Haltech/ GM TPS part number ?
 

Hello,

Does anyone know the part number for the GM throttle position sensor ( TPS ) that haltech uses .

I believe I found the item at a gm dealer, but i want to see if i can find a same product somewhere else other than dealer. ( he didnt want to give me part number )

Thanks

WTF??!!??

I posted a thread that had all the information on it, but its gone!

That pisses me off..

I did a search coulndt fidn any part numbers.

If you have a part number could you pm it to me :) .

I *think* its the 71320, shaft actuated GM style.

Guys, there is no need to use the Haltech specific TPS, you can use any 0-5 potentiometer. If you car has a TPS like this dont worry about getting the GM one.

I always prefer to use the car's own TPS because there is less chance of error from miss calibration or a bad adaptation/fitment. But, if you car is like some toyotas or VWs where the TPS voltage goes from 5-0v you cant use it, or, you might want to reverse the positive and negative wires to see if it works right.

that would just be -5 to 0 then

What do you mean? Ive never tried it my self, reversing the pos and neg on a TPS to reverse the signal.

But ive been told it works.

It's like taking a volt meter on a battery and switching the leads.

Most tps work off a potentionometer (sp).

It puts a set voltage across a variable resistor (varies with position) and then the voltage is read across the resistance.

So you would use a Series 4 FC TPS?

No, you need the full range TPS from the S5 dual TPS. The S4 TPS doesnt cover the whole throttle travel.

That was where I was going with that..

I just did it recently, put an S5 TPS on an S4 throttle, and it works just fine.

I am not doubting that, but you said:

I wanted to clarify for anyone that is new to the Haltech, or EMS for that matter, that the Series 4 TPS is a worthless peice of junk..

Thanks for the info J-rat.
Yes i adquired a S5 tps, Then I found out that the '' magic '' is not actually in just the tps , but also in the special claw the S5 throttle bodies have. I threw out the S5 tps bracket, so know cant really do much.

So now im looking for a TPS that will work as when Im 1/4 throttle the ems reads 99% .

There is one catch in using the S5 TPS on the S5 throttle body. You need to take off the one that is furthest from the screws and mount the one closest there. Ill try to post a pic of it here if i can later. The TPS are held on the braket by 6 (sort of) pins that you can bend back to take it off and re attach later.

The 0-5v TPS is the one with the blue, pink and yellow wires.

Okey,

It seems the part numbers supplied here are for aftermarket tps . Would anyone know what car ( year if possible ) this tps is off of.

The part number that was placed this is an Electromotive part number, you can just use the FC series 5 5v TPS like ive described.

PMed

Will try to post a thread on using S5 TPS, i just havent had time.

Later,

So anyone, I have tried contacting haltech and no luck, So i guess i will go with the electromotive.

But one more try, anyone know what the GM part number or vehicle its off of, all the info I got is its off a GM truck.

Try pontiac brand, from around 1987.
