    If it is a newly manufactured wiring harness - then it should be OK - as long as it was wired (pinned) for a Camaro APP (pedal).

    Make sure the APP that you have is for a 2010 to 2015 Camaro.

    You may have a wiring issue, or a mismatch between the ECM, throttle body, and accelerator pedal (APP) being used - or all of the above.

    You may also have an OS mismatch between the ECM and TCM. ...

    The PCM must be fully programmed with a 2001 or 2002 Express / Savana L31 5.7L calibration. I do this using GM software, you could try the "write entire" option using HPT.

    PE delay parameters - time, temp, and RPM - are available in the 1999 and 2000 OS. It is the ramp in / out rate (i.e. rate of EQR change) that was not available until 2001.

    The 1999 and 2000 P01 operating systems were unique. Perhaps most notably is that they had a Main VE table and a Backup VE table. In 2001, the P01 operating systems were updated and improved.

    The P0700 and U0100 DTCs mean that the ECM and TCM do not communicate properly. This happens with a mismatch of parts or operating systems.
