Never know enough about OBD2 system, But i keep getting evap error codes large small leaks, i went through the system found bad purge sol. replaced it then replaced rear vent solenoid and checked the lines, replaced gas cap twice, and then i thought i would play around with trying to fool the system and i disconnected rear vent sol. connector. to see if leak would go away or not come back and found that while disconnected i got sol code right away, ok understandable but leak code for evap system never came back. So disabling vent sol will that stop OBD2 from coming on or is this program depended on not coming up with evap leak detection if vent sol is diconnected or did i just prove that rear vent solenoid is doing the leaking and is bad after 2 months of being new. ?????? Someone has been through system before and maybe tank was dropped for fuel pump because i see all new hose clamps. So if what i did proves nothing then i guess next step is smoke test and proably come to find out O ring was screwed up when fuel pump was done. All the hoses are in great shape as well.
During the time after replacing purge and vent sol. system did self pass for awhile and then came back again. Even cleaned up gas tank area where gas cap seal sits.
Any thoughts here.
