Update:
Coder reader stated I had a bad Motor (I forget the exact code) and since I had bought an M35 Rear Steering Rack, I replaced the Motor. Code cleared.
Kept getting the code that says the Main and Sub Rear Angle Sensor Voltage Difference was greater than 1 volt.
I tested and retested the Rear Angle Sensor. I also tested the M35 Rear Angle Sensor. Both measured the same and looked the same except for the connector.
M35 has a 6 Pin Connector. M37 has a 4 Pin Connector. You can buy the Connectors, Inserts, Extraction Tool, Insertion Tool, Crimping Tool and it is all alot of cabbage.
So I bought a 4 Pin Connector at a local parts store. Looks similar to a Trailer Wiring Connector. Got up the courage and spliced, soldered, and insulated the wires with heat shrink tubing on the M35 Sensor and the M37 Wiring Harness. Code cleared and has not come back. I have driven the car on 7 different occasions for a total of 75 miles. I would have driven it more but the Y Pipe has a small exhaust leak. I am in the process of acquiring Sport Mufflers and all components from the Cats back. Some new, some used that I am reconditioning (wire brush, rust converter, Hi Temp Primer, Hi Temp Silver Paint).
It looks like the root cause problem has been the connector all along. The question is: Sensor side of the Connector? Car Wiring Harness side of the Connector? How they mate together?
I spoke with an out of town Infiniti Parts Guy (Sport Muffler and other bits) and he said the Connectors are problematic. He said that Infiniti insists they replace the entire Wiring Harness. Sometimes they just change out the connector. Interesting.
