Answer 1

P0122 Accelerator pedal pedal position sensor signal voltage too low

P0500 Vehicle speed sensor signal

P1693 DTC (diagnostic trouble code) detected in the PCM

P1693 happens when the battery has been disconnected  P0122 you need to measure for 5 volt reference at the APP. If the 5 volt refernce is at APP replace the APP, is there is no 5 volt refernce to APP replace the ECM
