Identify the oxygen sensor(s). Depending on the make and model of your vehicle, it may accept more than one oxygen sensor. Check your vehicle's owner's manual for the exact locations of the sensors. All vehicles have at to the lowest degree two oxygen sensors: i in front of your motorcar's catalytic converter, and one in the machine's exhaust manifold.^[v] If your vehicle has more ane frazzle manifold, at that place volition likely be an oxygen sensor within each one.
- The oxygen sensor will look something like a spark plug: roughly two inches (5 cm) long. 1 stop will have a hexagon shape—for a wrench to fit over—and the other end volition be threaded to screw into your vehicle.
- Make certain to let the vehicle absurd off completely before you touch on the oxygen sensor—it's attached to the exhaust or muffler pipe, and so if the pipage is hot, the sensor will be, besides.^[6]

Spray the sensors with WD-twoscore. As your vehicle'southward oxygen sensors are seldom removed, they will probably be firmly stuck in place. To loosen them, spray the sensors with a lubricant like WD-40 and let them sit for 10–15 minutes. The WD-40 volition lubricate and loosen the sensors, making them easier to remove.^[7]
- If you don't already accept a can of WD-40 effectually the house, yous can purchase one at any local hardware or automobile-supply store.
2
Fill a saucepan or industrial container with gasoline. While you're waiting for the WD-40 to lubricate the spiral threads of the oxygen sensor, you tin can start the side by side pace of the process. Make full a large bucket or industrial plastic container with gasoline, and set this about your vehicle. One time yous accept removed the oxygen sensors from your machine, you'll make clean them by soaking them in the gasoline.^[viii]
- Make sure that the bucket or container that you choose tin can safely contain gasoline. Not all types of containers volition exist gasoline resistant.
- If y'all're purchasing the bucket or container at a hardware store, ask the sales staff to recommend a sealable, gasoline-safe plastic.
iii
Unscrew the oxygen sensors from their housing. You lot'll need to use a sturdy wrench for this. Each of the oxygen sensors should be well lubricated and loosened at this bespeak; take your wrench and firmly loosen the sensors.^[9] Every bit yous remove the sensors from your vehicle, do not prepare them on the basis or permit them to become dirty.

Immerse the sensors in a container of gasoline. In one case you lot have removed the oxygen sensors from your vehicle, submerge them in the bucket or industrial container that you lot've filled with gasoline. Given fourth dimension, gasoline will clean the oxygen sensors. Make 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 hands.^[10]
- Never fume, light a candle, or have any other type of open flame when working most gasoline.

Cover the saucepan with a lid. Due to the combustible nature of gasoline, it's important that you encompass the bucket or industrial container of gasoline. This will prevent the gas from catching burn, and likewise go on any wandering animals from accessing the gas. If the industrial container came with a lid, you can utilize this to embrace the gas.^[11] Make certain to seal the lid tightly.
- If you're soaking the sensors in a bucket or a container that does not have its ain lid, you'll need to discover something to cover the opening with. Await for an appropriately sized lid among your pots and pans in the kitchen, or simply place a piece of plywood or a large book over the bucket opening.

Allow the sensors to soak overnight. The gas won't clean the oxygen sensors immediately; you'll need to let them soak for at least viii hours. At some point while the sensors are soaking in the container of gas, pick the container up and swirl information technology around several times. This will ensure that all parts of the sensors are beingness cleaned past the gasoline.^[12]

Remove and dry out the sensors. After the sensors have soaked overnight, you'll need to attain into the saucepan or container of gasoline and remove the sensors. Annotation their appearance: they should be much cleaner than when you put them in. And then, using a clean cotton wool cloth, wipe the gasoline off of the oxygen sensors and dry them fully.^[13]

Make sure you don't touch the oxygen sensor when the car is hot—the oxygen sensor is attached to the exhaust piping. I likewise recommend disconnecting the battery of the vehicle earlier removing any sort of electrical sensor. Also, use WD40 or some sort of lubricant to help, because the expansion and contraction of the metallic can cause 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 8 hours tin can't exist skilful?

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

Can I use whatever type of gasoline? Does it matter if it is special or regular?

It doesn't matter. The octane rating should have zippo to do with it. It's the compounds in the gasoline that do the job.
Question

Can I use mass airflow sensor cleaner to make clean my O2 sensor?

Kerosene is more likely to exit oily balance on your sensors at normal temperature and pressure level.

Check your firing social club and gap. If you lot did them all at the aforementioned time, chances are the firing order could have been rearranged. E'er check the gap of the plugs, also. Likewise, check for spark and cheque rotor push button.
