Hello again. I was hoping you would be able to tell me how adjust a throttle position sensor.
So I put an obd2 scanner on the car and I got three codes the first one being p0123 it says throttle pedal position sensor switch a circuit high. The second code is p0122 and it says throttle pedal position sensor switch a circuit low. The third and final code reads p0113 and it reads intake air temperature sensor 1 circuit high. Can you tell me what would cause these codes please?

Thank you Ken for your help. I replaced the TPS and that fixed the idle and cleared all but one of the codes. Now I just have the air intake temperature sensor.
