My turn with the NA. CEL came on at start up when I left work on Friday. Engine was stone cold and started right away. Stopped twice on the way home and the CEL went off. Scanned when I got home and PO335 was stored. Cleared the code and today I replaced CPS with Bosch CPS I picked up a few years back when they were $35. I have 1 spare left but with 2 cars, I just ordered another spare.
