Yea we tried the contrib while the ac was on and it wouldn't and it also listed the AIH code. Oh well.
Active? No. I shoulda cleared em then tried it again but didn't have that much time. It was just a 'let's see what this thing will do' kinda deal.
So if the P0237 is "Signal frequency was greater than 256 Hz. for more than 0.1 seconds" and "203 Hz. 25.3PSI" then I was pushing more than 25lbs of boost? Or could it be a MAP problem?
No, wastegate is plugged in.
Would the EBPV codes be both from it being unplugged?
I'm not too worried about anything, just curious.
