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.
- The following information is for instructional and guidance reference only. We try and make them as accurate as we can.
- If Check Engine Light is on or an OBDII Trouble/Fault code occurs after installation, check the sensor with a voltmeter as below. If the sensor is good, further diagnosis is required. There're many different codes for specific functional failures, which are NOT necessarily relevant to the sensor. Find out what the Code means before leaving any feedbacks.
- Items that have been installed, altered or contaminated are non-returnable. ONLY a defective sensor after tested by a voltmeter is applied to manufacturer warranty.
- 20% restocking fee is required if buyer bought wrong items due to not paying attention to fitment information and ask for return.
- The Price, Quality & Funcitonality of the O2 Sensor is fully covered under our warranty & return policy. However, refund for any labor cost, expense in a dealer shop or damage due to wrong installation is NOT covered.
Q: How do I know the O2 sensor is good or not? (Online Video)
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.
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.
