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

A suitable OBD-II scanner (or code reader) and a digital volt/ohmmeter will be most helpful in performing a successful diagnosis. The trouble code can be viewed by the mechanic and can see when the P0871 code was actually stored. After that the technician should reset the trouble code and then the vehicle should be taken out for a test drive.

Now if the code is appearing again and again when the test drive is being done, then it means that there is surely some fault in the transmission fluid pressure. Then a multimeter should be used to test the wiring as well as the factory test points which can be damaged. Then the mechanic should test the wiring around the transmission sensor circuitry to see if it is defective or corroded. The transmission should also be inspected to see if there is any leakage in the fluid.

Common Mistakes When Diagnosing The P0871 Code

• There can be a lot of issues which might appear when the P0871 error code start flashing up.
• Many a times the mechanic might not react properly and would just replace the fluid when in reality the transmission should be restored so that it can work properly.
• There are some cases where the transmission would be correct and on the other hand there can be less fluid.
• If there is an excessive heating of the transmission, then it that case the transmission should be taken out completely. Just keep in mind that this might not be always required.
