Hello Scotty..I have a 2012 Kia Soul and check engine light comes on after I fill gas tank..Diagnostic code is P026..dealership said it was top 02 sensor so had it changed..one tank of gas later it came back on..when I get to under a fourth of a tank it goes off..any help would be appreciated.

26 is a code for intake solenoid problem , has nothing to do with oxygen sensor, You may be giving me the wrong code number
