Question

How can I repair this or care this up

Answer 1

HI there

This code points to a leak in the evap emissions system. This could be as simple as a bad gas cap or something more serious like a bad vent control valve. I would start with a new gas cap and clear the codes. If the code comes back, then the next step should be a smoke test. This will show the location of the leak and then you can repair it without throwing a bunch of money at the vehicle.
