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.
-- Disconnect the Intake Manifold Runner Position Sensor -G336- electrical harness connector -1-.
-- 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: 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 -G336- 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 -G336- 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 -G336-. 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 -G336- electrical harness connector terminals to the Engine Control Module -J623- electrical harness connector T94 terminals for an open circuit.

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.
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:
- 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 .
