P11Fc Fault Code: Understanding The Description And Troubleshooting Tips
The P11FC fault code refers to a problem with the O2 Low Reference Circuit in NOx Sensor 2. 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 placed 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.
It measures the concentration of NOx in the exhaust gas by maintaining a constant reference voltage across the sensing cell.
The amount of current required to maintain this voltage is proportional to the NOx concentration. If the ECM software detects a fault in the NOx sensor circuitry or a performance fault in the NOx sensor for more than 2 seconds, it will set the P11FC fault code. This indicates a problem with the O2 Low Reference Circuit in NOx Sensor 2.
It is important to address this issue promptly to ensure proper functioning of the selective catalytic reduction system and reduce NOx emissions from the engine.
