Performanceproducts.com offers a new one for $133.00. If you live in a state that doesn't have smog tests, then remove the instrument panel and pull the light bulb from the O2 sensor idiot light. Happy motoring.

What is problem repalced egr o2 sensors and check engine light still on?
Have the system checked for codes. That will lead you to the problem.
Where is oxygen O 2 senor located in 1989 300E Mercedes Benz?
O2 sensors are located in the exhaust system.
Would light come on if problem with catalytic converter?
If it has a downstream O2 sensor the check engine light will come on but if it does not the light may not come out. In most instances it will set the check engine light.
Hi i heard that if your check engine light is on you cant pass the e check even if the o2 censor is working properly how do you fix this problem?
go have your engine scanned to see what the problem is the o2 sensor is not the only part in the emissions system
How do you tell if a o2 sensor is bad?
Your check engine light will come on, and when you go to the auto parts store and have them run the fault codes and it says O2 sensors, you will know for sure that is the problem.
What does it mean when my check engine light reading says O2 1 stuck in lean?
The engine computer is not seeing the O2 sensor move off of lean like it should. The O2 could be bad, The wiring could have a problem, or there could be a running problem that is making the O2 read incorrectly. With out a scan tool and a service manual this is very hard to diagnose.
What causes the check engine light to come on in a 1996 Toyota Paseo?
It could be anything, but the most common problem is the O2 sensor.
How exactly do you reset the O2 warning light on a 1992 Isuzu Trooper I know you need to do something behind the speedo but what and how?
On my 93 Trooper there is a "switch" behind the instrument cluster that resets the O2 replacement reminder light. I have read that it reminds you every 90,000 km. I say "switch" because it is actually a screw that you remove from one hole and put in an adjacent hole. Both screw holes are labeled - "KSW" on my cluster. This is a separate dash light than the check engine light. You can not do this without removing the cluster. It might not be an O2 warning light. It comes on when the computer detects a problem with the emissions controls. It may be a bad O2 sensor or it may be many other things. Don't assume it means the O2 sensor is bad. You may be able to reset it by removing the + battery cable for a few minutes. If it comes back on after resetting it, then the problem was not a bad O2 sensor.
Why is your check engine light still on after the problem has been repaired?
If the light is still on after the repair then you did no repair the problem you just think you did. I assume you reset the light. If not reset it and see if it comes back on. If so, you have another problem. If you retrieved the code and it pointed to, as an example, a problem with the O2 sensor, that only means the O2 sensor is being effected, and not necessarily that the sensor is bad. Any code only tells you what part is being effected not necessarily the defective part. That is where skill, knowledge, training, and diagnosis comes into play.
What is the meaning of the check engine light?
The most common problem on "Engine light" on the dash board means it's time to change your O2 sensor. the "check engine" light is an indication that there is a problem with the computer controlled and or monitored emissions systems. oxygen sensors are just one thing that could be wrong when the light goes on. a tester is connected which tells the technician where the problem is.
You have a volkwagon jetta vr6 2000 2.8 manual trans my check engine light came on you had the cat changed and both o2 sensors 250 miles later my light came on again 0420 CODE?
well I read about this happening somewhere else I cant really recal it but from what I remember the o2 sensors where changed and then there is a problem in the wiring with o2 sensors
1998 s-10 which o2 sensor usually goes bad first?
Your check engine light codes will tell you which one is bad if there is a problem with them.
