Okay so here's my dilemma, I'm running a Q45 tps on my rb25det neo. I've been trying to set the tps to approximately .45-50v. I have no problem setting it to that range. The issue I'm having is that when doing so it runs it in open loop. The closed loop flag will not "engage" unless i drop the voltage down to .35ish volts. Why does it have to go so low? is the tps fault? do you think its worn? otherwise it seems to be running fine....
