Observe all safety precautions: SAFETY PRECAUTIONS .

View clean working conditions: CLEAN WORKING CONDITIONS .

Use only gold-plated terminals when servicing any component with gold-plated electrical harness connector terminals.

For wiring diagrams, component locations, and connector views, Refer to the appropriate System Wiring Diagram.

Special tools and workshop equipment required 

• multimeter
• Wiring diagram.

Test requirements

• The Engine Control Module - 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 (GND) 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 covers. Refer to the appropriate Service Information.

-- Switch the ignition ON.

-- Disconnect the Intake Manifold Runner Position Sensor 2 -G512- electrical harness connector -1-.

-- Switch the ignition ON.

-- Using a Multimeter, check the Intake Manifold Runner Position Sensor 2 -G512- electrical harness connector terminals 1 to 3 for voltage.

Specified value: about 5.0 V.

-- Switch ignition OFF.

If the specified value was Not obtained:

-- Check the wiring connection for an open circuit.

-- Check the wiring connection for damage, corrosion, loose or broken terminals.

-- If necessary, repair the faulty wiring connection.

-- Go to Final procedures.

If the specified value was obtained:

Checking internal resistance 

-- Using a Multimeter, check the Intake Manifold Runner Position Sensor 2 -G512- electrical terminals 2 to 3 for resistance.

Specified value: 7-25 Ω (at Approx. 20° C).

-- Using a Multimeter, check the Intake Manifold Runner Position Sensor 2 -G512- electrical terminals 1 to 3 for resistance.

Specified value: 244 [+/- 40] Ω (at Approx. 20° C).

-- Go to Final procedures.

If the specified value was Not obtained:

-- Replace the Intake Manifold Runner Position Sensor 2 -G512-. Refer to appropriate Service Information.

-- 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 Intake Manifold Runner Position Sensor 2 -G512- electrical harness connector terminals to the Engine Control Module -J623- electrical harness connector T94 terminals for an open circuit.

Intake Manifold Runner Position Sensor 2 -G512- electrical harness connector terminals:	Engine Control Module -J623- electrical connector T94 terminals:
2	13

Specified value: 1.5 Ω Max.

If the specified value was Not obtained:

-- Check the wiring for a short circuit, or an open circuit.

-- Check the electrical harness connector for damage, corrosion, loose or broken terminals.

-- If necessary, repair the faulty wiring connection.

-- Go to Final procedures.

If the specified value was obtained:

-- Replace the Engine Control Module -J623-. Refer to appropriate Service Information.

-- Install the engine cover with air filter. Refer to appropriate Service Information.

Final procedures 

-- Reinstall the engine cover with air filter, if necessary. Refer to the appropriate Service Information.

-- After the repair work, the following work steps must be performed in the following sequence:

1. Check the DTC memory. Refer to DIAGNOSTIC MODE 03 - READ DTC MEMORY .
2. If necessary, erase the DTC memory. Refer to DIAGNOSTIC MODE 04 - ERASE DTC MEMORY .
3. If the DTC memory was erased, generate readiness code. Refer to READINESS CODE .
