Knock sensor code permanent code showing

[jf87]

I have a 2010 Tahoe that his constantly showing a P325 code. The code is always on even after deleting and before you turn motor on. No other code comes up. Also new wite harness, knock sensor. Has anyone had this issue?

I just fixed a similar issue I had on my knock sensor B2. Turned out the pig tail wire was corroded. New tail and sensor while on there. Same issue traced wire to under the crank and had a cut in the wire try tracking the wire down.

You are already receiving sage advice from the knowledgeable folks on this Forum.

I've seen other posts here where the recommendation is to change the wiring along with the knock sensor.
