AUSBen31 Posted June 21, 2021 Report Share Posted June 21, 2021 Hey guys, Another issue im currently trying to work out. I have installed: Nissan Attesa 4WD TPS Adaptor Part Number: HT-038001 to correctly send the TPS (MAIN) signal to the ATTESA ecu. Upon installation as per Haltech's supplied instructions: Pin 1: 12v (ECU power) Pin 2: GND (ECU GND) Pin 3: TPS Input (TPS (MAIN) ) Pin 4: TPS Output (Pin 37, Throttle opening signal 4WD, rb25det neo stagea S2) Measuring with a multimeter, i can confirm the TPS input matches exactly what is displayed in runtime values. However, the TPS Output has no reading, connected or disconnected from Pin 37. I would have assumed being a 1:1 adapter according to Haltech it would also have the same voltage on the output? Am i safe so assume if this is the case, that this item is DOA? Or am i going about this the wrong way. Thanks, Ben Quote Link to comment Share on other sites More sharing options...
Vaughan Posted June 21, 2021 Report Share Posted June 21, 2021 Haven't used one of these before myself but it should just be a super simple circuit and I would expect that a multimeter measuring voltage between pin 2 and pin 4 should read the same as between pin 2 and pin 3. Maybe contact their tech support to see what they say. Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 21, 2021 Report Share Posted June 21, 2021 Yes sounds like it is dead or has no power. You should see basically the same voltage on the output pin as the input - the output is just a high current capable signal of the input.

AUSBen31 Posted June 22, 2021 Author Report Share Posted June 22, 2021 Haltech tech support seemed to agree completely and have express sent another one out. Will update thread with a result. Quote Link to comment Share on other sites More sharing options...
AUSBen31 Posted July 17, 2021 Author Report Share Posted July 17, 2021 Update to finish up this thread. Haltech sent me out another TPS adaptor, found the original to be DOA. With the new one plugged in, vehicle has 100% working ATTESA. Just bad luck! /thread Quote Link to comment Share on other sites More sharing options...
