How much should I expect to pay to replace the EVAP?

what parts are you replacing?

Hello, What Stevieray1 is getting at is that these codes do not tell a technician, or anyone else, what to change, they only say what fault has occurred. It is up to the person diagnosing the vehicle to find out why those codes have popped up. There are several issues that can cause the EVAP system to fail, from a wire being worn to exposure, to a bad purge valve or pressure sensor. You will want to use the link here, and select general diagnostics. Once the issue is proven, the servicing technician can recommend repair, and the shop writer will deliver a quote. https://repairpal.com/estimator/chevrolet/equinox
