If you see the engine light on or the service engine soon warning light, it could be due to the P1C54 fault code.
This code indicates a problem with the diesel exhaust fluid system, which could be caused by degraded, diluted, or incorrect fluid, deposits in the decomposition tube, exhaust leaks, or a malfunctioning dosing system or SCR catalyst. The importance of fixing this issue lies in the fact that it can lead to increased emissions and reduced fuel efficiency.
The repair difficulty is moderate, and it’s recommended to visually inspect the wiring harness and connectors for any damage or corrosion. The repair time is estimated at 1.0 hour.
To interpret the fault code, check the possible causes listed above and look for any damaged components or connector pins.
| Repair Importance Level | 10.0 (Out of 10) |
| Estimated Repair Time | Approximately 1.0 hour |

Crunching The Numbers: P1C54 Repair Cost & Complexity
The fault code P1C54 is a common issue in automobiles. The estimated repair time for this fault code is 1.0 hour.
The cost of fixing this fault code varies between $75 and $150 per hour, depending on the auto repair shop.
The cost may also vary based on the severity of the issue and the type of vehicle. It is important to get this fault code fixed as soon as possible to avoid any further damage to the vehicle.
P1C54: Understanding Your Car’s Battery Temperature Sensor Fault
The P1C54 code indicates that the SCR NOx Catalyst is missing. 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.
The NOx Sensors and NOx Sensor Modules are calibrated to each other and must be replaced as an assembly.
The NOx Sensor Modules perform their own internal diagnostics and report malfunctions back to the PCM. The PCM will illuminate the MIL lamp immediately after the monitor runs and fails. The PCM will turn off the MIL Lamp immediately after the monitor runs and passes.
FAQ
If you’re experiencing the P1C54 fault code, your engine light may be on. This could be due to a variety of causes, including degraded, diluted, or incorrect diesel exhaust fluid, diesel exhaust fluid deposit in the decomposition tube, exhaust leaks, malfunctioning diesel exhaust fluid dosing system, or malfunctioning SCR catalyst. To fix the issue, check the possible causes listed above and visually inspect the related wiring harness and connectors. Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
If you’re experiencing the P1C54 fault code, which is indicated by the engine light or service engine soon warning light being on, there are a few possible causes to consider. These include degraded, diluted, or incorrect diesel exhaust fluid, diesel exhaust fluid deposit in the decomposition tube, exhaust leaks, malfunctioning diesel exhaust fluid dosing system, and malfunctioning SCR catalyst. To fix the issue, start by visually inspecting the related wiring harness and connectors. Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
Ignoring the P1C54 fault code, which indicates a problem with the Diesel Exhaust Fluid system, can lead to serious consequences. The engine light will remain on, and the vehicle may go into a reduced power mode, causing poor performance and fuel economy. The cause of the fault could be degraded, diluted, or incorrect Diesel Exhaust Fluid, deposit in the decomposition tube, exhaust leaks, malfunctioning Diesel Exhaust Fluid Dosing System, or malfunction SCR Catalyst. It is essential to check the possible causes listed above and visually inspect the related wiring harness and connectors to avoid further damage.
Wrap Up
If your engine light is on, it could be due to degraded, diluted, or incorrect diesel exhaust fluid, diesel exhaust fluid deposit in the decomposition tube, exhaust leaks, malfunctioning diesel exhaust fluid dosing system, or malfunctioning SCR catalyst. Check the possible causes, inspect wiring harness and connectors, and look for damaged components or corroded pins.
