Cost of a mechanic finding and fixing a EVAP leak
2 weeks ago, I got a check engine light. I took my car to Advance and the clerk hooked up a scan tool to my car and error code P0456 come up. The clerk suggested I get a new gas cap and I did. A week later (Today) the check engine light came back on. Took my car back to Advance and the same error code came up but the gas cap wasn’t the problem. It has to be a leak somewhere in the EVAP system. I did some research and I felt that solving the problem myself might be out of my league. I might have to take my car to a mechanic. Have anyone took their car to a mechanic to fix an EVAP leak and how much did it cost?
