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.

How can I identify if the engine light is on due to fault code p11fc?

If your engine light is on and you suspect it’s due to fault code P11FC, there are a few things you can do to identify the issue. First, check for the symptom of the engine light being on or the service engine soon warning light. The most common cause of this fault code is a faulty Nitrogen Oxides (NOx) Sensor 2. It could also be due to an open or shorted harness or a poor electrical connection in the Nitrogen Oxides Sensor 2 circuit. To fix the issue, visually inspect the wiring harness and connectors, checking for any damage or corrosion. Also, look for any broken, bent, pushed out, or corroded pins in the connectors.

What are the possible causes of fault code p11fc?

If you’re seeing the engine light or service engine soon warning light on, the fault code P11FC could be the culprit. This code is often caused by a faulty Nitrogen Oxides (NOx) Sensor 2, an open or shorted harness, or a poor electrical connection in the NOx Sensor 2 circuit. To fix this issue, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded pins in the connectors.
