Have an '02 Tacoma. Recently the CEL came on and the dealer retrieved the following codes
P0440,P0441 and p0446.

The dealer checked the cap and said the cap was fine.

The mechanic at the dealer said it was probably the Evap (I'm guessing the EVAP is the carbon canister?) and it would cost about $400 to change.

Is the Evap the small tank ABOVE the fuel tank? It looks easy to change, IS IT?
Do you guys think its the EVAP? What could it be?

Is there a way to reset the check engine light?

It could be the charcoal cansiter, a short in the control system, or a simple vac leak.

Check the vac hoses on the valves that control the system, and check the wires that connect to them. It is all located under the hood.

The FSM can be found here:
