Oxygen censor where is the oxygen censor located

• Bank 1 is referring to the side of the motor with cylinder 1, usually the driver side. And it would be the 3rd sensor back. Its probably not dual exhaust so its just referring to the rear o2 sensor located after the catylitic converter. Hope this helps.

Sounds like you might need a valve job.

this is the oxygen censors location, hope help....

Yes they can surely cause an misfire.

I cannot understand your statement "wich sensor is in bank 2"

If i am not wrong you are asking which sensor is present in bank 2 .

The 4th O2 sensor is located in bank 2

The oxygen sensor is located in the exhaust system, either the exhaust manifold or the exhaust pipe very close to the manifold

O2 and oxygen sensor are the same thing and depending on make model and motor there can be anywhere between 1 and 4 O2 sensors on your car they are located in the exhaust pipe or exhaust manifold before catalytic converter also might be one behind converter
sorry i cant be more specif without knowing what motor and model you have

For 1997 Mercury Grand Marquis 4.6L SFI 8cyl the Oxygen Sensor is located: Under vehicle, passenger side, below seating area, mounted in exhaust pipe in rear of catalytic converter

Application: Number three


Hope helps (remember to rate this).

The location for these types of sensors varies from vehicle to vehicle.

Odds are your manual won't tell you.

Get a Haynes or Chilton manual (free at most libraries) for your make , model and year.

The location, plus changeout info will be in it.

You would use an oxygen censor socket to repair that. You can buy one for pretty cheap or you can rent one from the parts house. You'll want to disconnect the electrical connection to the O2 censor, slip the socket over it (using the appropriate ratchet) and take it off. You can also use a 7/8 inch wrench on most cars if you can get it in there.

The Oxygen sensor is located on top of the catalitic converter which is as viewed from under the van between the firewall and the Moter/tranny. It's got a wire coming off it going into the harness. The shop charged me an hours labor to change it out and probley only took 5 minutes.....
