P116B Fault Code: Understanding The Causes And Solutions
The P116B fault code refers to the O2 signal circuit having a low voltage in NOx Sensor 1. 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 are connected to the control module via CAN and exchange information through it. The NOx sensors have a sensing cell, a pumping cell, and a heater.
The sensors maintain a constant reference voltage across the sensing cell and control the pump current through the pumping cell. The amount of current required is proportional to the concentration of NOx in the exhaust. The ECM adjusts the amount of diesel exhaust fluid based on the NOx levels.
The P116B code is set when a fault or performance issue is detected in the NOx sensor circuitry or sensor for more than 2 seconds.
FAQ
If you see the engine light or service engine soon warning light on, the fault code P116B could be the culprit.
