Answer 1

P2106 Electronic throttle control Forced limit power

P2127 Throttle pedal position sensor switch "E" circuit low input

P2138 Throttle position sensor "D/E" circuit low input

Your electronic throttle control system is made up of 2 components, APS1 which is mounted on the thrtottle body and APS2 which is mounted in the accelerator pedal. The PCM judges the current opening angle or the accelerator pedal APS1 and APS2 if there is a signal difference between APS 1 & 2 You code up P2138. What can set these codes, poor contact by terminal connection,or corrosion on the APS contacts, What you need to fing and resolve this is problem is a scan tool that can read APS data 1 and 2, or even a labscope that has 2 channels
