Operating Condition

Start the engine. Hold the engine speed [ENGINE SPEED] at 3, 000 RPM without load (in P or N) until the radiator fan comes on.
Drive at a steady speed between 15 - 75 mph (25 - 120 km/h) for at least 15 minutes, and watch the long term fuel trim. If the long term fuel trim stays at about 1.0, the vehicle is OK or it is a very minor problem. If a significant fault is still present, the long term fuel trim will move up or down while driving.

When freeze data is stored, drive the vehicle under those conditions instead of Driving Pattern step 2.
After clearing the DTC by disconnecting the 12 volt battery or using the scan tool, drive at steady speed between 15 - 55 mph (25 - 90 km/h) for at least 40 minutes to allow time for long term fuel trim to recover.
Drive the vehicle in this manner only if the traffic regulations and ambient conditions allow.
