Re: Echo code help please
Make sure the gas cap is tight
On the air cleaner, there is a VSV. It has 2 vac lines and an electrical plug. Make sure the wires are attached properly and the vac lines are installed properly.
If both these items are ok, then you probably have a cracked
OVERFILL CHECK VALVE in the top of the fuel tank.
Toyota has a special tool to pressurize the EVAP syatem and find the leak with a soapy/bubble mix. Its on the top of the fuel tank and very had to see.
If it is none of those obvious choices, then you need a toyota scan tool to monitor the evap system and read the inputs to the ECU and try to see what it is seeing as a fault.
Good luck
