While driving home the other night I got a check engine light. The code that appeared was P04F0. Anyone seen this code before? From the TSB I found it possibly a PCV valve. I cleared the code and it hasn't come back and I put another 75 miles on it since it was cleared.

 












Generally a "performance" code such as P04F0 "EVAP System High Pressure Purge Line Performance has been detected.", generally means the high pressure purge line has failed.
