Do lambda sensors need to be cleaned?

An Oxygen Sensor is a high-precision electrochemical sensor that usually does not need to be cleaned but replaced. If you suspect a problem with the oxygen sensor, the following tests are recommended:

Observe if the vehicle's driving performance deteriorates: If you notice an increase in fuel consumption or a decrease in driving performance, this may be a sign of a problem with the oxygen sensor.

Check if the Engine Fault Indicator (MIL) is lit: If there is a problem with the oxygen sensor, the ECU may detect an abnormality and light the engine fault indicator.Fault code scanning: If you suspect a problem with your oxygen sensor, you can perform a fault code scan with your car diagnostic tool to determine if the fault code is related to the oxygen sensor.

Check the appearance of the oxygen sensor: If the oxygen sensor is contaminated or damaged, it may cause it to fail. You can check the appearance of the oxygen sensor for damage or corrosion.

Please note that cleaning the oxygen sensor may cause its electrochemical performance to decrease or fail, so cleaning the oxygen sensor is not recommended. If you suspect a problem with the oxygen sensor, it is recommended to choose original parts or high-quality replacement parts that match the vehicle, and ask a professional technician to replace and debug.
