Q&A
Q:Why does the oxygen sensor have false alarm, after installation ?
A:The clearing of the errors can be obtained on most systems when the vehicle battery is disconnected for at least 60 seconds. The assignment of the new sensor parameters is done automatically when the errors are cleared, but in some systems a short adapting tour is required. In this case the vehicle has to be driven on the road for some 10-15 minutes, in order to have the ECU adapt itself to the new sensor.
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.
Q:How should I install oxygen sensor ?
A:The following is the installation instructions: Use the correct part number as listed in the application catalogue ,Do not use sensor if i has been dropped ,Remove protection cap just prior to installation;
Firstly install sensor body ensuring lead wire is not twisted or bent , Do not use impact wrench or socket type wrench to install sensor ,M18 sensors - install finger tight then 1/2-3/4 turn with a wrench (35-45Nm) ;
Then connect and route lead wire as originally installed , Do not allow lead wire to touch exhaust manifold or any other hot component ,Do not apply any substances (especially oil or grease) to connector sensor ,Do not use leaded fuels,silicone or metal based additives.
Q:When should replace the oxygen sensor?
A:Oxygen Sensor Failure Symptoms:
Reduced fuel mileage
Failed emissions testing
A check engine light
