P081C - OBD Trouble Code

<<See All OBD Codes

The trouble code P081C can be defined as Park Input Circuit.

If you find out that the P081C trouble code is being stored, then it would mean that the fault in the PARK input circuit of the neutral safety switch by the powertrain control module.

It is always good to learn more! That is the reason why we are here to help you out in gaining more knowledge about the P081C error code. This trouble code is generic, which would mean that it can apply to all the vehicles which are equipped with the OBD-II or the vehicles which are made since 1996 up to the present. The specifications on the definition, the troubleshooting steps as well as repairs can always vary from one vehicle make to another.

This can happen because of a lot of reasons and the mechanic should diagnose the specific cause for this code.

What causes this problem with the Park Input Circuit?

• There can be distorted neutral safety or shift selector switch
• Some issues related to the shorted or open wiring or connectors in PARK input circuit
• Quirks in the PCM or a programming error

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

• You will need a diagnostic scanner, a digital volt/ohmmeter, and a source of vehicle specific diagnostic information to diagnose the P081C fault code.
• Inspect for technical service bulletins which pertain to the vehicle, symptoms, and codes. There can be some situations where this can save a lot of your precious time in the long run by pointing you in the correct way. A scanner can be used to retrieve all stored codes and pertinent freeze frame data. It is a good idea to write this information down before clearing the codes then test-drive the vehicle until the PCM either enters readiness mode or the code is reset.
• Now if the PCM would enter into the readiness mode at this time, the code is intermittent and may be much more difficult to diagnose. Now if you find out that this is the case, the state which contributed to the code being stored may need to worsen before an correct diagnosis can be made. If the code is reset immediately, the next step of your diagnosis will need that you search your vehicle information source for diagnostic flow-charts, connector pinout charts, connector face views, and constituent testing methods/specifications.
• You can use the DVOM to test PARK input voltage at the appropriate neutral position/shift selector switch. Typical PARK input circuits consist of either battery voltage when activated and on the other hand ground when deactivated. Use your source of vehicle diagnostic information and the DVOM to test neutral safety/shift selector switches as required. Replace switches that do not test within system parameters.
• If system switches and circuits are functional, use the DVOM to test PARK input circuits to the PCM. Disconnect all controllers prior to using the DVOM for testing. PARK input codes are most frequently attributed to neutral safety switch negligence.

Common Mistakes When Diagnosing The P081C Code

• Non performance of the neutral safety switch
• Failure in the powertrain control module
• Transmission control module might start failing
• There can be some issues related to the wiring
