In step 2 it states your checking voltage so DC voltage is what the meter is set to. The sensor is where the shift linkage connects to the transmission.
Sure we can work through the results you get from the diag steps if your not able to follow those steps based on the results you get.
Since your not able to do the test it may be best to just replace the sensor to rule that out.
Hello again Chris here,
