The P1C55 fault code in automobiles is a generic powertrain code that indicates a problem with the NOX (Nitrogen Oxide) sensor circuit in Bank 1 Sensor 1. The most common symptom of this fault is the illumination of the Engine Light or Service Engine Soon Warning Light. The possible causes of this fault include exhaust leaks, engine misfire, excessive oil consumption, EGR system leak, faulty NOX sensor, and poor electrical connection.

The repair importance of this fault is high as it can lead to increased emissions and reduced fuel efficiency. The repair difficulty is moderate, and the fix involves visually inspecting the wiring harness and connectors, checking for damaged components, and looking for broken, bent, pushed out, or corroded connector’s pins. The repair time for this fault is estimated to be around 1.0 hour.

It is essential to interpret the fault code correctly to identify the root cause of the problem and fix it effectively.

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. The upstream NOx Sensor 11 is located on the Turbocharger elbow downpipe and is permanently connected to a corresponding Nox Sensor Module mounted to the hot side of the engine block.

The downstream NOx Sensor 12 is located at the outlet of the SCR Catalyst and is permanently connected to a corresponding Nox Sensor Module which is mounted on the right frame rail.

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.
