Here's an update. I bought an Innova Code Hammer OBD2 Tool. It read codes P2112, P2104 and P2111. I disconnected the air intake hoses to access the throttle and cleaned it with Throttle cleaner, giving it a wipe down and manually manipulating the throttle gates to ensure they were not stuck. Then cleared the codes and ran the engine. Codes P2112 and P2104 reappeared and the throttle is still non-responsive. Next step is to replace the throttle body.
Did you try to recalibrate the throttle body to ECM?
Here is a Youtube video of the sequence..
Recalibrate Throttle Body VideoThis step will reteach the closed through open values to the ECM..
Barring that, not sure if manually moving the throttle plate was a good idea. The correct way to clean the throttle body is to use the key on but engine not started and then have someone hold the foot feed down to the floor (which opens the throttle plate).
IF your code reader is able to read LIVE DATA, you should be able to read the ECMs TP values from closed to open with key on and engine not running. If TP values change then it just may need the calibration sequence done..
IF you do go with a new throttle body, chances are you WILL need to do the calibration anyways so I would do that BEFORE committing to a new throttle body (remember it WAS working before the battery was removed)..
