GM TPS Conversion

[parrisw]

The TPS that came on my 3.9L intake was no good, so they require a remortgage of my house to buy one at $700, which is the most ludicrous thing I think I've ever seen in this automotive world!!  I mean who in their right mind would bloddy well pay that? So seeing as I can buy a GM sensor off the shelf for $30, I figured I'd come up with this simple conversion! Easy peasy!


Sensor Napa part # UNI 219187
Sensor Connector Napa part # UNI EC89

Sensor with Connector,



Underside



Bolted to intake, required slight elongation of mount holes.



Start of machining of a drive tang, this is the end that goes in the TPS.

Installed in TPS to check fit.



Turned other end down ready to machine flats.



Flats machined on each side to fit into throttle shaft.



Ready to install!

Bravo!

Are the resistances suitable?
