    1998 E320 Fault codes

    My engine light just came on and the message "check engine electronics"
    flashed on the display. I hooked up the computer to it and the codes PO170
    and PO173 came up. These are defined as "fuel trim bank right" and "fuel
    trim bank left". Could anybody please enlighten me to what those codes
    really mean and what do I have to do to fix them?

    Thank you in advance

    From memory I think these are for self adaptation reaching min/max
    limit on each bank of cylinders. This is to do with mixture control.

    You need to get the self adaptation values reset by your dealer, they
    do this by "boot strapping" the control unit. Hopefully this is the
    last you will hear of it, most of the time its just a temporary glitch
    and it won't re-occur, but if it happens again then its head
    scratching time...

    One cheap thing to do is check your gas cap. If it is not on tight it can
    cause these types of errors. Also, I had a friend who had this problem but
    it took 100 miles or so of driving to clear the "Check Engine" light.
