<<See All OBD Codes

You’ve found out that the P0931 code is set, and you don’t know what that means. Well, don’t worry this OBD code falls under the generic category, and can be resolved with the right information and by following the diagnostic steps. The P0931 error is related to a voltage reading issue with the gear shift lock solenoid circuit. The Powertrain Control Module or PCM detects the voltage reading from the gear shift lock solenoid, if it finds that it’s unusually high then it will proceed to set the error code and the check engine light will go on.

In every vehicle It is the job of the transmission to convert the power produced by the engine for movement of the vehicle as commanded by the driver. The control module of the transmission is the Transmission Control Module. The Transmission Control Module will use solenoids to control the fluid pressure. These solenoids help in activating the different gears inside the transmission. If there’s an unreasonable signal sent from the shift solenoid, it will set P0931 code.

What causes this problem with the Gear Shift Lock Solenoid Circuit High?

• Defect in the gear shift lock solenoid
• Defect found in the brake light switch
• Voltage of the battery is low Malfunction of the PCM
• Damages of the circuit, wire and connectors

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P0931 code to be stored:

This OBD code P0931 can be diagnosed using the trouble code scanner. Retrieve all the codes and free frame data and try to gather as much information about the code and note if any other trouble codes are present. If there are multiple codes set, then they should be dealt with in the order of their appearance. Then clear all the trouble codes and restart the vehicle and see if the code is reset of if the PCM enters readiness mode. If the latter happens then it’s a sign that either the code was triggered wrongly or an intermittent error is present, in such a case it may require the problem to worsen before correct diagnosis can be made.

If the code is reset, then start a visual inspection of all the electrical components. Observe for any loose, or corroded connectors, there may also be open or shorted wired, all of these damages will need to be repaired or replaced as required. Make sure you also check the battery and see if it’s properly charged. The next in line for inspection is the gear shift lock solenoid, test it for continuity. This is usually the reason for the P0931 code. If you find that the solenoid is in good condition then you will have to check the brake light switch. Once you have made all the repairs and replacements, pause the inspection and reset the codes to see if it returns upon test drive. This step is very important for the mechanic to know if the error of the P0931 code is resolved or not.

Common Mistakes When Diagnosing the P0931 Code

There are some mistake commonly made during the diagnostic process such as:

• Not following the diagnosis protocol accurately. This can help is avoiding unnecessary repairs
