P0335

[Trucker2k16]

Hey silly question my new 6.5l optimizer threw a p0335 about a week ago it still ran fine and still does i was doing 30 mph and i heard what sounded like a cold rattle when the light came on. It hasnt came back on since then i have a acdelco cps to put in and get rid of the cheaper one i got the first time could it of been a fluke?

Could even be a poor connection or ground. I'd change the CPS and see if it comes back
