Subject: Re: Code 33 Saga Continues... by Schrade on 2015/3/31 13:30:13 Excellent job diagnostics. Take time to write up, post, think about it, is when stuff comes to ya'. We get WAY too used to instant point n click, and don't take time to think it out. When you tested the Ground Circuit, "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." , was the ground jumped (to Closed) by your by-pass test wire? DEFINITELY good diags so far. Can you shoot a snappic of each step? THis sometimes give another 'angle' of thought to diags process... Does DTC 33 DEFER TO another DTC, if present? With a relay in the circuit, do you have to 'activate' the relay, with a jumper, to get the MAF circuit to close, for testing? |
