Where is the oxygen sensor?

Most are located on or near the exhaust manifold.

An Oxygen Sensor (O 2 S) or heated Oxygen Sensor (HO 2 S) is used on all engines. The sensor is mounted in the right side exhaust manifold on some V8 engines, while other V8 engines use a sensor in both right and left manifolds.

Heated oxygen sensors are located in the exhaust pipes below the exhaust manifolds. The sensors react with the oxygen in the exhaust gasses and generates a voltage based on this reaction. A low voltage indicates too much oxygen or a lean condition. Where as a high voltage indicates not enough oxygen or a rich condition.

Disconnect the Oxygen Sensor (O 2 S). Measure resistance between PWR and GND (heater) terminals of the sensor. If the reading is about 6 ohms at 68°F (20°C). the sensor's heater element is okay.

Hope this helps (remember to rating this free answer).

If you're getting a code for a heated oxygen sensor circuit problem, replace the sensor. I don't think I've ever seen a fuse be the problem. Bank 1 is located at the back of the engine compartment, close to the firewall. Sensor 2 is the sensor after the catalytic converter.

Hello your oxygen sensor is in your engine exhaust manifold

There are two oxygen sensors: one is upstream of the catalytic converter and one downstream of the catalytic converter. The oxygen sensor, or O2 sensor is usually located near the catalytic converter.Oxygen sensor downstream of the catalytic converter in the exhaust system on the back of the engine. ------- Thanks.Helpmech

It is screwed into the exhaust pipe,closer to the converter,than the engine. Will be at least two. One maybe screwed into the converter. Need to know which one,your shop thought was bad.

O2 Sensor Heater Failure Oxygen sensor heater element malfunction solution replace the oxygen most likely the one located in the cat. converter make sure the replacement is original equipment(oe)

There is only 4 sensors on a 2000 dodge intrepid and the bank 2 sensor 2 is the sensor located on the right (passenger) side and the one located after the catalytic converter (the one close to the firewall).

The only thing that comes out of the exhaust with a wire coming from it, is the oxygen senser. It is right behind the manafold.

The O2 is located Under hood, center, rear engine area, above exhaust pipe flange, mounted in exhaust manifold
