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) Missing signal from NOx sensor (B96T) Probable cause1) Connector2) NOx sensor Volvo All Engines (2010 Emissions) Fault Code: SPN 3226 FMI 5 PID: PSID 90 Aftertreatment Outlet NOx Volvo All Engines (2010 Emissions) Fault Code: SPN 3226 FMI 31 PID: PSID 90 Aftertreatment Outlet NOx Volvo All...

This diagnostic function indicates malfunction at the exhaust gas temperature (EGT) sensor. The purpose of the exhaust gas sensor is to contribute the relevant temperatures required for the temperature regulated aftertreatment diesel particulate filter regeneration control. A faulty EGT sensor can result with a failed aftertreatment (DPF) regeneration. Conditions for diagnostic trouble code (DTC):1) Exhaust temperature, Lower than expected Observable symptoms1) This function indicates that the NOx conversion efficiency is not correct Probable cause1) Aftertreatment exhaust gas temperature (EGT) sensors installed in the incorrect location on the aftertreatment diesel particulate filter (DPF)2) Low compression3) Pre-catalyst, Exhaust Gas Temperature (EGT) Sensor4)...
