Im looking a buy at 97 gmc sierra. Knock sensor code shows on my code reader. Is that something to worry about? The truck is in mint condition and seems to run fine. But the code reader is reading a code and it say "knock sensor 1 circuit high input(bank 1 or single sensor). Is this something I should worry about before buying the vehicle, or is it and easy fix.
