O2 Readiness

dakarwu · 03-16-2019, 01:44 PM

i just detune from catless to cats to get ready to pass smog but my system says 100% ready. I couldnt find any evap or o2 sensor readings. Am I doing it correct? would it be under engine diagnostics?

Have you driven the car yet? I had to go for a 50 mile drive after de-tune to get system ready for smog..

I ended up not passing or failing. Cats, o2, and evap not ready. I am going to work on the drive cycle but it might be difficult living in la. Is it possible to finish the drive cycle on a lift?
