Throttle Body wiring diagram

Recommended Posts

Hi everyone. Ive been building a Corrado VR6 Turbo for the last couple of years and its about finished but ive been having problems getting it to idle correctly. Ive spent the last couple of months figuring it out. Vagcom wont basic set the throttle body and im getting weird readings in measured values. Ive narrowed it down to the wiring to the throttle body. Its an OBD2 setup with loom etc but ive rewired the loom as it all goes behind the wing now and got rid of the 42 pin round connector but i think ive got the TPS wiring the wrong way somewhere and was wondering if anyone has a proper wiring diagram for the throttle position sensor? Maybe from a bentley manual (my Corrado bentley manual only has OBD1).


This is where i think ive gone wrong. This diagram shows Pin 4 is a ground, Pin 7 is 5v feed for sensor and Pin 8 is not needed




But, according to this, Pin 4 is Sensor feed (5v), Pin 7 is a ground and Pin 8 is 'Sensor 2' to pin 62 on ECU.




Can anyone clarify which pins on the ECU all of the wires go to?
