Hi,

This is my first post so hello to everyone here.

I have a 2006 G6 with about 53,000 miles on it.

The past couple days I've had the infamous error message come up saying "Engine Reduced Power", then the engine light comes one, and also the TC light. This is usually happening in the morning when it's cold, then later in the afternoon, the engine light goes out and it runs fine. A couple days later I will get the error again and the car will barely run. I have to shut it off for a few minutes then it seems to run ok but the engine light is still on. So it seems that this problem is intermittent.

I had the codes checked at Autozone today (great place) and the error code read:

P2010 TAC Motor CKT Range/Perf


The guy at Autozone looked up the error on his computer and it read:

Control module throttle actuator position performance.

The ECM has detected the difference between the throttle valve actual position and the commanded position is more than a predetermined value.

Probable cause
1-Binding throttle valve
2-Faulty TP sensor
3-Poor electrical connection
4-Failed TAC motor

I guess that gives a good bit of info, but I'm not sure where to start.:confused: I've worked on cars quite a bit so I think I could handle this repair (famous last words).

But I can't even find where the linkage for the throttle valve is (is the throttle controlled by this motor and a computer? And if I do take the throttle body off will I screw something up even worse???):eek:

If anyone has seen this before and could point me in the right direction where to go first that would be great. Pictures would be great also.

Thanks a lot!

I'm actually in the same boat. I first took off my throttle body and cleaned it, that helped for about a week, now its running worse then ever and I cannot find a replacement throttle body that actually fits my car.
