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.

Q: How do I know the O2 sensor is good or not?

A: The only way to know if the O2 sensor is functioning normally is to check its responsiveness to changes in the air/fuel mixture, by Voltage Measurement or Waveform Simulation.

Use a 10-megaohm digital voltmeter. Hook up the voltmeter's red probe to the sensor's signal wire and the black probe to engine ground. (Use back probe method, DO NOT pierce the wire.) For a good sensor, voltage should fluctuate constantly between 0.1 and 0.9 volts after starting the engine for 2 or 3 minutes.
