    Arrow my Phantom Codes (?)

    These 4 codes are set as permanent despite multiple erasing's and test drives.

    They are not causing the engine light to be illuminated or any drivability symptoms I am aware of.

    I call them "Phantom Codes".

    Any info ??

    If a permanent code is already set and you then go and disable the code that enables the diagnostic to run, it will not clear the permanent code, it will do the opposite - cause the permanent code to NEVER clear, even if you correct the condition that caused the code. The test(s) have to run and pass a certain number of times before the code will go away.
