Basically you unplug it and then unscrew it from the exhaust pipe.
It has threads like a pipe.

I have 2 codes showing on my 2004 chrysler sebring.? P2096 AND p0137. what do they mean and how do I know what parts to get to fix the problem.


P0137 O2 Sensor Bank 1, Sensor 2 Voltage Low
P2096 Down Stream Fuel System Bank 1, Sensor 2 Lean

There are 3 possible engines in your vehicle, a 2.4L 4-cyl, a 2.7L V-6, and a 3.0L V-6. If your car has a 4-cyl then there is only one downstream O2 sensor. This is where you need to start the diagnosis for code P0137.
While it would be nice to assume that the sensor is faulty, the sensor wiring between sensor and PCM could be the problem as well.
That said, you are looking for a DOWNSTREAM OXYGEN SENSOR. I strongly advise that the replacement be OEM compatable. Avoid Universal Replacement types that use **** connectors to make them work.
Good Luck!

Engine Mechanical problem 2004 Kia Sedona 6 cyl Front Wheel Drive Automatic 100K miles the mpv has a 2.5L, Problem: 1) when press a little hard at the pedal to make the car move, the engine shake...


Nothing to do with valve control but o2 sensor should be replaced and also sounds like the engine is misfiring when gas is applied, this may be caused by a bad coil or sparkplug.when was your last tune up?, i would replace sensor and also make sure there are no other codes , even check for history codes.

I HAVE TO REPLACE A 02sensor on a 2001 taurus V6 30 the code say bank2 senor2 where is it located


Bank is referring to a collection of cylinders. I.E the curb side cylinders. Sensor 2 mean cylinder 2 in bank 2. It is not a O2 sensor. The computer is noticing a fault in a middle cylinder...check spark plugs for abnormal or premature damage

Engine light was on and engine idles rough.


these O2 sensors are cat convertor check sensors. id be checking cat convertors and hopefully you should try replacing if not all ready is the front bank 2, O2 sensor
if you have scanner can you see fuel trims in data display to confirm high fuel trim only on bank 2 either +-5 or more indicates problem and if bank 2 sensor 2 has fixed high 700mv reading cat no good(warm idling)

Cavalier blowing out black smoke car idles fairly well considerin


Black smoke is usually unburned fuel. P0171 reads bank 1 system too lean. There isn't one answer. You need to dig further and inspect your cars fuel system, from the pump to the injectors. Because of the mileage you may want to start off with a compression test just to see where you stand with the motor. write back if you have any other questions.

AUTO ZONE COMPUTER SAID MY 02 SENSOR IN BAD.


Bank #2 referes to the side of the eng in which cyl. #2 is snsr #1 referes to the sensor before the cat. conv. and the code is for a slow response so, basically a lazy O2 snsr. So if you can locate cyl. #2 and follow the exaust manifold on that side of eng. the very first O2 snsr you see is the one in need of diag./repair

WHICH O2 SENSOR HAS THE HEATER CIRCUIT IN IT BEFORE OR AFTER THE CATALYST


Hi.
The Oxigen sensor are in diferent kind.
1 -- With a single wire. " is only oxigen sensor"
2 -- With 2 wires " is only oxigen sensor"
3 -- With 3 wires " Is oxigen and heater sensor"
4 -- With 4 wires " is oxigen sensor and heater sensor.
5 -- with 6 wires " is oxigen, heater A/F sensor" normally Nissan)

OK........Your question.
Depend of the year of your car.
But all the car they are Bank 1 or single bank. Engine in line
4 cyl . or 6 cyl. And are identified sensor 1 bank 1 and sensor 2 bank 1. S11 or S21.
But all the Engines in V are bank 1 and bank 2.
Sensor 1 bank 1, sensor 2 bank 1, S11 or S21.
Sensor 1 bank 2, sensor 2 bank 2, S12 or S22.
Sensor one is alway before catalystic.
Sensor two is alway after catalystic.

If you have problen with the oxigen sensor you need to put a scanner to see the number of code, The number of code will give the especific sensor that you need to replace.
The code can be heater or oxigen. and can be refer to a the same sensor.

I hope this information work for youu.
Thank you for use fixya.
