Confirmation Procedure
1. Hold the engine speed at 3000 RPM without load (in P or N) until the radiator fan comes on, then let it idle for 2 minutes.
2. Confirm and record the HDS [ ECT Sensor 1 ] value, then turn the vehicle to the OFF (LOCK) mode.
3. Open the hood, and let the engine cool for 3 hours.
4. Turn the vehicle to the ON mode, and confirm the HDS [ ECT Sensor 1 ].
NOTE:
If the HDS [ ECT Sensor 1 ] value changes less than 18 deg.F (10 deg.C), the failure is duplicated.
