Although I am located in Toronto, Canada, it would appear that I have a similar problem to other queries. On May 22, 2012, 104,000 km service performed (actual mileage 103,206)by an independent garage. Engine light on June 5th; computer advised problem due to code EVAP. Gas cap tightened, system reset; light off. Thereafter, I have returned 4 times (gas cap seal reversed, rust removed from gas tank intake,and finally, a new gas cap was purchased). Invariably, the engine light would come on again 2 to 3 days after refueling. However, the last time the light came on was 2 days after the system had been reset. I am now being advised to go to a Toyota dealership and that I may be facing a bill of $3 - $400.00. Was also advised to simply ignore the engine light being on; but of course this may eventually mask another problem. Before consulting a Toyota dealership, I would appreciate any and all advise inasmuch as I was once advised by a dealership that the clutch was leaking oil and that the repair was urgent. A second opinion was sought; no problem found and I drove the car for another three years without any oil leaking from the clutch.
'Check engine' light back on despite new gas cap. on 2004 Toyota Echo

As advised by another correspondent, I finally went to a Toyota dealership about the problem, insisting that first and foremost, all the hoses be checked. Sure enough, "the vacuum hose from the air box was loose". It was "re-installed and the codes were cleared. Had this work done on September 24th and to date, the problem has not returned. As a result of the advice received on RepairPal, I was only charged for a half hour of labour - $55.00. A smoke check would have cost approximately $110.00 - $165.00!!!!!! Thank you, thank you!!!!!!!
