Question

how much is it to repair? If other than the fuel cap....

Answer 1

Hi there,

This code is for a leak in the evap system. This can be something simple like a loose gas cap or a bad cap, or something more complicated. Usually the best method for diagnosing this is to have a smoke test done on the evap system, then once the leak is located do the repair yourself to save some money.
