I had various warning lights come on about 6 months ago. (Check engine, VSC blinking, Traction control) I read that the first thing to try and remedy was to replace the gas cap since that is fairly inexpensive. I did so and the warning lights went away until last week. They are back. I purchased a car scanner to see what codes it would show and those 5 in the subject line are showing. Should I just take it to a shop?

This is an easy EVAP leak and pump problem,

P043e Code: Evaporative Emission System Leak Detection
P043F Evap Leak Detection Reference Orifice High
P2401 EVAP control circuit has had a fault with the leak detection pump
P2419 Evap System Switching Valve Control Circuit Low.

I would raise the car up and follow the EVAP system lines to see if one is off or has a hole in it, if not I would replace the charcoal canister (leak detection pump) and then clear the codes, please check out the images below to help you fix the problem. Please let me know.
