Alright, i'm going to apologize for the long post first. I have been searching and searching trying to find what's going on and these forums are a lifesaver so thanks in advance!!
The issue that i'm having is that I have Signal Return when clutch pedal depressed but as soon as i release the clutch it goes away....below are my troubleshooting factors.
I have an 89 5.0 manual vert. The check engine light has been on for a while and i've been doing some investigating to see what the problem is. Did the self-test and got codes 51,22,53,54,35,67. I ruled out that they all had something to do with the Signal Return (Pin 46), so i took the ECM out and checked for a burnt trace. The EEC-IV that i have is a A9M and it looked fine inside. After searching more forums i found out that the 02 sensor harness "jumper" has something to do with it. Since my computer is an A9M (Auto) and i have a manual transmission i figured i would do the swap that everyone was talkign about on the 02 harness. Swapped the jumper from manual to auto and i now have Signal Return from all Sensors, however this is only with the clutch pedal depressed. Has anyone heard of this???
As soon as i let the clutch pedal out the signal return goes away. I ran the self-test again after getting the Signal Return taken care of and i received codes 22,and 67, with the clutch pedal depressed. Upon further investigation last night i noticed that the Light Blue/Yellow and Black/White wires that come from the Clutch Switch and go into a connector near the center console under the dash didnt' have anything connected to the other side of it. Is this normal? I searched and searched for the plug that mates to the other side of it and can't find it. Please help!!!
