Hey guys! Added another GMT360 to the family, a 2008 TrailBlazer LT. Its been well kept up and maintained. There is one issue I'm having, the CEL came on for a knock sensor. The code is P0325 Knock Sensor 1 Circuit according to Torque.
I've got paperwork from the previous owner showing one of the knock sensors was replaced by the dealership a few months ago. It doesn't say which location it was, and I can't seem to pinpoint which sensor it is. I know there is one on the Left side of the engine block by the A/C compressor, and the other somewhere behind the block by the starter. Anyone dealt with replacing this one before?
