Question about 2002 GMC Sierra 1500HD
Their are 2 knock sensors located under the intake manifold you can't see them without removing the intake, they go bad quite often and I have replaced lots of them if attempting this repair on your own you should buy a book, one sensor will be bad, usually the rear due to water intrusion but replace both while your in there
