Yikes. On the 05 and 11 schematics the knock sensors get their source voltage straight from the ECU/PCM. If that signal is not grounding completely out and is only pulling the source low (not enough to be a short to ground just low resistance to ground) across a low resistance it would be causing all kinds of issues with the PCM bus voltage throughout where ever that voltage is commonly used internally. Likewise the TPS also gets its voltage source from the ECU/PCM. I would guess the IAC may as well though there is no IAC on the 05 or 11 being they are throttle by wire setups. I just hope that has not damaged the ECU/PCM unit internally. If it has this would be one of those extremely rare moments where I would encourage someone to disclose who did the work so others do not fall victim to their lazy and pathetic work ethic. That is not an oversight. That is a rush job by someone who didn't care at all.
