Decoding Fault Code P11C8: Unveiling The Mystery Behind The Malfunction
The P11C8 fault code refers to a problem with the NOx Sensor 2 Heater Ground Circuit. This sensor is part of the selective catalytic reduction system, which helps reduce NOx emissions in diesel engines. There are two NOx sensors in this system, one upstream and one downstream of the selective catalytic reduction.
They are connected to the control module via CAN and exchange information through it. The NOx sensor contains a sensing cell, a pumping cell, and a heater.
The sensor measures the concentration of NOx in the exhaust gas by maintaining a constant voltage across the sensing cell.
The amount of current required to maintain this voltage is proportional to the NOx concentration.
In the case of the P11C8 fault code, the ECM has detected a high circuit ground condition in the NOx Sensor 2 Heater. This means that there is an issue with the electrical connection or the sensor’s heating element. When this fault code is triggered, the ECM sets a Diagnostic Trouble Code (DTC) to indicate the problem.
It is important to address this issue promptly to ensure proper functioning of the selective catalytic reduction system and reduce NOx emissions.
FAQ
If you’re seeing the engine light or service engine soon warning light and the fault code is p11c8, there are a few possible causes to consider. One is a faulty Nitrogen Oxides (NOx) Sensor 2. Another possibility is that the Nitrogen Oxides Sensor 2 harness is open or shorted, or there may be a poor electrical connection in the circuit.
