Throttle body won’t open !

[Jap350]

Hi, driving to work car randomly went into limp,  found out throttle body won’t open and I have throttle body codes 1122 and 1126. Car won’t rev past 1500 when warm. Stuggles to start due to throttle body not opening. I have replaced ipdm as it was badly corroded no change. I get response from pedal position sensor and throttle body when manually opened in live data. I have tried a new throttle body aswell and no change. I have also checked power to the thottle body connector I have one wire that gives power with the ignition on. I have cleaned all earths I can find and checked any loose wires or corrosion on any connector related and the ecu. Any ideas where to go next ?
