How do you adjust t.p.s

Does anybody know how on 89'dx?

i don't think you can adjust it. all it does is that it senses how much throttle you are giving it and then sends the info to the ecu so it can adjust the fuel,air,etc... i may be wrong, but i'm pretty thats what it does.

There is no adjustment for the throttle position sensor. Why do you think you need to adjust it?

89/96Si,

You have a grand national? You are the man! You will have to bring it up to atlanta dragway some friday night.

There are ways of adjusting it... However you have to file/grind a groove/slot or something like that, in order to get a screw driver on the bolts.

If you pull it off then drill holes on either side of the ones that are there. that way you can turn it will in the car. It wont do mutch for you by adjusting it, and usually it is set to read close to .5V at idle, you cant go over that. what you want to do is to increase the voltage read at wot to give that extra kick you are looking for.

you can get all the info for that here. As well as other cool tricks to make your car go faster
