View Full Version : TPS sensor needed, urgent, engine dyno in under a week

03-04-05, 11:59 PM
Hi, i have a nissan VH45 100mm throttle body on my SR i made a custom throttle linkage ets as it came with out tps and with out linkage.

I am trying to fid a tps to go onto it, the bolt spacing is 48mm (same as s13) but the rotation is opposite to a s13, also the shaft is D shape and is 8mm in diameter.

I seen haltech make a tps that is either cw or ccw but cant find its bolt spacing on there site, or anything about it for that matter on there site.

I looked at the bosch ones and they dont seem to have one to fit either

Thanks for any help trying to finish motor as the engine dyno is in a week!

roatation looking at it in the pic is ccw

It shouldn't be too hard to build up an adpater to fit a Haltech sensor, the bolt spacing doesn't look quite right to me.

Edit - Something like this (http://au.farnell.com/jsp/endecaSearch/partDetail.jsp?SKU=4246676&N=401) should do the job (a little cheaper too).

Can your ecu read the sensor both cw and ccw?

autronic can do what ever cw and ccw

i didnt even think there wa sa difference all it is is a linear voltage out put with throttle position, cw or ccw wouldnt have a different reading i thought. Just the physical direction of the tps its self

So the S13 shaft is different but the bolt spacing is the same?

yes and it also rotates the wrong way. i have bought a haltech TPS should have it in 2 days, can rotate both ways by just flipping it so ill just make up an alloy adapter bracket and should be all good.

so the autronic can't read the voltage going backwards?

The problem would be that the TPS would have a spring return and a stop at one end, so they only really go one way..

This is what I use with my Motec:

Just flip over to reverse direction. Gone up a bit in price since the last I bought tho...
