Subject: Re: Code 33 Saga Continues... by CorvetteBob on 2015/3/31 1:08:34 So far my source for the troubleshooting has been the 1986 FSM, page 6E3-A-50 and 6E3-A2-51. The first of these is the initial page for Code 33. The other is the troubleshooting flowchart. In noticing the circuit #993 to the MAF was dead, and without continuity from relay to sensor, I ran a jump wire from the MAF power relay at "A" over to the harness to plug into the MAF sensor into "E" , thereby bypassing the purple wire circuit #993. With the codes cleared from the ECM, I then started the car. It started and ran fine. The result was the Code 33 was not showing any longer. I think at this point I need to get in and physically trace the purple wire 993 to assure that it does in fact run directly from the MAF back to the power relay without interruption as shown in the diagram on the 1st page listed above. If that is the case, I"ll build a new wire and replace the old wire. As an afterthought , before I do that, I'm gonna double check the FSM wiring diagram in the main diagram section to make sure the two diagrams concur. If any of you discover I'm on the wrong path with this, please chime in. I wanna make sure I get this right. |
