Constructed from high quality material. The type of sensor is thimble and the thread diameter is 18mm. Features double protection layer, aluminum oxide trap layer, PTFE filter and stainless steel housing. Enter your vehicle model on the page can quickly find the results.
As long as the model is correct, it can be replaced directly, easy to install, save labor. If there is a quality issue, it can be replaced or refunded free of charge. Direct replacement - this oxygen sensor gasket is designed to match the fit and function of the original gasket on specified vehicles.
Restores functionality - this gasket is made to fit and fully restore part functionality after the original gasket fails. Durable construction - this part is made from quality materials to ensure reliable performance and long service life. It will be on the exhaust pipe leading from the motor toward the back of the vehicle. Most cars these days also have a second sensor behind the catalytic converter, which looks like a metal cylinder on the exhaust line and is found right behind the front wheels.
Each vehicle has 2 sensors near the motor and 2 near the catalytic converter. Disconnect the electrical connection to the oxygen sensor. Follow the cable away from the end of the sensor plugged into the exhaust line. It will end in a plastic plug inserted into an outlet. To remove it, locate the small tab on the end of the plug.
While pushing the tab down, pull the plug back by hand. Avoid attempting to cut and then solder the wires to the new oxygen sensor. With modern sensors, soldering causes the wires to stop working correctly. Spray some penetrating oil onto the sensor to loosen it. Worn-out sensors can be tough to remove, but 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 10 minutes for the oil to soak in before trying to unscrew the sensor.
You may need to apply the oil a few times before you are able to get the sensor out. Use a heat gun instead of a torch to lightly warm the sensor until you can remove it.
Unscrew the oxygen sensor using a ratchet wrench. Fit the wrench over the sensor where it plugs into the exhaust line. Turn it counterclockwise to loosen it, and then finish unscrewing it by hand. You could also check to see if your local auto parts stores has a tool rental program.
Apply more penetrating oil as needed to avoid damaging the vehicle. Part 3. Select a new oxygen sensor that is the same as the old one. Use the make and model of your car to find the correct oxygen sensor. For example, 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 as the old one. It should also be the same brand.
If you are able to, contact an auto parts store before attempting to change the sensor. You could also take the old sensor to a store if you can get a ride there. Add a small amount of anti-seize to the new sensor. New sensors come packed with a bag of bronze gel.
The threads are the grooves in the metal ring near the tip of the sensor. You 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. Turn 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 it is centered and goes in smoothly as you begin rotating it clockwise by hand. Once it is tightly in place, use an oxygen sensor socket or open end wrench to give it a final turn.
In fact, overtightening the sensor could strip the threads, making it impossible to remove! Plug the electrical connector back into the vehicle. The cable will be hanging from the free end of the sensor. Plug it into the outlet port close to the exhaust line. 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 better, runs more smoothly, and uses less fuel. If the check engine light was on, it most likely will turn off as well.
Take the car out on the road to make sure it stays off. Use the delete feature on an OBD code scanner to reset the light. Disconnect the battery or take the vehicle to a mechanic for additional ways to shut off the check engine light.
Hovig Manouchekian. New oxygen sensors often come with an anti-seizing or anti-corrosion lubricant that should be applied to the sensor when it's being installed. That will keep the threads on the sensor from seizing, which happens when temperatures fluctuate on the vehicle. Yes No. Not Helpful 2 Helpful 7. It should only take a few minutes depending on your experience level. Not Helpful 3 Helpful It will run, but poorly since the ECU won't know how efficient parts of the exhaust are.
It won't sound very good, and it won't run very well, so I don't recommend it. Not Helpful 2 Helpful It can be done in some cases without a special socket, but normally yes you should have the proper socket. Call your local NAPA store to be sure. Depending on the location of the sensor, the fuel delivery, and combustion systems can become extremely irregular by a bad O2 sensor.
If too much fuel is sent to the engine, it will cause gas mileage to suffer. Engine pinging. A bad O2 sensor can cause timing issues that will cause engine pinging. This occurs when the combustion gases ignite at the wrong time. Rough engine idle. When your Toyota has a bad O2 sensor, it will often idle irregularly or roughly.
