    I recently replaced the throttle position sensor on my '88 Accord.
    According to a recent posting by Jim Beam about fixing TPS's, after you
    replace it you need to reset the computer. How is this done? For that
    matter, where is the computer?

    If the 88 Accord is the same as 94 Civic(I'm not sure they are)
    The Civic has a under hood fuse box left side near the firewall.
    (Standing in front of car, looking at firewall). If these fuse
    boxes are alike there should be three fuses along the back of the fuse
    box. The middle fuse on the Civic is marked "backup" and is 7.5 amps.
    This fuse kills power to the computer thus resetting it. If you do
    not have an anti theft radio (do not have) you can just disconnect
    the negitive post to the battery.

  3. Assuming the procedure is the same as with my '93 Accord, you only need to
    remove the "back-up" fuse for about one minute, then put it back in. Note
    that you will have to re-enter the clock time and radio presets.

    I think the computer in your Accord is located under the driver's seat.

    Actually, that fuse also supplies the constant power to the stereo and
    the clock (in the '94 Civic, anyway), so if your stereo has an anti
    theft feature, you will need the code to make it work after resetting
    the ECU, regardless of whether you disconnect the battery or remove the
    backup fuse.

    Randolph, you are right again:). I just checked that fuse in
    my 94 Civic and it does indeed turn off the clock and the radio.
    My manual said that pulling that fuse would reset the computer
    with no warning about a anti theft radio or the clock. A former owner
    had installed an after market radio so I did not have the anti theft
    problem anyway. Thanks.
