SERVICE INFORMATION
All Models, 02 Sensor DTCs
In the event you have a vehicle with O2 sensor DTCs, do not replace the O2 sensor without checking the entire system. If the O2 sensor DTC is accompanied with other DTCs such as fuel trim, check the fuel trim first. A fuel trim problem can cause O2 sensor DTCs and should be repaired first.
