Easy Diagnosis of Engine Error OBD Code P081B

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


  • Diagnosing the P081B fault code can be easy; all you will need is 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 (TSB) 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 component testing procedures/specifications.
  • 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.
  • 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.
  • 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
