:
-- Remove the Engine Control Module -J623-. Refer to appropriate service information.
-- Using a Multimeter, Check the Mass Airflow Sensor -G70- /Intake Air Temperature Sensor -G42- electrical harness connector to the Engine Control Module -J623- electrical harness connector for an open circuit.
