Just bought my 06 Pontiac GP GT the check engine light came on on the way home with it so i took it to my mechanic and ran the diagnostics and it threw a po033 code "Bypass valve stuck open" so I brought it back to the dealer so they can fix it. Did a little research and saw that it could be the solenoid. Just wandering if anyone has ever ran across this problem and if so what is the average cost of repairs.
