When discussing the FIAT Code P1CEA, it is essential to understand the Powertrain Control Module (PCM) and the problems associated with the boost side EVAP purge system performance. The FIAT Code P1CEA is a diagnostic trouble code (DTC) that indicates an insufficient vapor flow in the evaporative system operation during a boost condition. This code can be caused by a variety of issues, such as excessive resistance in FTP sensor circuits, blockage or flash in the CAC duct or air cleaner, evaporative purge hose/tube and air filter obstruction, OBD vent valve or ejector tee malfunction, fuel tank pressure sensor, or purge solenoid vacuum supply. To diagnose and resolve these issues, reviewing the related service bulletins is essential.

| Excessive Resistance in FTP Sensor 5-Volt Supply Circuit | Check the wiring in the FTP Sensor 5-Volt Supply Circuit for any signs of damage and replace any damaged components. |
| Excessive Resistance in FTP Sensor Signal Circuit | Diagnose the FTP Sensor Signal Circuit for any issues and replace faulty components. |
| Excessive Resistance in FTP Sensor Return Circuit | Inspect the FTP Sensor Return Circuit for any signs of damage and replace any faulty components. |
| Blockage/Flash at the Ports on the CAC Duct and the Air Cleaner | Clean the CAC Duct and the Air Cleaner ports to remove any blockages or flash. |
Excessive Resistance in FTP Sensor 5-Volt Supply Circuit
When diagnosing issues related to the FIAT Code P1CEA, it is essential to check the wiring in the FTP Sensor 5-Volt Supply Circuit for any signs of damage or corrosion. If any damage is present, the components must be replaced before further diagnosis can occur.
Excessive Resistance in FTP Sensor Signal Circuit
When troubleshooting the FIAT Code P1CEA, it is essential to diagnose the FTP Sensor Signal Circuit for any issues causing the code to be present. Replacement of any components that are found to be faulty will be necessary to resolve the issue.
Excessive Resistance in FTP Sensor Return Circuit
Inspecting the FTP Sensor Return Circuit is necessary when troubleshooting the FIAT Code P1CEA. Any signs of damage or corrosion must be identified, and any faulty components must be replaced to resolve the issue.
Blockage/Flash at the Ports on the CAC Duct and the Air Cleaner
The FIAT Code P1CEA can also be caused by blockages or flash at the ports on the CAC Duct and the Air Cleaner. To resolve the issue, these ports must be cleaned to remove any blockages or flashes.
Conclusion
The FIAT Code P1CEA is a diagnostic trouble code (DTC) that causes a variety of issues, such as excessive resistance in FTP sensor circuits, blockage or flash in the CAC duct or air cleaner, and evaporative purge hose/tube and air filter obstruction, among others can cause. It is essential to inspect the wiring, diagnose any issues with the FTP sensor circuits, and clean any blockages or flash in the CAC duct or air cleaner to diagnose and resolve the issue. The FIAT Code P1CEA can be determined by following the service bulletins and instructions outlined in the article.
