I put in 2 brand new 02 sensors front and rear cause they were both bad and now and week later I have a check engine light code saying the front sensor is bad how could that be its brand new.anyone know?thanks

 

Just cause you get a code doesnt mean they are bad. Sometimes you get exh leaks before the O2s from cracked manifolds or broken manifold bolts that can cause codes

 

It depends on which codes you are getting, but there are diagnostic procedures for all of them can usually help you determine what is causing the code. I had a code for a rear sensor so I went to the auto parts and bought one but when I got under the truck I found the wiring to the sensor melted. It was not secured properly when my transmission was replaced and touched the exhaust. Fortunately, it was not melted all the way though and I on my return trip the code cleared.

 

I know weed is gonna get me for this lol but what brand did you get? It seems a lot of people have codes come up when they use bosch (weed your one of the few that seems to have no problem with them lol)

 

True, never have had a problem with mine. The masses seem to go with other brands. I *think* I paid about $25 each for mine

 

they are not bosh they are idk .

 

Goto the stealership and get the mopar ones!! I had a hell of a time with mine!! My truck would not accept the bosch's!! I had to go to the stealership and get the factory ones. Do urself a favor and throw away the bosch's and get the factory ones!

 

idk as in I don't know?? If you don't know, how do you know they're not Bosch? Am I missing something? Some have luck with Bosch, and some do not. I would agree, best to go to the dealer if you're still having problems.

 

NTK would be the brand. You don't have to go to the dealer. I think Pep Boys or Oreilly's carries them.


IDK....I have no idea


Some people get lucky with Bosch. As for myself, I don't like putting 3 of them in until I get one with a working heater. The cheap Bosch ones are really FAT looking.
