Subject: Re: Code 33 Saga Continues... by CorvetteBob on 2015/3/30 0:44:58 Again, this is an '86 4+3 coupe. To add some clarification of my progress I've been following the FSM trooubleshooting chart for Code 33. So far I've; With IGN off, disconnected the MAF run a jump wire from "G" of ALCL Terminal to MAF sensor harness terminal "E". Checked w/ 12v test light. Test light"off". Disconnected MAF power relay and probed terminals "E" and "C" (ckts 340 & 120) with test light to ground. Light was "ON" on both. Then probed terminal "B" w/ test light. Light was "OFF". It now says I should repair open ground circuit. (I don't know where that's hiding). At this point (just out of curiosity)I used a continuity tester to check my ground. The BLK/WHT wire (ckt 450) I think. touching the continuity tester to the blk/wht wire at the MAF power relay and at the alternator bracket, I got continuity, making me believe the ground is intact. BUT AM I WRONG? I don't know, my strong suit has never been troubleshooting. Any help is appreciated. |
