Decoding Fault Code P11C7: Unveiling The Mystery Behind The Malfunction
The P11C7 fault code refers to a problem with the ground circuit of the NOx Sensor 2 Heater.
The NOx sensors are part of the selective catalytic reduction system, which reduces NOx emissions in diesel engines.
There are two NOx sensors, one upstream and one downstream of the selective catalytic reduction system. The sensors are connected to the control module via CAN and exchange information through it. The NOx sensors are smart sensors, with electrical monitoring performed inside the sensor.
The sensors contain a sensing cell, a pumping cell, and a heater. The NOx sensor maintains a constant reference voltage across the sensing cell.
The ECM varies the amount of diesel exhaust fluid added based on the NOx levels detected by the sensors. The P11C7 fault code is set when a fault in the NOx sensor circuitry or a performance fault in the sensor is detected for more than 2 seconds. In this case, the fault is specifically related to the ground circuit of NOx Sensor 2 Heater.
FAQ
If you’re seeing the engine light or service engine soon warning light, the fault code P11C7 could be caused by a faulty Nitrogen Oxides (NOx) Sensor 2, an open or shorted harness for the sensor, or a poor electrical connection in the sensor circuit.
