If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p1c55 fault code.

Here are the symptoms to look out for:

  • The P1C55 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 reduced engine power, decreased fuel efficiency, rough idling, stalling, and difficulty starting the engine.
  • Additionally, the vehicle may experience transmission shifting problems, and the speedometer may not function correctly.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

P1C55 fault code can be caused by various issues such as exhaust leaks, engine misfire, and faulty NOX sensor.

  • The automobile fault code P1C55 can be caused by several factors.
  • These include exhaust leaks, engine misfire, excessive oil consumption, EGR system leak, faulty NOX sensor bank 1 sensor 1, NOX sensor bank 1 sensor 1 harness being open or shorted, and poor electrical connection in the NOX sensor bank 1 sensor 1 circuit.
  • It is important to identify the specific cause of the fault code to ensure proper diagnosis and repair.

Below are the possible fixes for the automobile fault code p1c55, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code P1C55, 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 fault code P1C55 is a diagnostic trouble code related to the hybrid battery pack.

The estimated repair time for this fault code is 1.0 hour. The cost of fixing this fault code is influenced by the hourly rate charged by the auto repair shop, which is typically between $75 and $150 per hour. Other factors that may affect the cost of fixing this fault code include the severity of the issue, the type of vehicle, and the availability of replacement parts.

The P1C55 fault code indicates an intermittent issue with the NOx Sensor on Bank 1. The aftertreatment system has two NOx Sensors and modules that are calibrated to each other. The NOx Sensors monitor the efficiency of the SCR Catalyst and dosing system and communicate with the PCM over the J1939 Data Link.

The PCM will illuminate the MIL after the diagnostic runs and fails in two consecutive drive cycles, and turn it off immediately after the monitor runs and passes. The NOx Sensor and Module assemblies must be replaced together and are not interchangeable. The NOx Sensor Modules perform their own internal diagnostics and report malfunctions back to the PCM.

What are the possible causes of the P1C55 fault code in an automobile?

If you see the engine light on or service engine soon warning light in your automobile, it could be due to the P1C55 fault code. This code can be caused by various factors such as exhaust leaks, engine misfire, excessive oil consumption, EGR system leak, faulty NOX sensor bank 1 sensor 1, NOX sensor bank 1 sensor 1 harness is open or shorted, or NOX sensor bank 1 sensor 1 circuit poor electrical connection. To fix this issue, you should check the possible causes listed above and visually inspect the related wiring harness and connectors. Also, check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.

How can one visually inspect the wiring harness and connectors related to the P1C55 fault code?

If you’re experiencing an Engine Light ON or Service Engine Soon Warning Light due to the P1C55 fault code, 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 also check for exhaust leaks, engine misfire, excessive oil consumption, EGR system leak, faulty NOX Sensor Bank 1 Sensor 1, and poor electrical connection in the NOX Sensor Bank 1 Sensor 1 circuit.

What are the consequences of ignoring the P1C55 fault code in an automobile?

Ignoring the P1C55 fault code in an automobile can lead to serious consequences. The engine light will remain on, indicating a problem with the NOX Sensor Bank 1 Sensor 1, which can result in engine misfires, excessive oil consumption, and exhaust leaks. It is important to visually inspect the related wiring harness and connectors, and check for damaged components to avoid further damage.
