Having a FIAT P1185 Code can be a nightmare for car owners. The code, which stands for general pressure sensor correlation, is a diagnostic trouble code that indicates that the powertrain control module (PCM) is not receiving signals from two of the three sensors it monitors: the boost pressure sensor, MAP sensor, and BARO sensor. The two sensors that are within a specific range of each other and the third one that is not will be declared irrational by the PCM. In this case, the cause of the FIAT P1185 Code can be traced back to the boost pressure sensor, MAP sensor, wiring, connectors, or the powertrain control module (PCM) itself. This article will discuss possible causes and solutions to the FIAT P1185 Code.
Causes and Solutions for FIAT P1185 Code
| Cause | Solution |
|---|---|
| Boost pressure sensor, wiring, or connectors | Ensure all wiring and connectors are in good condition and replace any faulty components. |
| MAP sensor, wiring, or connectors | Check the MAP sensor, wiring, and connectors for any damage or corrosion and make the necessary repairs or replacements. |
| Powertrain control module (PCM) | Replace the PCM if necessary. |
| Related service bulletins | Review service bulletins to check for any known issues. |
Having a FIAT P1185 Code can be a frustrating experience, but with the right knowledge, it can be solved quickly and easily. By understanding the causes and solutions of this code, car owners can quickly identify the issue and take the necessary steps to resolve it. The most common causes are the boost pressure sensor, MAP sensor, wiring, connectors, and powertrain control module (PCM), but there may be other causes as well. As such, it is important to review service bulletins to check for any known issues. With the right knowledge, car owners can take the proper steps to solve the issue and get their vehicle running smoothly again.
Boost Pressure Sensor, Wiring, and Connectors
The boost pressure sensor, wiring, and connectors are all essential components for the proper operation of the FIAT P1185 Code. To ensure that these parts are in good condition, car owners should inspect them for any signs of damage or corrosion. If any of these components are not in good condition, they should be replaced to ensure that the code is resolved.
MAP Sensor, Wiring, and Connectors
The MAP sensor, wiring, and connectors are all important components for the proper operation of the FIAT P1185 Code. If any of these components are damaged or corroded, the code may not be resolved. To check these components, car owners should inspect them for any signs of damage or corrosion. If any of the components are not in good condition, they should be replaced to ensure that the code is resolved.
Powertrain Control Module (PCM)
The powertrain control module (PCM) is the component that is responsible for controlling the FIAT P1185 Code. If the PCM is damaged or not functioning properly, the code may not be resolved. To check the PCM, car owners should inspect it for any signs of damage or corrosion. If the PCM is not in good condition, it should be replaced to ensure that the code is resolved.
Service bulletins are an important source of information when diagnosing and resolving the FIAT P1185 Code. These bulletins provide detailed information about known issues and solutions. By reviewing service bulletins, car owners can quickly identify any known issues and take the necessary steps to resolve them.
Conclusion
Having a FIAT P1185 Code can be a daunting task for car owners, but with the right knowledge, it can be solved quickly and easily. By understanding the causes and solutions of this code, car owners can quickly identify the issue and take the necessary steps to resolve it. The most common causes are the boost pressure sensor, MAP sensor, wiring, connectors, and powertrain control module (PCM). Additionally, car owners should review service bulletins to check for any known issues. With the right knowledge and resources, car owners can take the proper steps to solve the issue and get their vehicle running smoothly again.
