There are no true oxygen sensor cleaners that are safe to put through your engine. While some people choose to remove them and use a wire brush or an aerosol cleaner to remove deposits, we do not recommend trying to clean O2 sensors.
Can you clean an O2 sensor to make it work again?
A dirty oxygen sensor can cause your “check engine” light to come on, and can also result in your car burning through extra gasoline. If you suspect that your oxygen sensor may be dirty, you can clean it by first removing the sensor from its housing in the vehicle, and then soaking the sensor in gasoline overnight.Do oxygen sensors need cleaning?

What causes a oxygen sensor to fail?
O2 sensor failures can be caused by various contaminants that enter the exhaust. These include silicates from internal engine coolant leaks (due to a leaky head gasket or a crack in a cylinder wall or combustion chamber) and phosphorus from excessive oil consumption (due to worn rings or valve guides).Can you clean 02 sensors? Does cleaning oxygen sensors work?
Will fuel injector cleaner help O2 sensor?
Can I Just Clean My O2 Sensor? The short answer is that our strongest gasoline fuel additive, B-12 Chemtool Total Fuel System Clean-Up (part #2616), and a good tune-up might indirectly solve your problems.Can an O2 sensor fix itself?
Oxygen sensors are fairly easy to diagnose and replace. Typically, you cannot repair a faulty O2 sensor. It must be replaced because of the technology and materials in its housing.What causes carbon build up on O2 sensor?
Carbon buildup from a rich fuel mixture is a frequent occurrence and causes many sensors to go bad. There are many possible causes of this, including a clogged air filter or a leaking or defective fuel injector. Antifreeze can be very harmful to a sensor if it is allowed into the combustion chamber.What happens if I disconnect my O2 sensor?
When you remove the O2 sensor, your ECU is unable to calculate what fuel ought to be injected at a particular time. This will give your vehicle an ever-descending default value that automatically injects the same amount of fuel every time. Either your performance could be substandard or your fuel economy could be poor.Can you bypass O2 sensors?
Should You Bypass Oxygen Sensors? Bypassing the oxygen sensor with a dummy can be done. Many people will do this to get the Check Engine Light to turn off when emissions aren't right or to allow for more flexibility when tuning the engine.How long do O2 sensors last?
And lastly, how long do oxygen sensors typically last? Older vehicles have O2 sensors that will typically last 30,000 to 50,000 miles, or 3 to 5 years. Newer vehicles employ sensors with an additional heated element and these new sensors are more likely to last to 100,000 or 7-10 years.Can you clean O2 sensors with acetone?
I work with the "McGyver" of auto repair and he swears that he gets another year or two out of his O2 sensors (after he gets a OBD code to replace) by cleaning them in Acetone (!). He says that he swishes the sensor end around in Acetone for a minute or so, dries it w/compressed air and re-installs.What do you do with old O2 sensors?
O2/AF SENSOR RECYCLINGMany companies have realized the value of recycling scrap oxygen sensors over the years while some are reluctant to save and de-wire the sensors. The companies most attracted to recycling sensors are manufacturers, used converter recyclers, auto core recyclers and de-canners.
