[SOLVED] P2555 Code: High Throttle/Fuel Inhibit Circuit – Quick Fix Guide

The P2555 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 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 p2555 fault code. Here are the symptoms to look out for:

  • The P2555 fault code in automobiles can cause several symptoms, including the engine light turning on or the service engine soon warning light appearing.
  • Other symptoms may include a decrease in engine power, difficulty starting the engine, and poor acceleration.
  • Additionally, the vehicle may experience stalling or misfiring, and the transmission may shift roughly or erratically.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

The automobile fault code P2555 can be caused by a faulty FICM, PCM, open harness, or poor electrical connection.

  • The automobile fault code P2555 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 p2555, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code P2555, 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 P2555 is related to the throttle or accelerator pedal position sensor. The estimated repair time for this issue 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.

It is important to address this issue promptly to avoid further damage to the vehicle.

The P2555 code is related to the Diesel Engine Power Monitor (DEPM) strategy. It indicates that the ThrottleFuel Inhibit Circuit is reading a high voltage signal. This means that the DEPM has disabled the crankshaft and camshaft output signal to the Fuel Injector Control Module (FICM).

This can cause a lack of power and acceleration in the vehicle.

It is important to have this issue diagnosed and repaired by a qualified mechanic to avoid further damage to the engine.

What are the possible causes of the P2555 automobile fault code?

If you’re experiencing the P2555 fault code, you may notice that your engine light is 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, it’s important to visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s 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. This will help you identify any open or shorted circuits and ensure a proper electrical connection.

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 or replacing the connector, reconnect the battery and clear the codes. Finally, start the engine and check if the engine light is still on.
