Please check OEM number before purchasing. 2. Please allow 1-3cm error due to manual measurement. Thanks for your understanding. 3. Monitors are not calibrated same, item color displayed in photos may be showing slightly different from the real object. Please take the real one as standard. Must Know Before Buying: 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. Position confirmation: Upstream sensor is before the catalytic(cat.) converter. Downstream sensor is after the catalytic converter. Upstream oxygen sensor is also known as sensor 1, or pre-cat, or upper oxygen sensor. Downstream oxygen sensor is also known as sensor 2, or post-cat, or lower oxygen sensor. When should we replace the oxygen sensor : How to replace the oxygen sensor : Step 1 - Some sensors are equipped with a heat shield that must be removed before the sensor removal, this is performed by removing any mounting bolts. Step 2 - By using a regular socket it minimizes potential damage to the sensor body and the threads, this technique helps avoid stripping the old sensor upon removal. Step 3 - Then, locate and disconnect the wiring connector, this step should be done before removing the sensor if the wiring is still attached. Step 4 - Its important that the wiring harness connectors are exactly the same, each sensor is unique to it's position and is located in the system by its connector configuration. (Note: some replacement sensors have a universal electrical connector that must be configured to the wiring of the old sensor.) Step 5 - Use a small wire brush to help clean the threaded port to ensure a proper seal of the new sensor. Gently install the new oxygen sensor by hand while keeping the wiring and connector free from bends. Step 6 - Gently tighten the sensor while keeping wiring free from damage, these sensors need to be fairly snug to avoid leakage. Step 7 - Once the sensor is tightened, reinstall any heat shields or bracing that had to be removed. Step 8 - After the heat shield has been reinstalled, mount the connector to it's holder and reattach the connector back onto the wiring harness. If the car has diagnostic trouble codes, they will need to be cleared. 1.Our Working Time:(GMT+8)Monday to Saturday,8:00-18:00. 2.For inquires and customer support, please send your email to us.All emails will be responded to within 24 hours during business days. 3.Parts Information: Before purchase this parts, please check the compatibility information and verify the correct OEM part number.
