3rd gen evap canister codes

Hello, i have a 3rd gen 2016 taco with 108k miles and recently ive been getting the codes:
P2402
P2401
P2419
P043f
P043e

it keeps coming up as the evap canister. At first i changed the pump and after 3 days the lights come back on (check engine and trac off). I noticed that the trac off light turns off if i hit 31mph+ but always comes back on after you slow down.

i have put on the whole charcoal evap canister from a junker and still get the same problem so i took it to the dealer and they scanned it and told me it was the evap canister (i already knew this since i scanned it at home and changed the part) so i had to buy a new one this thursday and installed it but today sunday the light comes back on.

its a frustrating process after spending time and money and the problem doesnt get resolved but i have yet to take down the tank and inspect the fuel lines for leaks my self even though the dealer said they “checked the truck for leaks” and cant find anything. Theres something wrong with the truck and the evap canister is not it.

has anyone encountered this problem and had success in fixing it? Thanks

 

Stop overfilling gas tank. Mist of the times I've ran into evap issues its either spiders and webs in the canister and or lines. You can get a smoke tester at HFT and check for leaks. I would go over everything blow it out and re install.

 

Dirtridercrf250, i dont over fill gas tanks. I have not filled up on gas since thursday since i installed the new canister.

 

Lines to canister clean and free ?

 

Yes, i cleaned them and are not hung up or bent. I have a suspicion that this might be a rat problem biting the lines but i havent checked. I’ll probably do it today or tomorrow.

 

GOOD LUCK OP. let me know what you find.

 

The best way to find the leak, a smoke machine is needed. Sometimes mice eat the plastic lines on top of the tank.

 

Yeah i was going to drop the tank to visually inspect it

 

Just got back from deployment and im ready to “try” and fix it. Can i stick a smoke canister line down the gas fill cap? A mechanic told me i would have no problem but i jist dont want my truck to catch on fire. I know i have to do it as close to an empty tank as possible.

has anyone had this problem and resolved it?

 

same codes and problems here with my 16. Did you ever figure it out?
