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

• All the existing trouble codes as well as freeze frame data should be recorded. This information can prove to be extremely useful in diagnosing the intermittent error.
• If you find out that there are some additional codes as well, and then keep in mind to note down the exact order in which they are stored and then resolve them. If you will not be able to do this properly, then it would result in the misdiagnosis as well as not needed replacement of the constituents.
• You can easily find the gear shift mechanism by referring to the manual. Carefully check all the associated parts for signs of damage, water intrusion as well as other defaults. All the electrical connectors should be checked properly. The connectors which are defective should be replaced.
• If you find out that any part which is related with the gear selector mechanism is faulty, then you should restore the parts.
• Monitor the entire related wiring look for faulty burnt, shorted, disconnected, or corroded wiring as well as connectors. Restore the wiring or make repairs as per the requirement.
• If there is no fault in the wiring or any constituents is found, prepare to execute continuity, resistance, ground integrity, and where applicable, reference voltages tests on all related wiring, but be sure to disconnect all wiring from the PCM to prevent damaging the controller during resistance tests.
• If all electrical values check out, the scanner should be utilized to activate all actuators a number of times to rule out intermittent issues. Inspect the status of each actuator as it is activated, and restore those that are slow to react, or do not react at all.
• All the codes should be cleared up once all the restoration is fully completed. Run the automobile properly for at least one complete drive cycle to see if the code returns.
• If you find out that the codes is still returning, then doubt an intermittent fault, or flawed PCM. You must repeat all the electrical tests properly unless and until the issue is found as well as mended properly.
