Hi,
I’ve been getting an intermittent p0325 code for knock sensor bank 1. Symptoms are a CEL and rough acceleration/driving at slow speeds when code is active.
Bought the OEM sensor to replace but cannot find any documentation on the 14-18 year Silverado on where exactly it is, and how to swap it.
Two main questions - a) how do I swap the sensor itself?
b) if it is the harness/wiring that plugs into (I read in here that the wiring connects near the vacuum pump which I just had replaced from dealer warranty recently) where exactly is it and how do I test either one of these to know which one is faulty?
