any oem D shaft tps sensors?

Whizbang · 05-30-2010, 01:49 AM

im pretty sure my haltech tps is screwed. With the accel enrichment table up on the MS and even without the engine running, i see readings from 9 %/s to even 200 or more %/s without touching the pedal.

Its causing a lot of low speed bucking and poor running due to the acceleration enrichment activating.

so in lieu of spending 100 dollars on another haltech tps, is there something i can get from a junkyard? I really dont have to modify my throttle body shaft to accept something like a blade type GM sensor.

Why mess with OEM crap?
That's exactly what the Haltech unit is...
It's a Ford unit with a GM Weatherpack connector splice into it.

Try a MoTeC TPS unit...

i honestly was trying to aviod spending 100 for a new tps.

i sourced a few options from the junkyard. The fords seem to be blade type, or at least the ones i came across. As were GM.

I believe I spent around $40 or $45 for mine, which mounts directly to the EFI Hardware/Tweakit throttle bodies.

Although on further inspection, the two people I knew who had them for that price are now running ~$100. Odd.

For a slightly more junk-yard approach, I once used a 420A TPS from a neon by filling the input shaft socket with JB Weld, and then pressing it onto a plastic bag covered d-shaft on my throttle bodies. It worked for quite a long time, too, actually.

did it bolt directly? i have the efi hardware throttle bodies as well and had to make this silly adapter bracket to make the tps i have now fit.

No, I had to make an adapter/spacer plate about an inch thick to bolt to the throttle bodies, and then for the TPS to bolt to.

yea i just went through that. whats kinda weird is that i dont seem to go through the entire sweep of the tps

its read well inbetween where the haltech one readas. which is odd. not sure if the hyundai rotates more or something....

I had that issue, too. I ended up just centering it such that my full range of throttle movement was inside the TPS's, then calibrated it in the Megasquirt, and it went happily along it's way.

i calibrated it but it has immedately started to run worse with this tps.
