Po325, What Does It Mean?

[PK_3]

Hello,

I just got through replacing the MAF (PO170 I think) and now after a few months this PO325.

The thing about the CEL is it comes and goes

You may have a bad knock sensor or wiring. The wiring is under the intake manifold and could be shorting or breaking. The other possibility is bad gas causing poor running and the knock sensor to detect spark or timing knock. here is info on the knock sensor and wiring:

Ok, Thanks,

My OBDII alluded to that (knox sensor) At 80k though that seemed premature and a real pain. Makes a little more sense to check for faulty wiring to before I go hole hog.
