TOR4x4 Posted October 6, 2010 Share Posted October 6, 2010 I've converted the inlet on my 5litre to D2 bosch system, everything else has swapped over ok now, except the TPS. Does anybody know which pin is 5V in, Earth, and the signal output. Rave isn't clear which is which. Thanks Adrian Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted October 6, 2010 Share Posted October 6, 2010 Measure it with a multimeter - two pins (probably the end ones) will have a constant resistance between them, the other pin will vary relative to the other two as you rotate it. This one is the signal. The other two are +5v and GND, you need to wire it up so the voltage on the signal pin increases as you open the throttle.

TOR4x4 Posted October 6, 2010 Author Share Posted October 6, 2010 That was quick. Pretty much what I found. Wasn't sure how critical it was on getting the GND and +5v the wrong way round and releasing smoke. Thanks for the help I will investigate further.
