The P2554 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 issue 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, one needs to 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 p2554 fault code. Here are the symptoms to look out for:

  • The P2554 fault code in an automobile can cause several symptoms, including the engine light turning on or the service engine soon warning light appearing.
  • Other symptoms may include issues with the vehicle’s transmission, such as difficulty shifting gears or the transmission slipping.
  • The vehicle may also experience a decrease in power or acceleration, and the engine may stall or hesitate during operation.
  • Additionally, the vehicle’s fuel efficiency may decrease, and there may be a noticeable decrease in overall performance.

The automobile fault code P2554 can be caused by various factors, including a faulty FICM or PCM, open or shorted harness, and poor electrical connection.

  • The automobile fault code P2554 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 the possible fixes for the automobile fault code p2554, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code P2554, 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 P2554 indicates an issue with the vehicle’s fuel pressure sensor circuit. The estimated repair time for this fault code is 1.0 hour. The cost of fixing this issue can vary depending on the auto repair shop, but it is common for most shops to charge between $75 and $150 per hour.

Other factors that may influence the cost include the severity of the issue, the type of vehicle, and the location of the repair shop.

The P2554 code is related to the Diesel Engine Power Monitor (DEPM) strategy. It indicates that the ThrottleFuel Inhibit Circuit is low.

The DEPM monitors the engine RPM when there is no power demand from the Accelerator Pedal Position (APP) sensor. Under normal engine idle operation, the DEPM RPM value must always be higher than the engine RPM.

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 P2554 automobile fault code?

If you’re experiencing the P2554 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 the issue, check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for damaged components or corroded connector pins.

How can I visually inspect the wiring harness and connectors related to the Fuel Injector Control Module?

If your engine light is on due to a faulty Fuel Injector Control Module (FICM), Powertrain Control Module (PCM), or poor electrical connection, you can visually inspect the related wiring harness and connectors to fix the issue. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. Make sure to check the “Possible Causes” listed above before proceeding with the inspection.

What are the steps to take if I find broken, bent, pushed out, or corroded connector’s pins while inspecting the wiring harness and connectors?

If you find broken, bent, pushed out, or corroded connector’s pins while inspecting the wiring harness and connectors, follow these steps. First, disconnect the battery to avoid any electrical shock. Then, use a magnifying glass to inspect the pins closely. If you find any damage, replace the connector or repair the pins. After repairing, reconnect the battery and clear the codes. Finally, start the engine and check if the engine light is still on.
