The P2553 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 p2553 fault code.

Here are the symptoms to look out for:

  • The P2553 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 hesitation during operation, 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 P2553 can be caused by a faulty FICM, PCM, open harness, or poor electrical connection.

  • The automobile fault code P2553 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 p2553, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code P2553, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors for any damage.
  • Look 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 P2553 is related to the engine oil pressure sensor circuit.

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 location of the shop, the type of vehicle, and the severity of the issue.

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

The P2553 code is related to the Diesel Engine Power Monitor (DEPM) strategy. It 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). The P2553 code indicates a problem with the ThrottleFuel Inhibit Circuit RangePerformance.

What are the possible causes of the P2553 automobile fault code?

If you’re experiencing the P2553 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 damaged components or corroded connector pins.

How can I visually inspect the related wiring harness and connectors to fix the P2553 fault code?

If you’re experiencing the P2553 fault code, which is indicated by the engine light or service engine soon warning light being on, there are a few possible causes. These include 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, you should visually inspect 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 P2553 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 P2553 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.
