Yea some guy told me about that too but i was told even if you unplug your pos terminal for 15min it still wont go away. He told me to go to Mitsubishi and have them clear the code with some scanner they have that cost 10grand. I kep trying the pos terminal with my car and the check engine light keeps coming back but mine is for the tps sensor. any1 know how to adjust these damn things or should i get a new 1?
