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.

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.
