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.
-- If necessary, repair the faulty wiring connection.
-- Check the electrical harness connector for damage, corrosion, loose or broken terminals.
If no fault is detected in the wiring and the voltage supply was OK:
-- Replace the Throttle Valve Control Module -J338-. Refer to the Repair Information.
If no fault is detected in the wiring and the voltage supply was Not OK:
-- Replace the Engine Control Module (ECM) -J623-. Refer to the Repair Information.
