Throttle Actuator Control

For those who have an 05 Scion TC, beware.

I have a 05 Scion TC which i got in the Summer of 04. I have just passed the 36000 basic warranty and now my car has a problem which is only covered by the basic warranty.

The Throttle Actuator Control (TAC) is messed up. I found that out when the engine light went on. I had an OBDII meter plugged in and it says P2102 TAC low engine circuit. What happens is that when it malfunctions, the car goes into the Limp-In Mode. The car will not go pass 3000 RPM in neutral and can only move in the 1st gear. I bought the car into the dealership and they told me that it will cost about $1400 to repair. Why it happens I have no idea because the dealers haven't told me much. This is an electrical problem so the powertrain warranty does not cover. So for those who have not yet passed the 36000 basic warranty, get it checked on by the servicing department.

i'll look into it.

screw $1400.... have you done any modifications to the vehicle? anything out of the ordinary happen recently?

any other details that you have will help.. if not, i'll find out what uhm.. i can find.

there was nothing done to the car. no aftermarket parts. everything is still the same since i bought the car.

i bought it to my mechanic and they said they can get the part for about $700-$800. thats still a lot but better than paying 1400 for it!

nothing out of the ordinary happened. just driving it like usual. this just happened out of nowhere. i picked up the car this morning from the dealer and it won't even start up anymore. it would start and die right after. i had to get it towed to my mechanic.

Give me a few days and I will have this researcched for you. Maybe a simple part swap or something more extensive. I have to go thru my manuals.
