Good morning question for you I’ve got an O2 Chevy Silverado Z 71 she has 315,609 miles on her the only maintenance they’ve really done is recently replaced the hub bearings for the front. My question to you is the only code the truck throws is a knock sensor, but it runs perfect with that many milesone would you replace the Knox sensor even though she’s perfect and question two what kind of maintenance tips do you have on a truck with that kind of mileage?
Yes I would change the knock sensor cuz that has to do with all the vehicle runs and if it doesn't run correctly it could damage the inside of the engine even though you wouldn't hear it. Now you'd hear it later when damage was done. Otherwise, just keep doing what you're doing. I'm assuming you're changing the oil regularly and change the coolant once every three or four years
