SERVICE INFORMATION
All models - Oxygen sensor fault codes
In the presence of the oxygen sensor-related fault codes, do not replace the sensor, first check the entire system. If the oxygen sensor fault code is accompanied by a related code in the fuel metering, first check the fuel metering. The problems of fuel metering can lead to the registration of an oxygen sensor fault code and must be repaired first.
