The sensor inside the driver's foot well at the base of the steering column and has FOUR wires:

They're connected to pins 1, 2, 5 & 6 on the sensor.

Pin 1 is GRY, and it will have a 5 VDC (4.9) reference signal from the EBCM.
It also feeds the YAW rate sensor and the lateral rate sensor.
I would also check for the voltage there. It is also a GRY wire.

Pin 2 is ORN/BLK, and it will have a LOW REF (sensor ground) Signal. It also goes to the YAW and lateral sensors as the same color wires.

Pin 5 is the Steering wheel position sensor signal phase A. It goes directly to the EBCM Lite green wire

Pin 6 is the Steering wheel position sensor signal phase B. It goes directly to the EBCM Lite Blue wire

If you disconnect the sensor plug, you should read (if I read the procedure correctly) .2 VDC on pin 5 & 6

Read the 5 VDC ref voltage to the Low ref pin 2, orange/blk wire should see 5 VDC.
If you measure the low ref pin to ground, it should not read any higher than 5 ohms.

I would hook up a jumper wire to pin #1 on the sensor and when the steering wheel is straight, you should see
The same output on pins 5 & 6. As you turn the wheel all the way right and left,
you should see one pin's voltage smoothly increase while the other one smoothly decreases.
