Kia Troubleshooting Questions? Ask a Mechanic
Hello. I see you've replaced quite a few things. Has the system been smoke tested to check for leaks?
Ok, sounds like its probably a wiring issue. Let me find some diagrams and check it out. I'll get back to you as soon as I can
Ok, check to see if you have power at pin 2 of the canister close valve connector, its an orange wire. Then check if you have ground on pin 1 of the same connector (key off for this one). If you have ground at the white wire with the key off, you're looking at a short to ground between there and the ECM, which would cause the valve to stay open all the time, until the key is off because the power is controlled with the main relay, so that would explain why you aren't finding any leaks. Let me know what you find and we can dig a little deeper if you have to trace that wire to the em
I would think that it wound not cause a leak but it still should be replaced, it could contaminate the valves and maybe jam them open.
Ok. Have you checked the fuel pump gasket? If that is good, and all of the lines are good the only other option is to replace the canister since it is broken apart. Aside from that there is nothing else that could be causing it to throw a code for large leak, except for a failed ECM
Unfortunately there aren't any software updates or TSB's for that issue
I mean really at this point just put a canister in it, everything else has been done so if you can't find any leaks thats probably gonna be it.
Its an overfill limiter, unless its cracked it shouldn't affect the system sealing
No it shouldn't
