Evap system code, could be just a bad gas cap, or a line has come loose from the evap system.

Evap codes. It ok to drive. Could be 348 different things.

What vehicle/year?

[BlackHogDown]

I don't remember the exact number but looks really close to the code i had on my 14 chevy. Drove with it for a while before changing the evap solenoid. Most often its a loose gas cap. On chevy of that year at least.

It's a 2002 Camry. Was told it could be carbon, EGR system? "Exhaust gas recirculation"

Google it

2002, most likely a leak somewhere. Could get lucky and just be a gas cap but will probably need a mechanic to smoke it to locate the leak. Shouldn’t be a big fix but you could spend a lot of time trying to locate it piece by piece connection by connection. Love me some epa.

My wife’s 4Runner has done that. Change the gas cap first, it’s a cheap fix to check first

Will not be the EGR.
