Have the code erased with a code reader.
Gas cap code p0449 ??? This is not a gas cap code !
DTC P0449: Evaporative Emission (EVAP) Vent Solenoid Control Circuit.. your best bet , take it to a qualified chevy repair shop .
Wells EVAP Training with Sgt Tech P0440 P0441 P0442 etc
Had the same problem. Ck eng light came on. Code read p0449.. It said something about rear solenoid located behind gas intake. Took it to an auto shop ready to give up a few hundreds, they laughed, erased the code and told me to change my gas cap. I ordered one from Amazon. Light came back. Finally Put on. Ck light stayed on and A few days later finally disappeared.
