Possibly you need a throttle body??will check tomorrow at work to see if I have more info.Does the car run/drive o.k.?
the car drives fine when but when u try give it some gas like your trying to pass someone quickly the rpms jump up about 500 to 1000. ive read on the fourms about this code its throttle accuator motor circuit low and no one had a concrete answer. all i have is a turboback an accessport and hks blowoff valve(trying to get a stock recirculating valve) so if anybody has answer it will help tremondously because i have a good feeling that the dealer is trying to rip me off.
Possibly a TPS sensor? That or the throttle body motor is shot. Sorry, nothing concrete on that one. Is your car a drive by wire car? What year is it?
Replace your throttle body assembly. The motor is faulty. If you get denied warranty coverage for some reason (according to warranty info its covered by the 3yr/50k mile Calif Emissions warranty), I have a ported one from an STi for sale. $200 shipped. The drive by wire throttle body/motors/sensors are all one sealed unit. You cannot order individual parts separately. New this thing goes for $538.66 retail, I can get you a new one for around $460.
I figured wjm would chime in here eventually He seems to be the man when it comes to diagnosing cels!
