Follow the exhaust back, in the exhaust there should be spark plug looking sensors with a smaller single wire coming out the top, these are your oxygen sensors. Depending on year there can be one to four sensors on your auto.
A faulty oxygen sensor can make a car smell like gas. Oxygen and gasoline mixing wrong can cause excessive pollution. Replacing the oxygen sensor can correct this issue, and improve the gas mileage in the car.
the oxygen sensor is located in/on the exhaust manifold.it looks like a spark plug with a wire coming out of the top
Bank 2 sensor 2 refers to the oxygen sensor on the passenger side of the exhaust system and after the catalytic converter. heater circuit is the oxygen sensor or the wiring going to it, it is what is called a heated oxygen sensor. Google image search oxygen sensor and that is what it looks like, and they can be a bear to get out.
The oxygen sensor on any vehicle is located on under the car on the top of the muffler pipe just behind the cadallidic converter....do you know what the oxygen sensor looks like so you know what you're looking for?
The outward appearance of a defective oxygen sensor is no different than the appearance of a brand new one. The components that fail are internal and cannot be repaired ... direct replacement is the only fix.
i would like a wiring diagram for a Honda civic o2 sensor
It means the bank 1 oxygen sensor is not switching like it should. Sometimes this means the sensor is bad, sometimes it means the MAF sensor is dirty. If the oxygen sensor has a lot of miles on it (more than 100,000) it's probably worn out.
The oxygen sensor screws into the front exhaust manifold. Look straight down and you'll see it. It looks like a spark plug with a thin wire trailing from it.
The oxygen sensor is located in the exhaust manifold before the catalytic convertor. If you look down between the radiator and the exhaust manifold a few inches before the exhaust pipe connects to the exhaust manifold you will see the Oxygen sensor. The sensor will have 2 wires coming from it and it kinda looks like a sparkplug stuck into the exhaust manifold. There is 2 nuts that hold the oxygen sensor into the exhaust manifold.
It has two. They must be replaced, not cleaned.
the rear oxygen sensor is located under the car just in front of the catalitic converter it looks like a wire hooked onto a spark plug in the middle of the exhaust pipe
The oxygen sensor that typically fails is attached to the exhaust manifold, just above the headpipe. It looks a little like a sparkplug, and has an electrical connection. The OTHER oxygen sensor is behind the catalytic converter.
