Does anyone know exactly what's wrong when the code reads P2A00 and P1172? I know it says Air Fuel Ratio (A/F) bank 1, sensor 1 Circuit Out of Range High.

I researched this and it appears that the 350z and TSXs have this issue, wondering if the s2000s have any with this also, if so is it the upstream O2 sensor or downstream O2 sensor or if it even is that issue at all, thanks in advance!

 

downstream should be bank 1 sensor 2

 

Cool thanks! I hope this is the issue...just by replacing it

think you might mean P0172?

Guessing you have a flashpro?

 

marc88, actually no, mine is all stock, no mods. tkeyy, yea the code is P1172 and P2A00, could it also be the MAF sensor?

 

Has your car been to the dealer for any service in the past few months?

 

I recently brought my 2008 in for the CEL P1172 error. They replaced the following part (36531-PZX-013):

i never actually brought my car in to the dealership for any service, I try to do the basic maint. myself but the car only got 32,XXX.

hey DC, thanks, I'll look into that. do you still have that issue now?

 

Did you look at the link I posted?
