Hello! Welcome to justanswer!


That code is for a bad EVAP solenoid. See the diagnostic procedure below. Also in that PDF is the replacement procedure for the solenoid which is most likely what you will need to do.

would a loose gas cap trigger this?
Expert:  Anthony replied 7 years ago.
No this code means that the purge valve's electrical circut is damaged or the valve itself is. Definately not a bad fuel cap.
