My 2018 CRV ex keeps throwing p219c,e and f. Gone to two mechanics and neither could pinpoint the culprit. Finally discovered when I clear codes I can travel for hours in stop and go and highway and no ck engine. But as soon as I stop, turn off and restart code comes up. Any ideas? Want to avoid dealer!!
