The first indication of a problem with your vehicle's oxygen sensor is frequently when the "check engine" light comes on. Failing sensors crusade jerky movements, trouble starting, and reduced fuel efficiency if they aren't replaced. Oxygen sensors are necessary for vehicles to combine the proper ratio of gas and oxygen into fuel. Depending on the make and model, your vehicle could accept 2 to 4 of them to replace. Even if you have minimal experience with cars, they aren't hard to replace. Twist off the sometime sensors, install the new ones, and then appreciate how much better your vehicle runs.

1. 1

   Utilize an OBD lawmaking scanner to detect the cleaved sensor. An OBD code scanner is a device that plugs into a port on the car'south dashboard. It retrieves an fault lawmaking from the onboard computer, which shows you the reason for the cheque engine low-cal. Each error code corresponds to a different office of the vehicle. To effigy out which sensor is to blame, blazon the code into an online database like http://world wide web.obdii.com/codes.asp.

   • You tin purchase a scanner online or at most auto parts stores. If you lot don't have ane, you could take your vehicle to an auto parts shop or mechanic to have them discover the fault lawmaking.

2. two

   Let the engine cool before attempting to remove a sensor. The sensors are located along the exhaust system, which gets very hot when the vehicle is in utilize. Touching the engine, for instance, is unsafe. Turn the vehicle off and give it about 30 minutes to cool.^[1] If y'all demand to touch a component before yous are sure it is cool, habiliment protective gear.

   • Have a heat-resistant glove, such as a welder'due south mitt. Besides, put on long-sleeved clothing and safety glasses for additional protection.

3. 3

   Jack upwardly the vehicle if you need to accomplish a sensor under it. Park the automobile on a difficult, flat surface. Preclude the wheels from moving by wedging chocks backside them. Then, slide a jack underneath ane of the vehicle's jack points. After lifting it up, place a jack stand at that place to keep the motorcar elevated.

   • Starting around 1994 and 1995, manufacturers started making vehicles with 2 oxygen sensors. The second sensor is but attainable past itch underneath the vehicle.
   • Lifting a car is dangerous, then make sure it is stable before looking for the sensor. If yous aren't comfortable working under a machine, ask a mechanic for assistance.

1. ane

   Locate the oxygen sensor underneath the hood or vehicle. Wait for a role that looks like a spark plug with a thick, black cable coming out of it. The kickoff sensor volition always be side by side to the motor in the engine compartment. It will be on the exhaust pipe leading from the motor toward the dorsum of the vehicle. Most cars these days likewise accept a 2d sensor behind the catalytic converter, which looks like a metal cylinder on the frazzle line and is plant correct behind the front wheels.^[two]

   • Nigh vehicles made after the year 2000 actually take 4 sensors. Each vehicle has ii sensors nigh the motor and 2 near the catalytic converter.

2. 2

   Disconnect the electrical connectedness to the oxygen sensor. Follow the cablevision away from the end of the sensor plugged into the exhaust line. It will terminate in a plastic plug inserted into an outlet. To remove it, locate the pocket-size tab on the end of the plug. While pushing the tab downwardly, pull the plug back by paw.^[3]

   • If you lot're having a hard time unplugging the sensor wire, push the tab down with a flathead screwdriver as yous pull the connectedness dorsum with your gratuitous paw.
   • Avoid attempting to cut and and then solder the wires to the new oxygen sensor. With modern sensors, soldering causes the wires to terminate working correctly.

3. three

   Spray some penetrating oil onto the sensor to loosen it. Worn-out sensors tin be tough to remove, merely a good penetrating oil helps ensure they come out. Add the lubricant to the opening where the sensor plugs into the exhaust line. Wait about ten minutes for the oil to soak in before trying to unscrew the sensor. You may need to use the oil a few times before you are able to become the sensor out.^{[4] [v]}

   • Some other way to treat a stubborn oxygen sensor is to rut upward its base and threads. Use a estrus gun instead of a torch to lightly warm the sensor until y'all tin can remove it. A heat gun doesn't have flames, so it'southward safer than a torch, but be careful and protect yourself with proper condom gear.

4. iv

   Unscrew the oxygen sensor using a ratchet wrench. The easiest fashion to detach the sensor is by using a ^three⁄₈  in (0.95 cm) ratchet wrench fit with a ^vii⁄_eight  in (ii.2 cm) oxygen sensor socket. If you don't have one, try using an open end wrench. Fit the wrench over the sensor where it plugs into the frazzle line. Plough information technology counterclockwise to loosen information technology, and so end unscrewing it by manus.^[vi]

   • All of the tools y'all need are available online or at well-nigh auto parts stores. You lot could also check to see if your local automobile parts stores has a tool rental plan.
   • If the sensor feels stuck in place, don't force it. Apply more penetrating oil equally needed to avoid damaging the vehicle. If information technology's likewise tough to remove, accept it to a professional person.

1. 1

   Select a new oxygen sensor that is the same equally the sometime one. Employ the make and model of your car to find the correct oxygen sensor. For instance, search for a Toyota Prius to find the exact sensor used in a new Prius. Make sure the new sensor is the same size and shape equally the old one. Information technology should too exist the same brand.^[7]

   • You may find off-brand sensors at a cheaper charge per unit, but avoid them for the sake of your vehicle. The only sensor model guaranteed to piece of work with the vehicle's onboard computer is the same one the manufacturer used.
   • If you are able to, contact an motorcar parts store before attempting to change the sensor. You could as well have the old sensor to a store if yous can become a ride at that place.

2. 2

   Add a modest amount of anti-seize to the new sensor. New sensors come up packed with a purse of bronze gel. You may be wondering what that strange goo is at first, but information technology's a very important lubricant. Cutting open the pocketbook, then use a glove or clean rag to spread a small-scale amount of the lubricant onto the new sensor'south threads. The threads are the grooves in the metal ring near the tip of the sensor.^{[8] [9]}

   • To avoid any problems with the anti-seize, wear a glove when applying it by hand. If yous get it on your skin, information technology isn't likely to impairment y'all, but thoroughly wash your hands afterward.
   • You lot do not need a lot of the gel. As long as you get some of it into the thread grooves, the sensor will fit properly in the exhaust line.

3. 3

   Plough the sensor clockwise to secure it on the exhaust line. Fit the tip of the sensor into the hole on the exhaust line. Make sure information technology is centered and goes in smoothly equally yous begin rotating it clockwise by hand. Once information technology is tightly in place, use an oxygen sensor socket or open finish wrench to give it a final plough.^[10]

   • The new sensor doesn't accept to be tightened equally much as possible. In fact, overtightening the sensor could strip the threads, making information technology impossible to remove!

4. 4

   Plug the electrical connector dorsum into the vehicle. Modern oxygen sensors come equipped with a connected electrical cable, so yous don't have to practice any boosted work. The cable will be hanging from the costless terminate of the sensor. Plug it into the outlet port shut to the exhaust line.^[11]

   • Push button the plug in until it snaps into place. Make certain the cable isn't touching the engine or other parts that oestrus up when the vehicle is in use.

5. 5

   Start the car to see if the problem is fixed. The new sensor makes a big difference. It causes your vehicle to burn fuel more efficiently, It sounds meliorate, runs more smoothly, and uses less fuel. If the check engine lite was on, information technology virtually probable will turn off likewise. Take the car out on the route to make certain it stays off.^[12]

   • In some vehicles, you may demand to clear the check engine light manually. Shut off the engine, then turn the machine'due south power on using the ignition cardinal. Use the delete characteristic on an OBD code scanner to reset the lite.
   • Disconnect the battery or take the vehicle to a mechanic for additional means to close off the check engine light.
   • If the check engine light comes back on, either the oxygen sensor wasn't installed correctly or your vehicle has another problem.

  Proficient Answer

  New oxygen sensors often come with an anti-seizing or anti-corrosion lubricant that should be applied to the sensor when information technology's being installed. That will go on the threads on the sensor from seizing, which happens when temperatures fluctuate on the vehicle.

• Question

  How long does it take to replace an O2 sensor?

  

  Information technology should but take a few minutes depending on your experience level.

• Question

  Will a vehicle run without sensors?

  

  Information technology will run, but poorly since the ECU won't know how efficient parts of the exhaust are. Information technology won't sound very skillful, and it won't run very well, so I don't recommend it.

• Question

  Practice I need to use a special socket when changing an oxygen sensor?

  

  Information technology can exist washed in some cases without a special socket, but commonly yep you should have the proper socket. Call your local NAPA store to be sure.

• Question

  How many o2 sensors are in my car?

  

  William Gregory Lawler

  Customs Reply

  It depends on your exhaust system. Probably just two, but information technology could be four if you lot have dual exhaust. They are always 1 in forepart of the catalytic converter (the skinny muffler looking affair in the frazzle line close to the engine), and the second just downstream from the cat. They are ordinarily rated as S11, S12, S21, and S22 which are designations for bank and front or back. For example, S11 would be bank ane (which is the #1 plug side for V-type engines) front.

• Question

  Practise I demand to disconnect the battery when changing out the O2 sensor?

  

  No, there is no need to disconnect the bombardment when replacing O2 sensors.

• Question

  How practice I locate the oxygen sensor nether the hood?

  

  It is not under the hood. Look for a spark plug-looking part with a wire coming out of it somewhere along your exhaust pipe system. Y'all may have more than 1. Unplug the wire at the connector and remove O2 sensor. They do sell a special tool, only y'all tin do it with a crescent wrench. Utilize some liquid wrench first. Apply anti-seize to the threads of the new O2 sensor for ease of installation and reconnect the wire.

• Question

  Can my vehicle accept but 1 oxygen sensor?

  

  No, this is not possible. There are always a minimal of ii oxygen sensors to compare values to the ECU.

• Question

  With 133,000 miles on my car, should I replace the less expensive oxygen sensor(southward) offset, and then run into if I need to supplant the catalytic converter?

  

  You should replace it all at one time. The oxygen sensors will brand certain that your auto has plenty of oxygen and won't suffocate and, for that reason, it'southward important to supersede all your oxygen sensors.

• Question

  How practice I locate left bank, correct bank and numbered sensors on a Suzuki XL7?

  

  Left banking company is the left side of the engine, and right bank would be the right side of the engine as you lot sit in the car looking out. The sensors would be called upstream and downstream, with upstream being closest to the front and downstream being towards the back of the car.
