I see this error code on my NA 350z...
My mods are: metallic hi flow cats, Nismo headers and Nismo exhaust.....
I see on the forum that this code comes only with a FI 350Z...
Am i correct?
Which is my problem with my car????
On my workshop manual i can't find the code...

Please help me ....

 

air fuel ratio sensor 2

probably running lean, or rich... not sure which one.

get the car up on a dyno with an AFR sniffer to check, but you probably need a tune or reflash.

 

Ok... thank you so much....
I forget to say that i also have an Utec on my Z.....

 

Time to check air/fuel ratio then... and while you're at it, post up datalogs of your tune in the tuning forum

 

Ok....Thanks again...
