Timely Replacement Of Vehicle Oxygen Sensor Is Very Important!

Improve Fuel Economy

When the oxygen sensor detects incomplete fuel combustion, it reduces the amount of fuel injected, making fuel more economical for fuel performance.

Reduce Exhaust

Ensure that the ternary catalytic converter has conversion efficiency for hydrocarbon, carbon monoxide and nitrogen oxides in the exhaust, and carry out the conversion and purification of pollutants discharged.

Improve Engine Performance

Ensure the engine receives the correct air/fuel mixture, thus preventing the engine from running thin or rich to ensure efficient engine operation.

Improve Engine Idle Stability

Eliminate engine idle speed instability, steering wheel shake,and let the vehicle safer driving.

Warm Prompt

When you install the new oxygen sensor, keep the car running as long as possible to get the sensor used to your car. If the oxygen sensor failure light comes on soon after the oxygen sensor is replaced, you must check for carbon pollution, clean the inlet and combustion chamber, and check other related accessories.

Remove And Install Instructions

Identify the fault sensor from the dashboard error.Disconnect the faulty oxygen sensor.Remove the oxygen sensor with tools. (Ratchet, socket or wrench)Compare the original and replacement oxygen sensors, especially the plug must be exactly the same.Attach the new oxygen sensor to the vehicle, connect the harness and plug it in.Clear the fault code and start the car.
