Thread: O2 sensor

I had my cat cut off on my 2000 gtp and was wondering if the secondary o2 sensor not being hooked up will cause fuel trim problems or is that just the front one. right now Im getting a ses. I have an zzp o2 sim going in anyways but I was just wondering.

ses is from no rear O2.

since your car is a 2000 you shouldn't have any issues with the fuel trims being off from the lack of rear O2.

ok cool ty,
