I have a code p2a00 I need help with diagnosing what’s causing this code is it the A/F sensor itself or something else throwing it off?, when I was looking at my live data my o2 sensor after the catalytic stays at around 0.8 volts and but does not fluctuate from 0.1-0.8 volts and at idle it stays at 0.3 volts, I checked for vacuum leaks and I didn’t find any, could it be my fuel injectors, 02 sensor, A/F sensor, or my fuel pump?? Help please I don’t want to keep smelling my exhaust and seen it all black at the tailpipe and I’m getting bad gas mileage
Clarification: Mileage? Also, which engine and transmission?
