Are you running the stock drive by wire throttle body, or is it upgraded to a cable throttle? If it's still DBW, going into limp mode is indicative of a failure of one of the two APP (accelerator pedal position) sensor circuits.

Yes, still DBW. And it does seem to be in limp mode.

Guys, he knows what he's doing

If it started when he was almost out of gas then there was probably gunk floating on top of the fuel which has now clogged the fuel filter, fuel pump or an injector(s).

Although with it being only one cylinder I would probably rotate the injectors around and see if the misfire moves, before I pull the fuel pump/filter, but I also have an interior in the way.

Good to see it on the track!!!!!!!!!

Just to eliminate it as a possibility, and so we don't have to do it later, we are taking the fuel injectors and pump to RC Engineering this week to have them tested and cleaned. One less thing.

It is a very rare day when I don't love my job... But some days it just gets better. Hearing of our small stumble, we have been invited to bring the Yaris to the Toyota tech center for a once over and any help needed to get it in tip top shape for the upcoming race.

Having access to all of the proper diagnostic tools, and the guys who can fix these cars in their sleep. Priceless.

Are you referring to Toyota USA head office (TMC) in Torrance?

P.S. I used to work for Toyota Canada technical training, so I'm not a noob to diagnosing a toyota either. So hopefully it just a wiring problem messing with signal, or just the fact that you ran the tank dry.

Toyota has a lot of buildings stretched over a few square miles of Torrance.
