I have a 06' Maxima....and my check engine light came on. I was told it's the oxygen sensor. is that easy to replace? How many are on a 06 model?? I'm new owner had the car 5 months.

 

4

2 pre cat and 2 post cat

 

easy depends on which one

 

Same light with my own question. I hope I am not jacking your thread.

I want to replace my cats with racingline HFPC. Which oxygen sensor should I change? I was hoping to change only one or maybe 2?

Which one or ones should I change? And what are the part number(s)?

 

What the easiest way to find out which one it is? I went to a auto advance place and he told me that. I don't wanna pay someone alot to tell me which one it is.

 

It's cool PetitFrereMaxima I don't mind.

 

What code are you pulling? I'm assuming its the ones after the precats.

 

Well after taking it back to be diagnosed it turned out to be the catalytic converter No telling how much this will cost me.

 

It happens to a lot of people

one option is racingline high flow cats

 

I just got to figure out if it's the rear or front one. Ugh I have such bad luck with cars knowing my luck it's the most expensive one. :/

 

Most likely the rear

P0420 is the rear (firewall)

P0430 is the front
