First, I'm not sure if this is the right forum to post this issue, so I do apologize. Second, I posted about the problem that I'm having with my 02 with the throttle system giving reduced engine power. I replaced the pigtail connector to the tac motor and still giving me the codes. ok, long story short. I'm attempting to clear the DTC codes, but the only light to go away is the Traction Control light, only to return and go back into reduced engine power when I restart the truck. I did the continuity test with my DMM on the tac motor connector, TPS, and MAF (not sure why I did the MAF lol)... test is good. I'm starting to believe that the ECM is bad, but not 100% sure. I've seen that an ECM software upgrade corrects the P1516 and P1518, but I have other DTC codes as well (P1120, P1220). Any ideas?
