    Service Engine Soon??

    Hi all. "The Service Engine soon" light came on my '03 Discovery, and I do not have an owners manual for the critter yet ( wasn't in the Rove when I got her).I would hope that it is seperate from the "check engine" light found on other vehicles. With that in mind, would oil, plugs, cap and rotor, air filter solve the problem, or am I missing something? Has 76.000 on the odo, so plug wires as well? Thansk in advance for the help.

    Well the "service engine light" in the D2 is the same as the check engine light in the D1. see if you can get the codes read. Is the truck driving sluggish

    You mean it's not supposed to be on all the time?

    Just kidding - don't start guessing on an SES. Head to Autozone and get the codes read. Then you'll have an educated place to start.

    And I could be wrong, but I'm pretty sure your 2003 doesn't have a cap and rotor ... I've been wrong before though

    The first thing you could check is the gas cap. If it's not fully tight it could trigger the SES light (something with the vapor codes). Happened to me a month ago, I still had to pick up an ODB2 code reader ($60 at wal-mart) to clear the code.

    good luck! nate

    Ohhh Kaaaaay... I ran the codes and came up with P1481, aux emission control, P1174 control fuel air, and a pending P1171. Joy o joy, just in time for a graduation I have to be at in Bakersfield Friday. Guess I'll be under the hood between my workaday until then, any suggestions?

    check for vacuum leak. If there is no leak it is most likely the mass air flow meter. part number is mhk100800 and retails for 248.71 . good luck
    Buckle up I want to try something!
