Answer 1

P0123 TPS / APP circuit high

P0113 Intake air temperature Circuit high

P0201 Fuel injector 1 Circuit

For this start out why the TPS is circuit high, the IAT code even if that is circuit high condition that you would need a PCM just to tell you that there is a problem with the IAT sensor. Circuit high codes occur , when there is no connection of that sensor. When this code occurs clear the code if the throttle response return suspect the TPS as the problem
