P081A OBD Error Code: Problem & Solutions

<<See All OBD Codes

The trouble code P081A can be explained as Starter Disable Circuit Low. If the P081A trouble code is appearing, then it would mean that the powertrain control module has detected a degree of voltage that is higher than expected in the starter disable switch circuit.

Do you want to know more about the P081A fault code? Don’t worry! Parts Avatar Canada is here at your service. The starter disable circuit signal is monitored by the transmission control module. The P081A error code would start triggering up when the starter disable circuit signal would not be as per the parameters set by the manufacturer.

What causes this problem with the Starter Disable Circuit Low?

• Malfunctioning starter disable switch
• The wiring or connectors in starter disable switch circuit might be shorted or opened up
• Imperfect PCM or a programming error

1. Starter Relay - A faulty Starter Relay can be troublesome. You can always rely on us as we have best auto parts for our customers.
2. Auto Transmission Control Module - If everything is alright with PCM, then there is surely some defect in Auto Transmission Control Module. Get it replaced before the situation gets worse.
3. Body Control Module Component - P081A code can display due to some defaults in the Body Control Module Component. So, it is very important to replace the Body Control Module Component with us at equitable prices.
4. Powertrain Control Module - Do you remember when was the last time you got your car Powertrain Control Module checked up? A dirty Powertrain Control Module can cause a lot of issues like displaying P081A code.
5. Engine Control Module - Are there some faults in your Engine Control Module? Don’t waste time and get them replaced or else P081A code can turn up.

There could be countless symptoms which that would accompany with this fault code. Willing to know some common symptoms of OBD Trouble Code P081A? Your wish is our demand. Have a look at them below:

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P081A code to be stored:

If you are willing to diagnose the P081A trouble code, then you will require a diagnostic scanner, a digital volt/ohmmeter, and a source of vehicle specific diagnostic information. You may use your source of vehicle information to locate a technical service bulletin that matches the vehicle year, make, and model; as well as the engine size, code/s stored, and symptoms exhibited. If you find one, it could yield helpful diagnostic information. You can always use the scanner to retrieve all stored codes and pertinent freeze frame data. It would be a great idea to write this information down before clearing the codes then the vehicle should be taken out for a test drive until the PCM either enters readiness mode or the code is reset. Now if the PCM would enter readiness mode at this time, the code is intermittent and may be much more difficult to diagnose. If this is the case, the conditions which contributed to the code being stored may need to worsen before an accurate diagnosis can be made. If the code is immediately reset, the next step of your diagnosis will require that you search your vehicle information source for diagnostic flow-charts, connector pinout charts, connector face views, and constituent testing specifications as well as methods.

Here is the Step 1

You should utilize the DVOM to test voltage, ground, and signal output at the appropriate starter disable switch. Typical starter disables switch circuits consist of either battery voltage when activated or on the other hand ground when deactivated.

Here is the Step 2

A source of vehicle diagnostic information should be used and the DVOM to test starter disable switches as per the need. The switches which do not test within system parameters should be replaced properly.

Here is the Step 3

If system switches and circuits are functioning, then use the DVOM to test starter disable switch circuits to the starter, as well as to the PCM. All the controllers prior to using the DVOM for testing should be disconnected.

• Starter disable switch circuit codes are most frequently assigned to switch failure
• Automobiles with manual transmissions often use a number of starters disable switches
