CODE SAYS IT'S A KNOCK SENSOR

2004 GMC Sierra • 127,000 miles

I recharged the k&n filter on my 2004 gmc sierra and the check engine light came on. The code says it's a knock sensor. Is there an easy solution?

Try cleaning the maf sensor because you probably put to much oil on the filter. Have teh code cleared and seeif that takes care of it
