P11Fe Fault Code: Understanding The Description And Troubleshooting Tips
The P11FE fault code refers to a problem with the O2 Low Reference Circuit High Voltage in NOx Sensor 2. This fault code is related to the Nitrogen Oxides (NOx) sensors, which are part of the selective catalytic reduction system in diesel engines.
There are two NOx sensors, one upstream and one downstream of the selective catalytic reduction system.
These sensors measure the concentration of NOx in the exhaust gas. The NOx sensors are connected to the Engine Control Module (ECM) via a CAN (Controller Area Network) and exchange information through it. The sensors are smart sensors, meaning that all the electrical monitoring is performed inside the sensor, and only the results are sent to the ECM. Each NOx sensor contains a sensing cell, a pumping cell, and a heater. The NOx sensor maintains a constant reference voltage across the sensing cell.
An electronic circuit within the sensor controls the pump current through the pumping cell to maintain this voltage.
The amount of current required to maintain the reference voltage is proportional to the concentration of NOx in the exhaust gas. 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 P11FE fault code.
This fault code indicates a problem with the O2 Low Reference Circuit High Voltage 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.
