Here are some steps which you should follow in order to diagnose this fault code:

The P0827 error code can be diagnosed by utilizing an OBD-II trouble code scanner. A scanner should be used by a professional technician to notice the freeze frame data, to assemble details about the code. The mechanic can also check to see if there is presence of additional trouble codes. Now if there are a number of codes, then they should be addressed in the same order in which they are appearing on the scanner. After that the mechanic should reset the trouble codes, restart the vehicle, and check to see if the code remains detected. If it does not, then the code was likely triggered incorrectly, or represents an intermittent issue.

Now if you find out that the P0827 error code remains detected, then the technician should undergo a visual inspection of the electrical components in the automatic transmission. You should restore any open or shorted wires, or defective or corroded connectors. Then examine the upshift/downshift switch and you can always replace it if it is faulty.

If you are still not able to find the issue, then you should inspect the reference voltage and ground signals, and a digital volt/ohmmeter can be utilized to test for resistance and continuity between all the circuits.

Once any constituent is being replaced, then the trouble codes should be retested by the technician. Then restart the vehicle, and once again inspect to see if the codes return. This is done so that the mechanic would be able to find out that the issue has been solved.
