Intake Manifold Runner Position Sensor, Checking
Special tools and workshop equipment required
- Multimeter.
- Wiring diagram.
Test requirements
- The Engine Control Module (ECM) - J623- fuses OK.
- Battery voltage at least 12.5 volts.
- All electrical consumers such as, lights and rear window defroster, switched off.
- Vehicles with automatic transmission, shift selector lever into position "P" or "N".
- A/C switched off.
- Ground connections between engine/transmission/chassis OK.
- Ignition switched Off.
Test procedure
-- Perform a preliminary check to verify the customers complaint. Refer to PRELIMINARY CHECK
Start diagnosis
-- Remove the engine cover with air filter.
-- Disconnect the Intake Manifold Runner Position Sensor -G336- electrical harness connector.
-- Switch the ignition On.
-- Using a multimeter, check the Intake Manifold Runner Position Sensor -G336- electrical harness connector terminals 1 to 3 for voltage.
Specified value: near 5 V
-- Switch ignition Off.
If the specified value was obtained:
-- Replace the Intake Manifold Runner Position Sensor - G336-.
If the specified value was Not obtained:
Checking wiring
-- Remove the Engine Control Module (ECM) -J623-.
-- Using a multimeter, check the Intake Manifold Runner Position Sensor - G336- electrical harness connector terminals to the Engine Control Module (ECM) -J623- electrical harness connector T105 terminals for an open circuit.
| Intake Manifold Runner Position Sensor - G336- electrical harness connector terminals: | Engine Control Module (ECM) -J623- electrical connector T105 terminals: |
|---|---|
| 1 | 48 |
| 2 | 36 |
| 3 | 47 |
Specified value: 1.5 Ω Max.
If the specified value was Not obtained:
-- Check the wiring for an open, high resistance or short to ground.
-- Check the electrical harness connector for damage, corrosion, loose or broken terminals.
-- If necessary, repair the faulty wiring connection.
If no malfunction is detected in the wiring and the voltage was Not present:
-- Replace the Engine Control Module (ECM) -J623-.
-- Install the engine cover with air filter.
Final procedures
After the repair work, the following work steps must be performed in the following sequence:
- Check the DTC memory. Refer to DIAGNOSTIC MODE 03 - READ DTC MEMORY .
- If necessary, erase the DTC memory. Refer to DIAGNOSTIC MODE 04 - ERASE DTC MEMORY .
- If the DTC memory was erased, generate readiness code. Refer to READINESS CODE .
