    Where are my oxygen sensors located?

     

     

    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. 

     

                   

                   

            

     

     

    Please take a video clip of the voltmeter and contact us if our sensor:

     

    Goes above range between 0.1 and 0.9 volt
    Remains below 0.5 volts
    Stays fixed at a particular voltage
    You're free to choose replacement or refund if our sensor fails to work, in this case.
