    Default Error code

    Have a hard code of ECM-P06A3. Reflashed and the first run everything is clear but code returns on restart. Can I get some help on how to fix?

    GM says EGR position sensor. Not understanding why after reflashed it only throws code AFTER shut down of first run. If it is position sensor why doesn't it throw code DURING first run? Or is it EGR sensor?

    Ah ok, although this link is to a Cruze the DTC numbering is consistent across all GM vehicles. Unless they mean your EGR position sensor is bad and is causing the 5V ref error.
