2006 Chevy Impala "Reduced Engine Power"
Back in December i first recieved this error on my dash after setting the cruise control for 30 minutes or so. I was unable to go over 40mph and it was rough running. Brought into shop they cleaned the throttle body but said it was not a permant fix. Things were good until a few weeks ago when the problem came back but worse now I can't go over 20 mph.
The codes are: P0455 P1516 P2101 P2135 I have a new throttle body on the way tomorrow but was beggining to second gues that this is the actual problem as I see it can be several things that throw these codes. Please help |
there is a tsb for cleaning the t-body when this codes sets; so performing that step was a good first step.
3 of the codes are all throttle body or throttle position sensor related; so as long as the wiring is ok (there is a tsb for chaffed wiring) you will probably be ok in replacing the part. the po4XX code is evap related and has nothing to do with the reduced power message. |
Ya looked at the wiring earlier today everything looked fine and tight even the ground. Hopefully my problems are over once I put the new one in.

The 2101 code sets when there are problems with the throttle position sensors within the throttle actuator at the throttle body. I recommend consulting with a certified technician for an official diagnosis and repair option(s). Please keep us posted. If you have additional questions or concerns, please feel free to contact me privately. Louis GM Customer Service |
2006 Chevrolet Impala engine problems
My name is k Navarre;and I have a 2006 Chevrolet Impala Ls, it's a 3.5 liter V6 and it runs really rough after the "reduced engine power" messege comes on the instrument pannle. We've changed the camshaft sensor, the throttle positioning sensor, and the throttle body itself, and the engine reacts with the same dissabilities as before these parts were changed. I need to know what the problem with this car is because my wife and I almost had a really bad accident because of the engine shutting off trying to cross an intersection. I don't understand why there isn't a recall... Please help us feeling stressed out
