Yaris Check Engine Light Flashing

[zwalker]

Today I was driving my 2007 Yaris home from work on the highway and while I was going uphill the automatic transmission geared down like it always does when Im going up large hills but this time the check engine light started flashing for a few seconds. I have never seen this before. The check engine light did not stay on.

Anybody know what this could be? In my experience this usually mean and engine misfire but if so what would cause this? Should I take it into the dealership? I am literally 1000kms away from the end of my 60,000km comp warranty.

Note: I have only been averaging 31-35mpg at 100km.h all highway

Take the car to the dealer,If the light was flashing it should have left a code.
