    EEC iv codes 21 24 63

    What's up all
    When finally got time to work on the 90 wagon
    And it's idling like crap, and pulled 3 codes 21 24 63
    .
    ECT out of range cold engine?? Code 21
    Iat out of range air temp ??? Code 24
    Throttle position sensor to low code 63...?...

    So doing the EEC test on a cold engine will cause the first 2 codes??
    And code 63 check for what?

    pretty much... cold engine codes except for the 63. check the TPS for proper function. Backprobe with a multimeter and see if it's crap or not. Check the harness for proper connection too.

      Yeah you gotta drive it and get it up to operating temp before you do a scan.
