EGR h32
I keep getting h32 while hwy driving. Any idea how the computer knows something is not right with the egr?
my guess is it can monitor the o2 and it would read rich while sending fuel less fuel that would make it actually lean or something like that. I don’t know of any sensor that can monitor although I’ve read there is a channel for inputs into the aldl that you can use for wide band
I recently replaced the valve that had the diaphragm broken and didn’t solve the problem.
that’s before I begin testing the solenoid valve and vacuum lines
car - 91 tpi
thank you
