Does anyone happen to have the P/N or the correct size and length of the torx screws that hold the Throttle Position Sensor on the Throttle Body???

This is for a 93 LT1

Thanks

I don't have the P/N, but if all else fails, have a machinist make up a bolt for you. I've done that before.

 

The only way the parts book lists them is in a "bolt kit" and it does not give any information on the size of the bolt/screw. I tried to find this before for Injuneer.

The bolt kit is GM PART # 17113098, which is basically all the small bolts on the TB.

 

Thanks guys. I'm not ready to pay $20 or so for the kit, but I'll save that p/n for a last resort. I'll try pulling the one bolt that I have left (head snapped off the other one) and take it over to W W Grainger and see if they can match the thread dia and pitch

 

Good idea. Post back the specs if you can, so others will have it, if needed.

 

Gimme $2.00 and i'll ship you some out. I've got so damn many of these botls and sensors, it's not even funny.

I'll bet you do. I should have thought of that.

 

I'm gonna have to start nickel plating them and putting them on ebay as a kit

Thanks for the offer NOMAD, but I was looking for a more immediate solution than snail mail

I did eventually find the dimensions of the screw though.

It's 4.5 MM x .75 pitch
17mm long (thread length w/o the head)

Unfortunely, that is a very odd screw, that not even most bolt houses carry. I was told that it was basically a fine thread metric screw, so it was the pitch that presented the problem - no real demand, so very few stocking locations. After checking around with 4 different places locally, I decided to give up, even though I did have a few more leads. (If I had kept driving around searching, it would have been about as expensive as just going over to GM and picking-up the TB screw kit. )

Anyway, I ending up tapping the holes in the TB for a more standard size screw.

That's for the help guys...

 

Hello, i was changing the TPS on my 96, and i dropped on of the bolts in to the engine bay. spent a hour looking for it and can not find that sob anywhere. i know it comes in the 17113098 kit, but all i can see of that is no longer availbel at the dealer. any one know where or who might have one in the lower mainland of bc?

 

Hope you can find the bolt that you need, but the kit is still available at every GM place I look at on the internet.

 

Yeah ive seen it online. i was just hoping to be able to get for tonight so i can get the car going again. Ill proble end up spending a few hours this weeking with a mirror and a magnet searhing.

 

The top plate does not contain much in the way of vacuum or pressure. It flows air from in front of the throttle blades to the passenger side valve cover, for the PCV system. Put some O2 sensor-safe RTV on the plate/gasket, and tighten down the 5 screws that you still have, for a temporary fix. Just don't leave out one of the corner screws.

 

Another question. How do you test the volts on the TPS?

i looked on shoebox's site and i didn't see it.
