The NOx sensor measures the amount of NOx in the exhaust system. The NOx sensor is connected in the J1939-2 data link. This diagnostic trouble code (DTC) indicates a NOx monitoring failure. For example; NOx sensor short- or open circuit, NOx sensor removed, NOx sensor missing signal.
Conditions for diagnostic trouble code (DTC):
1) Internal NOx sensor heating failure
Observable symptoms
1) NOx value not readable with Tech tool
Probable cause
1) Software
2) Internal fault in component
