Checking Internal Resistance
-- Remove the right lower section of the intake manifold. Refer to LOWER INTAKE MANIFOLD WITH FUEL RAIL Removal and Installation.
-- Disconnect the Engine temperature control sensor -G694- electrical harness connector. -2-
-- Using a Multimeter, check the Engine temperature control sensor -G694- terminals 1 to 2 for resistance.
Specified value: 050Ω to 10K Ω
If the specified value was not obtained:
-- Replace the Engine temperature control sensor -G694-. Refer to appropriate Service Information.
-- Go to Final procedures.
If the specified value was obtained:
Checking Wiring
-- Remove the Engine Control Module -J623-. Refer to appropriate Service Information.
-- Using a Multimeter, check the Engine temperature control sensor -G694- 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 to Battery voltage 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 the 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 .
