Hi everybody!

I got engine check light along with two more lights on, and the guy at the oil change station said that this is something with the Fuel tank Ventilation system... (please see the picture)

Anybody had the same issue? And what parts was needed to get fixed or replaced?

Thank you for your replies in advance!

I had the issue, the cause was a short in due to Toyota's crappy design of the harness that goes from the rear body to the bottom of the tailgate. Flexing of the harness due to opening / closing the tail gate caused chafing and shorting out.

You've got a check engine light, a vehicle speed control light, and a traction control light. How in hell does the oil change guy deduce that the issue is caused by the tank ventilation system??

Does the truck start, stop, and drive OK?

Are all lights working?

If you find nothing obvious, I'd run it to a dealer or to a shop specializing in Toyota's.

i had these lights on a few weeks ago after a few carwashes that include underbody wash after the winter. i just replaced the gas cap ($20). Fixed.
