Knock Sensor

[Bush Bandit]

First posted in the troubleshooting forum but didn't get a response so hopefully I will here

 

I have a P0326 code that keeps reappearing on my 2017 Silverado 5.3. I've cleared it twice but it's back again. There's no apparent knock or any irregularity so I'm assuming a bad sensor. I bout a new AC Delco sensor today for $26 and hoping to have time to install it this weekend.

 

Does anyone know where this sensor is located? Code says it's on bank 1

 

Is this a common issue?
