If you want to easily diagnose this fault code, then all you have to do is to follow the steps which are mentioned below:

An OBD-II scanner should be connected to the automobiles OBD-II port by the technician. It is generally situated below the dash on the driver side of the car, and is scaled overhead the brake and gas pedals.

There are some automobiles which have the port mounted on the passenger side below the dash. The code should be cleared up from the car’s computer by the mechanic and then the vehicle should be taken out for a test drive to check that the situation repeats. Then the code should be reset.

Now when the test drive is being done, the live data from the vehicle’s computer should be viewed by the mechanic to guard the right functioning values. If the code is reset, the mechanic should then visually check the select stroke sensor and sensor circuit.

Proper checking as well as diagnostics should be performed on the transmission control module. There can be some signs of faults like the wiring might be defective. If you do not notice any visual defect, then further diagnostics would be carried out by the mechanic utilizing a digital voltmeter.
