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
- 8 - Intake manifold.
- 9 - Intake manifold flap motor.
- 12 - Intake manifold runner position sensor.
Voltage check
-- 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-. Refer to the Repair information.
If the specified value was Not obtained:
Checking wiring
-- Remove the Engine Control Module (ECM) -J623-. Refer to the Repair information.
-- 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 T60 terminals for an open circuit.
| Intake Manifold Runner Position Sensor - G336- electrical harness connector terminals: | Engine Control Module (ECM) -J623- electrical connector T60 terminals: |
|---|---|
| 1 | 27 |
| 2 | 59 |
| 3 | 13 |
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 found in wiring and the voltage check was Not OK:
-- Replace the Engine Control Module (ECM) -J623-. Refer to the Repair information.
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 .
