Hi
I'm having a weird problem with my oxygen sensor of my S14a sr20det.
Cold or hot engine, it Always has a value of 2.55 even when its unplugged.
Does the value normally need to be between 0 - 1?
What could be the problem?
Car runs perfect on idle, still on base map. (Original injectors and maf)

Re: O² value to high
Check your wiring. Check the O2 input line and see voltage. Dare say its shorted to 12V
Re: O² value to high
Ok thx Matt, will check the input line tomorrow
Does my fuel map look OK or?
It's an s14a sr20det , everything Original, except 3 inch exhaust and Apexi avcr @ 1.05 bar

Looks smooth, but the AFR trace is what you need to really see
Re: O² value to high
tested out de lambda with heating it, looked ok. 0-1v ..
But still wasn't sure, so i order a new one, problem solved lambda is now 0.82-0.83
