Check your vehicle'southward owner'due south manual for the verbal locations of the sensors. All vehicles have at least two oxygen sensors: 1 in front of your car's catalytic converter, and ane in the motorcar'southward exhaust manifold.^[five] If your vehicle has more than one frazzle manifold, at that place will likely exist an oxygen sensor inside each one.

   • The oxygen sensor will look something like a spark plug: roughly two inches (5 cm) long. One end will have a hexagon shape—for a wrench to fit over—and the other end will be threaded to screw into your vehicle.
   • Make certain to let the vehicle cool off completely before you lot touch on the oxygen sensor—information technology'southward attached to the exhaust or muffler pipe, so if the pipage is hot, the sensor will exist, too.^[vi]

   Spray the sensors with WD-xl. As your vehicle's oxygen sensors are seldom removed, they will probably exist firmly stuck in identify. To loosen them, spray the sensors with a lubricant like WD-40 and let them sit for 10–15 minutes. The WD-xl will lubricate and loosen the sensors, making them easier to remove.^[seven]

   • If you don't already have a can of WD-40 around the firm, you lot tin can buy one at whatever local hardware or machine-supply store.

2. 2

   Fill a saucepan or industrial container with gasoline. While yous're waiting for the WD-40 to lubricate the spiral threads of the oxygen sensor, you tin start the side by side step of the process.

   • If y'all're purchasing the bucket or container at a hardware shop, enquire the sales staff to recommend a sealable, gasoline-safe plastic.

3. iii

   Unscrew the oxygen sensors from their housing. Y'all'll need to use a sturdy wrench for this. Each of the oxygen sensors should be well lubricated and loosened at this point; accept your wrench and firmly loosen the sensors.^[ix] As yous remove the sensors from your vehicle, exercise not ready them on the basis or allow them to become dingy. Place the sensors somewhere clean, such equally in a plastic basin or on a clean, flat spot on your vehicle.

   Immerse the sensors in a container of gasoline. In one case you have removed the oxygen sensors from your vehicle, submerge them in the bucket or industrial container that you've filled with gasoline. Given time, gasoline will make clean the oxygen sensors. Brand sure that the sensors are fully immersed in the gasoline, and that none of the liquid splashes out of the container or gets on your easily.^[10]

   • Never smoke, calorie-free a candle, or have whatsoever other type of open flame when working near gasoline.

2. ii

   Encompass the bucket with a lid. Due to the flammable nature of gasoline, it's important that you lot cover the bucket or industrial container of gasoline.

At some point while the sensors are soaking in the container of gas, pick the container up and swirl it around several times. This volition ensure that all parts of the sensors are being cleaned by the gasoline.^[12]

  Expert Answer

  Make sure you don't affect the oxygen sensor when the car is hot—the oxygen sensor is fastened to the exhaust pipe. I also recommend disconnecting the battery of the vehicle earlier removing any sort of electrical sensor. Besides, use WD40 or some sort of lubricant to help, because the expansion and wrinkle of the metal tin crusade the threading of the sensor to seize, which makes information technology very difficult to remove.

• Question

  Surely leaving the electrical contacts and wiring in gasoline for viii hours can't exist adept?

  

  Don't put that function in gas. only tape the wire to outside of bucket and then the sensor only is reaching the gas. The bucket is overkill; a 2-cup drinking glass measuring cup would be enough to clean two sensors.

• Question

  Tin I use whatsoever type of gasoline? Does it matter if it is special or regular?

  

  It doesn't matter. The octane rating should have nothing to do with it. Information technology'due south the compounds in the gasoline that practise the chore.

• Question

  Tin can I utilise mass airflow sensor cleaner to make clean my O2 sensor?

  

  Probably; it'south only electrical contact cleaner, after all. Petrol is cheaper and easily bachelor, and then that's likely why they recommend it.

• Question

  Can I put a pigsty in my catalytic converter to clean it?

  Can I utilise WD-40 to make clean oxygen sensors?

  

  WD-40 is oil based and might contaminate your sensor. Just use it to loosen the threads.

  How exercise I cheque if the sensor is working or non?

  

  The service manual should accept specifications for the resistance range between pins in the sensor's connector.

• Question

  Can I use kerosene instead of gasoline? Practise you lot call up information technology'due south improve for cleaning and less harmful?

  

  Tristan Rockwell

  Community Answer

  Kerosene is more likely to get out oily residuum on your sensors at normal temperature and pressure.

• Question

  Can I apply diesel fuel to make clean a catalytic converter?

  

  Scott Maziarz

  Community Answer

  No, diesel has oil in information technology and will contaminate the sensor. Use regular gas just, then completely dry the sensor with a material before reinstalling.

• Question

  What do I do if I changed the spark plugs in my vehicle and now information technology won't start?

  

  Check your firing lodge and gap. If y'all did them all at the same time, chances are the firing order could have been rearranged. Always bank check the gap of the plugs, too. Too, check for spark and check rotor button.

Article Summary X

Earlier you can make clean an oxygen sensor, you have to remove information technology from the exhaust manifold. To make this easier, spray the sensor with WD40 and permit it sit for fifteen minutes. In one case the sensor is loose, unscrew information technology and allow it soak in a container of gasoline for at least 8 hours. When you exercise this, prevent leaks and fires by making certain the container is gasoline resistant and by covering it with a lid. After they've soaked, dry the sensors off and re-install them. Proceed reading to larn how to notice the oxygen sensors.
