T750 Crankshaft position sensor error E000636-02

[Mack2859]

I have a 2014 T750 high flow. I have been getting the error E000636-02, Crankshaft position sensor error, for a while now. It has gone back to the dealer several times for repair and the error persists. The following have been replaced:
Crankshaft position sensor
Wiring harness
Starter
Primer fuel pump
All filters

The unit runs for a while and then it throws the error. RPMs drop making it unusable. What I find interesting is that the error doesn't get stored in the history.
This is a Tier 4 Kubota engine. I am at a loss on what to do next. Despite the dealers efforts, it still does it.
Any help would be appreciated.

Do you have your Serial #?

Which harness was replaced? Because there are 2, one from the ECU to the ECU Harness and then the Ecu/Engine Harness.
If you look on the PDF I attached, it is either Part #11 or #41. Which harness was replaced?

 

[Mack2859]

It was the engine harness. Part #41

It was the engine harness. Part #41

So it could be still the harness Number 11. Do you wanna check it yourself? I can look up the electrical schematic and tell you which wires to check.

That would be greatly appreciated. It's been a long road with this 750.
