This trouble code indicates that the powertrain control module has detected a low reference voltage from the barometric pressure sensor.
Some of the potential causes of this trouble code would include:
Symptoms of this trouble code that the driver could potentially experience would include:
A mechanic may begin diagnosing this trouble code by first locating the barometric pressure sensor, the mass airflow sensor, and the throttle position sensor. Once the sensors have been located, the mechanic would then check the wiring and connectors for any obvious damage. Then the mechanic would test all of these sensors using the manufacturer's suggested procedures. If any codes related to the catalyst system or oxygen sensors were also stored, the mechanic would check for a clogged catalytic converter. If the cause of the issue is still not found after all of these tests are performed, the mechanic will then test the powertrain control module using the manufacturer's suggested procedure and relay all information over to the customer.
A common mistake that could be made when diagnosing this trouble code would be to replace the barometric pressure sensor without testing it first. Many times just because the code mentions a specific part a person may be led to believe that part is faulty. It is oftentimes the exact opposite.
This code is considered serious as it can cause driveability issues. Any trouble codes stored that can cause the engine to run poorly should be diagnosed and repaired as soon as possible in order to prevent further engine damage. It is also best to have the repairs performed by certified professional to ensure proper function of the engine afterwards.
Repairs that can potentially fix this trouble code would include:
It is not a good idea to drive on long trips with this code stored in your powertrain control module. These are the types of codes that can potentially lead to breakdowns and leave people stranded on the side of the road. As stated it is best to get something like this diagnosed and repaired as soon as possible in order to prevent further vehicle damage and the possibility of getting stranded.
