Diagnostic Trouble Codes (DTC)
When oxygen sensor failure occurs, a DTC is recorded in the Engine Control Unit (ECU) and a Malfunction Indicator Lamp (MIL) is illuminated on the dash, alerting the driver the vehicle has a problem.
How to replace an oxygen sensor?
1- Disconnect the battery.
2- Locate the sensor connector by following its wires. Disconnect it.?
3- Remove the sensor cable from its clips all along its way to the sensor.
4- A specific 22mm socket with side cut out exists (see below). You can use a spanner instead. Hold it in one hand and give it a firm hit with the other hand. It will then unscrew very easily.
5- Remove the sensor and fit the new one.
6- Re-route the cable carefully and meticulously and fix it at every clip. Reconnect the connector.
7- Reconnect the battery and wait 5 minutes before starting the engine.
