If your car’s oxygen sensor is defective, it can cause the car to fail a emissions test. In this article, we’ll show you how to check the oxygen sensor in your car and how to replace it if necessary.
What is the Oxygen Sensor?
The oxygen sensor is a device located on the exhaust system of most vehicles. It monitors the amount of air pollution and converts that information into a signal that is sent to the fuel injection system. If the oxygen sensor detects too much air pollution, it will send a signal to the fuel injection system to decrease the amount of fuel being injected into the engine. This will help reduce emissions from the vehicle.
How to Check an Oxygen Sensor in a Car
If you own an older car, it’s likely that the oxygen sensor is located near the exhaust pipe. In cars with newer engines, the sensor is most likely located near the catalytic converter.
To check an oxygen sensor in a car:
1. Park your car in a level place and turn off the engine.
2. Open the hood and locate the exhaust pipe.
3. If your car has a newer engine, locate the catalytic converter next to the exhaust pipe. If your car has an older engine, locate the oxygen sensor near the exhaust pipe.
4. Loosen or remove the clamp that holds the oxygen sensor in place.
5. Gently pull up on the sensor until it comes out of its holder.
6. Check for any abnormal readings on the sensor and replace it if necessary.
What to Do If Your Oxygen Sensor is Broken

One option is to take your car to a mechanic. However, if you’re feeling lucky, you could try to fix the sensor yourself. To do this, you’ll need a replacement oxygen sensor, a voltmeter, and a few other tools. Here’s how to do it:
1. Remove the air filter housing. It’s held in place by 10 Torx screws.
2. Disconnect the battery cable and the negative terminal of the battery.
3. Remove the air intake hose from the air cleaner box.
4. Remove the eight bolts that hold down the air cleaner box cover.
5. Lift off the cover and remove the broken oxygen sensor. If there’s more than one broken sensor, replace them all.
6. Clean all of the parts thoroughly with a degreaser and water before reassembling in reverse order. Be sure to torque all of the
