I feel like a dumbass posting this but I adjusted my TPS last night and I guess I did not tighten up the nut on the back side of the screw. So it is missing when I got to work today and looked under the hood. Does anyone know what size screw that is. I went to Lowe's and a M5 looked right but the standard .8 pitch is wrong. Is it metric or standard? I can't find any fine thread metric nuts under M8. Thansk in advance.

I was not aware there was a nut on the TPS adjusting screw..?

There is a locknut/nut and lock washer on the backside of the adjustment screw that prevents the screw from backing out of adjustment.

ya my old car did but not this one, but ive never had it vibrate loose or anything
that spring provides enough tension i think

i think it's the same pitch as the throttle plate stop screw (which affects idle). And that's a super fine metric pitch. you will probably have to go to the dealer.

I was hoping I could find out what thread it was so I could just tap a new one, it looks to be a M5 x .5 but I have no way to confirm. If I call the dealer they may be able to tell me.

don't even waste your time calling them. go over there and physically look through the diagram with the guy.

Same thing happened to me and the deal wanted 60 bucks for the new arm assembly.

Yea i just called the dealer and they can get me the part but it comes a a 4 piece set, spring nut washer and bolt for $45 + shipping. So I am trying to see what else I can do. I am going to take my micrometer adn a pitch gage and find out what it is when I get home.
