P0140 and P0442 together
Hi.
I have these two codes together (P0140 and P0442). I replaced the O2 sensor (B1S2). I am working on the small EVAP leak (P0442).
I noticed that in the diagnostic steps for P0140 that the DTC won't run if P0442 is set. I was just wondering why. Could a P0442 small EVAP leak have an effect on the fuel/trim and thus throw B1S2's readings out of range?
