The automobile fault code P11BF indicates a problem with the Nitrogen Oxides (NOx) Sensor 2.
The most common symptom is the Engine Light being ON or the Service Engine Soon Warning Light.
The cause of this fault code can be a faulty NOx Sensor 2, an open or shorted harness, or a poor electrical connection in the circuit. To fix this issue, you should visually inspect the wiring harness and connectors for any damage. Look for broken, bent, pushed out, or corroded pins in the connectors.
The repair time for this problem is estimated to be around 1.0 hour.
It is important to address this issue promptly to ensure proper functioning of the vehicle.

P11Bf Fault Code: Understanding The Description And Troubleshooting Steps
The P11BF fault code refers to a low voltage condition in the O2 reference voltage circuit of NOx Sensor 2. NOx sensors are part of the selective catalytic reduction system used to reduce NOx emissions 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 smart sensors that perform electrical monitoring inside the sensor and send the results to the Engine Control Module (ECM). Each sensor contains a sensing cell, a pumping cell, and a heater. The sensing cell maintains a constant reference voltage, and the pumping cell controls the pump current to maintain this voltage.
The amount of current required is proportional to the concentration of NOx in the exhaust. In the case of the P11BF fault code, the ECM has detected a low voltage condition in the O2 reference voltage circuit of NOx Sensor 2. This could be due to a fault in the sensor circuitry or a performance issue with the sensor itself. The ECM sets a Diagnostic Trouble Code (DTC) when it receives a message from the NOx sensor module indicating this condition.
The DTC will be set if the fault persists for more than 2 seconds. If you encounter the P11BF fault code, it is important to have the NOx sensor system inspected and repaired by a qualified technician.
They will be able to diagnose the exact cause of the fault and take the necessary steps to fix it.
Ignoring this fault code could lead to increased NOx emissions and potential damage to the engine.
FAQ
