Rchalk Posted July 4 Report Share Posted July 4 Today the "Service Engine Soon" light came on, with no noticeable change in performance. A free diagnostic at O'Reilly Auto Parts returned code P046, EVAP System High Purge Flow. The description says "Code P0496 indicates that the Evaporative Emission System had high purge flow for a predetermined period of time" Can anyone tell me what caused this, and of an owner-repair is possible? The local Ford dealer says probably 2-3 hours labor, plus parts. I'd sure like to avoid this bill if it is something simple to repair or replace. Also, how do I reset the code to determine if the problem is recurring or one-time? Thanks for any help anyone can offer. Richard Quote Link to comment Share on other sites More sharing options...
kruzr1 Posted July 4 Report Share Posted July 4 I'm not sure what it would take to repair the DTC, would have to do some research. But if you initially want to clear the codes to see if it returns, the person at O'Reilly should be able to clear the codes also. I know they can at Autozone, unless it's not allowed in your state.
