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 ?
