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 Level10.0 (Out of 10)
Estimated Repair TimeApproximately 1.0 hour
Repair Difficulty Level6.67 (Out of 10)

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p2552 fault code. Here are the symptoms to look out for:

  • The P2552 fault code in an automobile can cause several symptoms.
  • The most common symptom is the illumination of the engine light or service engine soon warning light.
  • Other symptoms include a decrease in engine power, difficulty in starting the engine, and poor acceleration.
  • The vehicle may also experience stalling or misfiring, and the transmission may shift roughly or erratically.
  • Additionally, the vehicle may experience reduced fuel efficiency and emit excessive exhaust emissions.
  • If you notice any of these symptoms, it is important to have your vehicle diagnosed and repaired by a qualified mechanic.

The automobile fault code P2552 can be caused by a faulty FICM, PCM, open harness, or poor electrical connection.

  • The automobile fault code P2552 can be caused by a faulty Fuel Injector Control Module (FICM).
  • It can also be caused by a faulty Powertrain Control Module (PCM).
  • Another cause of this fault code is when the Fuel Injector Control Module harness is open or shorted.
  • Lastly, a poor electrical connection in the Fuel Injector Control Module circuit can also trigger this fault code.

Below are some possible fixes for the automobile fault code p2552, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code P2552, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

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.

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).

What are the possible causes of the P2552 automobile fault code?

If you’re experiencing the P2552 fault code, your engine light may be on. This could be due to a faulty Fuel Injector Control Module (FICM), a faulty Powertrain Control Module (PCM), an open or shorted Fuel Injector Control Module harness, or a poor electrical connection in the Fuel Injector Control Module circuit. To fix this issue, check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for any damaged components or broken, bent, pushed out, or corroded connector pins.

How can I visually inspect the related wiring harness and connectors to fix the P2552 fault code?

If you’re experiencing an Engine Light ON or Service Engine Soon Warning Light due to a P2552 fault code, there are a few possible causes to consider. These include a faulty Fuel Injector Control Module (FICM), Powertrain Control Module (PCM), or a poor electrical connection in the Fuel Injector Control Module circuit. To fix the issue, start by visually inspecting the related wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins.

What are the signs of a faulty Fuel Injector Control Module (FICM) that may cause the P2552 fault code?

If you notice the engine light or service engine soon warning light on, it could be a sign of a faulty Fuel Injector Control Module (FICM) causing the P2552 fault code. Other possible causes include a faulty Powertrain Control Module (PCM), an open or shorted Fuel Injector Control Module harness, or poor electrical connection in the Fuel Injector Control Module circuit. To fix the issue, visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
