Replaced throttle position sensor- reset computer?
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? |

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. Ernie |

For that > matter, where is the computer? > 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. |

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. Ernie |
