THROTTLE ACTUATOR SYS/ STUCK CLOSED. I cleaned my throttle body by the step by step instructions in the DIY and now I get this code P2112. What do I do? Help...

 

Did you remove the TB to clean it? If not, did you Goober on the sensor? You may need to clean it off now...


I know this is going to come as a major shock to many here, but I am not perfect!
I took the lazy route the first of the two times I've cleaned mine and did not remove it. Yup, I goober'd on the sensor and had to remove the damn TB to wipe the sensor clean. I removed the TB the second time I cleaned it...

 

Yeah Hammer, I took it off to clean it but I made sure nothing touched the sensor. I'm guessing it just had to reset itself or something because immidiatley after it happened I came inside and got on this site to see what the code was, and by the way unless I missed it that code is one that is not listed, I did a search and found another thread about it. I posted the thread asking for help and went back outside and tried to start it again and it did the same thing,rough idle and wouldn't accelrate over 2k rpms. I shut it off and checked the codes again getting the same P2112 so I tried to start it again and it idled high and shut off. So now I'm worried, I tried it once more and it started like it was supposed to and ran great! I closed the hood and took it down the road for a test run and it was GREAT! SO I don't know what happened but, as stupid as it may sound to some, THAT my friends was my experiance cleaning my throtle body! Thanks for the input to HAMMER.

 

It's probably fine then. My guess is the PCM got a signal right after you cleaned it and attempted to compensate making it run like crap. Once the the sensor returned a normal, the CEL went off, the PCM adjusted for it and business as usual.
If it comes back, manually reset the PCM and see what that does...

 

will do! thanks HAMMER!

 

Yeah ecu's are funny things.
