Bigtime update on my torque converter clutch solenoid problem.
I must first though admit to my own ignorance!!
When checking the resistance across pins 3 & 4, which is mentioned above, I unknowingly was checking the wrong pins! After looking at everything, reflectively, I noticed that the connecter was upsidedown in the image of the PDF file that I was referenceing. Why this was not noted I have not idea, but it could be verified by looking at the connector in the drawing and reference the tabs located on the outside of the connecter.
Anyway, now that is overwith (taking a deep breath!), I had time this afternoon to recheck the resistance and found that it is measures exactly 2 Ohms. This verifies the confusion as to why my connecter is black! Remember, I said that the low impedence solenoid body had the black connecter and was phased out during the 95 model year. During that same year, a new high impedence solenoid body was introduced that had a beige (natural) connecter. All CD4Es from the years of 93-95 can have either solenoid body with no adverse effects. Put one of the low impedence solenoids in a post 95 CD4E and there will be problems. It also verifies what Roadrunner was telling me in the end, that the code was being generated because the PCM was not senseing the proper amount of resistance from the solenoid, hence the code P0743 once the car reached open loop operation.
So that is pretty much where I am right now. The car still runs good and gets very good gas mileage (29-30 mpg), but most importantly I wanted to get this out to everyone so that it can be referenced in the future.
Thanks again to horseydug and Roadrunner for all the help in troubleshooting this problem. If not for them, I would still not know a single thing about this subsystem of our CD4E.
