P0325 is related to the knock sensor and or the wiring to it.
Check the wire it could be loose , did you have the starter changed? The knock sensor lives just above it, beside the oil pressure switch.

I had to replace my Oil Pressure switch a while back, and found it much easier to just drop the starter and replace the switch from underneath. You may want to consider dropping the starter as well, being the knock sensor is in the same area as the Oil Pressure switch.
(the starter comes out pretty easy)
