Crank position sensor

Hello everyone. I was wondering if any one else is having the issue I am having. I am getting codes for the crank position sensor and I believe its not getting enough volts. I tested the wires and I'm getting 5 volts from 2 of the wires and I assume the 3rd is the signal wire. The only thing I can think of is one if the control modules are bad or their is a short.

IF all of the wires and connectors are good the sensor must be bad.
P0365 is NOT the crankshaft sensor it IS the exhaust camshaft sensor. Likewise a wire/connector/sensor problem.
Here are the testing procedures:

Do you by chance know what each wire is by cable color. I was getting 5 volts between two of the wires and nothing on the 3rd. If I'm understanding the procedure correctly I probly should replace the ecm

It is rarely the ECM that’s the problem

I do notice to inspect the timing chain and oil debris in the P0335 description, a loose chain will through off the cam and crankshaft position correlations

How many miles since last timing chain and tensioner?
