Confirmation Procedure

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.
