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 applicable wiring diagram.

Special tools and workshop equipment required 

• multimeter.
• Wiring diagram.

Test requirements

• The ignition switched off.

Test procedure

-- Perform a preliminary check to verify the customers complaint. Refer to PRELIMINARY CHECK 

Start diagnosis

Make sure the engine is at room temperature.

-- Disconnect the malfunctioning sensor Intake Manifold Runner Position Sensor -G336- electrical harness connector.

-- Switch the ignition ON.

-- Using a Multimeter, Check the Intake Manifold Runner Position Sensor -G336- / Intake Flap Motor -V157- electrical harness connector terminals 1 to 3 for voltage.

Specified value: about 5.0 V

-- Switch the ignition Off.

Continue test according to the following table:

Value	Cause	Test
If the specified value was not obtained:	Open or shorted circuit	Refer to Intake Flap Motor -V157- AND Intake Manifold Runner Position Sensor -G336-, CHECKING =>
If the specified value was obtained:	Check reference signal circuit	Refer to Intake Flap Motor -V157- AND Intake Manifold Runner Position Sensor -G336-, CHECKING =>

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- / Intake Flap Motor -V157- electrical harness connector to the Engine Control Module (ECM) - J623 - electrical harness connector T60 for an open circuit.

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 the specified value was obtained:

-- Replace the Engine Control Module (ECM) -J623-. Refer to the Repair Information.

Final procedures

-- Install the engine cover. Refer to the Repair 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 .
