Hi.
i would ask the garage for the actual fault code, as the diagnostic on almost all cars will tell you which sensor is gone.
when you get the code, write again with the code, and car make and model, and i should be able to tell you which sensor is gone.

there is no real way to bench test these sensors.

Try to retrieve the actual code by using a code scanner. Usually when the code definition is "Bank 1 Sensor 1" --- this is the upstream oxygen sensor closest to the engine bank with cylinder no. 1 on it. If the engine is a "V-6" , you might get "bank 2" for the side of the engine opposite cylinder no. 1.

"Sensor 2" on the other hand, indicates the downstream oxygen sensor; or the one after the catalytic converter.

I hope this helped,

Have a great day !!!

I took my car to jiffy lube, 2004 dogde stratus, 2.4 l , to get my 02 sensor replaced. Now my ingine light is on the code was PO420. I wonder now if he kept my new sensor and never replaced it with the new...


Alot of times an in effective catalyst code and an O2 sensor code can be set from an engine vacuum leak. Engine sensors can not see a vacuum leak, but they can tell when an engine is running lean and associate it with the emission system. My suggestion is to have your mechanic look for a bad vacuum hose or elbow.

My 2001 passport check engine light was diagnoised by a local parts store as oxyge sensor, now i find out that there's more than one (1) How do i know which one to replace or do i just replace them all or...


No I can not give you the code number because I did not scan it for you. The Diagnostic Trouble Code will show ( example 02 Sensor Bank 1 sensor 2 ) for the sensor at fault, or something simaller for one of the other 02 sensors. Fore ( example 02 Sensor Bank 2 Sensor 2 ).The parts store that did the scan for you should have given you the particular fault code as well as its location. If you replace one 02 sensor, you should replace all of them. Good Luck and have a good XMASS.

Escort has engine light on, diagnostics say 02 sensor is out, both were replaced, same code for 02 sensor bad shows up, replaced again, same code shows up


MOST OF THE TIME AN 02 CODE DOES NOT MEAN REPLACE 02 SENSOR..SOME AUTO PARTS STORES WILL SCAN YOUR CAR..TELL YOU CODE 02 SO PEOPLE AUTOMATICALLY REPLACE SENSORS...IF YOU CLEAR THE CODES DOES THE CHECK ENGINE LIGHT COME BACK ON RIGHT AWAY OR DOES IT TAKE A LITTLE TIME... IF IT TAKES A LITTLE TIME THEN YOU HAVE SOME PROBLEMS THAT ARE CAUSING THE EMMISSIONS TO BE OUT OF RANGE.. IF THE LIGHT COMES BACK ON RIGHT AWAY YOU HAVE A PROBLEM IN WIRING HARNESS BETWEEN THE SENSOR AND ECM....MAIN COMPUTER.....OR SECONDLY POSSIBLE PROB IN THE MAIN COMPUTER...GET SOME OF THOSE ANSWERS AND FIND THE EXACT CODE THAT RETURNS THEN GET BACK WITH ME FOR MORE HELP

Engine light wont go off.


The catalitic converter is a mechanical device , it simply converts harmful emissions into water/vapour. The 02 sensor if faulty would put the engine management light on. If the 02 sensor has been faulty for sometime it could tell the ECU to supply the wrong amount of fuel to the engine which in turn would eventually damage the catalitic convertor. So you may have to change both in the end, but first I would check out the 02 sensor and replace if required.

Check engine light on car jerks


If you have the 2.7L 6 cylinder, it's located in front of engine,or on the right side of the front of the engine just under the top radiator hose. There is a 13mm bolt that has a wiring support tab attatched to the top of it. Remove tab and bolt, pull on sensor with your fingers, should come right out.

O2 Sensor


not very, but I own an 04 envoy, same engine light troubles, figured it was the o2 sensor, so I took it to my mechanic to have him tell me which sensor, so I could replace it.  Turns out the sensors are fine, but the secondary air pump is malfunctioning and needs to be replaced.  This is apparently a very common problem with this car, and I would suggest having a diagnostic ran before replacing anything, and besides, if it was an 02 sensor, there are 3 or 4 of them on the envoy and you need to know which one is failing anyway, and only a diagnostic can tell you that.
