I checked everything, and still havent found someone to scan my VR6 since its an OBD1. I do not own one for it. However, i did notice that when you disconnect the TPS nothing happens it remains the same. When you connect it back up, nothing happens and it continues as if it did not exist! If you unplug ISV it will stall. If you unplug MAF it stalls. Sooo, i know they are working they are bran new! But what would you guys say about the TPS?
