Oxygen sensors are electronic devices installed in motor vehicles manufactured after 1980 to measure the ratio of oxygen in a car or truck's gasoline. When gasoline contains too little or too much oxygen, it is harmful to motor vehicles as well as the environment. In the case of too little oxygen, t
The typical signs of a faulty oxygen sensor include increased exhaust emissions due to poor air fuel mixture, engine hesitations, engine misfires, stalling, rough idling and increased fuel consumption. The oxygen sensor is a crucial component of a vehicle's electronic fuel injection and emission sys
Most newer engines have multiple oxygen sensors, and the location of each oxygen sensor is identified according to position and cylinder bank, according to AA1 Car. A diagnostic tool has the ability to identify the specific location of sensors experiencing malfunction issues.
Oxygen sensors in a car measure the amount of unburned oxygen present in the exhaust. They send the information to the car's computer, which adjusts the fuel-to-air ratio to ensure the highest fuel efficiency for the car while emitting the lowest amount of pollution, according to Smog Tips.
Depending on the type of car, it may have one or two oxygen sensors. On cars that have only one sensor, it is usually located near the exhaust manifold, but in cars with two oxygen sensors, the second sensor usually is found down from the catalytic converter.
To clean an oxygen sensor, lift the vehicle with a jack, and lubricate the sensor with oil. Use a wrench to remove the sensor, and soak the sensor in gasoline overnight. Dry the sensor, and reinstall it.
An oxygen sensor works like a generator and contains a bulb, which is coated in platinum and contains two strips of platinum that serve as electrodes. The oxygen sensor is placed in the exhaust manifold and is responsible for monitoring how much unburned oxygen is in the exhaust as it leaves the eng
The oxygen sensor is positioned inside in the exhaust pipe, and it is used to detect rich or lean mixtures. This sensor is an essential component in the emissions control system, and it transmits data to the engine's computer. The primary function of the oxygen sensor is to help the engine operate a
Virtually every vehicle manufactured since 1980 has an oxygen sensor, according to HowStuffWorks. Most cars on the road actually have between two and four sensors, according to John Nielsen, the director of engineering for the American Automobile Association, as reported in an article on Edmunds.com
While the most common oxygen sensor problem is the sensor itself failing, several other problems can cause a fault code in the onboard diagnostic computer that points to the sensor, including loose vacuum hoses and loose, broken or burned wires that lead to the unit. If the computer senses a problem
