The P2552 automobile fault code indicates a problem with the Fuel Injector Control Module (FICM) or Powertrain Control Module (PCM). The most common symptom is the Engine Light ON or Service Engine Soon Warning Light. The cause of this fault code could be a faulty FICM or PCM, an open or shorted FICM harness, or a poor electrical connection in the FICM circuit.
The repair importance is high as it can lead to poor engine performance and fuel economy. The difficulty level of the repair is moderate, and it takes around 1.0 hour to fix. To interpret the fault code, check the possible causes listed above and visually inspect the related wiring harness and connectors for any damage or corrosion.
| Repair Importance Level | 10.0 (Out of 10) |
| Estimated Repair Time | Approximately 1.0 hour |
| Repair Difficulty Level | 6.67 (Out of 10) |
P2552: Unresponsive Fuel Cap – Symptoms & Solutions

P2552: Affordable Fix For Complex Automobile Fault Code
The automobile fault code P2552 can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the repair time, which is commonly charged between $75 and $150 per hour by most auto repair shops.
Therefore, the total cost of fixing the P2552 fault code will depend on the hourly rate charged by the repair shop and the estimated repair time required to fix the issue.
P2552: Fuel Pressure Sensor Circuit Low Input
The P2552 code refers to the ThrottleFuel Inhibit Circuit. It is related to the Diesel Engine Power Monitor (DEPM) strategy. The DEPM monitors the engine RPM when there is no power demand from the Accelerator Pedal Position (APP) sensor.
If the engine RPM does not exceed the DEPM limit, the DEPM disables the crankshaft and camshaft output signal sent to the PCM to the Fuel Injector Control Module (FICM).
FAQ
