Have check engine light. Found code, P 0455, Thru. ignition switch sequence, Thanks everyone. Problem was EVAP system leak, gross. Found rubber tube on canister split. repaired.
Question: Will check engine light reset itself with this code? If not, is there a way to do it without going to dealer?
Thanks in advance

First off welcome to the forum and I'm glad to hear the issue was resolved. The CEL will most likely need to be cleared. Autozone has a scanner, i dont know if it can clear the CEL. The dealer will definitely be able to clear it though.

You can use this method,but will lose your presets on your radio:

To reset your engine codes:
Remove the negative terminal of your battery (10mm wrench).
Turn your ignition key to START and hold it there for about 15 seconds.
Turn your ignition key to OFF and remove it.
Connect the negative terminal of your battery.
Start but do not hit the throttle. Idle for about 10/15 seconds then turn off.
Restart the truck and drive as usual. It will take at least 12 starts and 48 miles to fully retune the computer. Hard Codes leave a shaddow for 40 full cold starts

It will eventually reset itself as long as the fix worked and no leak is detected. I am not sure how many driving cycles it will take. (cold start to normal running temp)

The only other way I know of is to get an OBDII code reader/scanner that can reset codes. This might come in handy anyway since you can use it on any vehicle that is OBDII compliant.

455 should reset on it's own rather quickly after a few cycles (at least mine did)

But if you can't wait, the battery disconnection suggestion above will work.
