Q: System Gross Leak Evaporative Emission p0455

asked by on

hi if i get a oil change and a tune up will this fix the problem

My car has 183000 miles.
My car has an automatic transmission.

The code P0455 will not be fixed by having an oil change and tune up. The evaporative leak may just have been caused by a loose or leaking gas cap. The system will need to be tested by leak testing with smoke to see where the leak in the system is. You may find a leaking purge valve.
