Throttle non-responsive after batter disconnect

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.
