Unsure of relationship of p0083 and disconnecting battery but below is the diag chart. Hope you can read it as some times pix do not go through. All indications are you still have a problem with one of the crank sensors, Ignition module or wiring. The only way to find out is to follow the diag tree. Really no guessing permitted on this one. I f I had to? the ignition module maybe.
FAILURE CONDITIONS 24X signal at a logic HI and no 24X reference pulses received since last CAM pulse.ACTION TAKEN PCM turns "ON" the Malfunction Indicator Lamp (MIL) (Service Engine Soon).NOTES ON FAULT TREE (Part 1 of 2)
If you have run the above test step by step it had to lead you to something that is causing the po 83 code unless it was/ intermittant problem. Considering the cluster is controlled by the BCM and the sensors etc for engine are PCM probably not but anything is possible when it comes to bad grounds etc..If you accurately followed the above test and hit the end with intermittant fault. nothing more you can do till it becomes a hard fault or you catch it in the act,
I really do not have any answer. Where is the diag chart taking you after you do all the jumper tests?
Like you, I have pulled amny a dash and anything could have happened. A wire broke, got pinched etc. I just do not have an answer to this problem. Are you sure the light was not coming on before?
It leads me to test the resistance on terminal E. In all the time that I had it running prior to reinstalling the dash it did not set the light. I drove it for 20 miles after it was put back together with no codes. I have repulled the dash, ran a jumper to the PCM, load tested the wires, replaced the crank sensors. I am pulling my hair out on this one. It seems to be worse when it is cold. I used my choke tester to cool the ignition module to see if it caused the code to reset, it did not. This thing is eating my lunch. I ma ready to take it to a dealer and tell them to fix it. It has taken over 10 hours of my time in the past week and the module has a $457 price tag. I would hate to install it and have that not fix the issue.
