wife has gotten the knock sensor code, we played around with the gas cap and it fell card it for a few hours.

The light came back, now this past weeekend we reset the light on a road trip, and it came back.

are there any tips on replacing it? Or any tips you guys can give me.

This is is the only code she is getting
p0333 and one time she got 2 codes it was p0333 and p0333 p

Thanks
