Volvo All Engines (2010 Emissions) Fault Code: SPN 3226 FMI 3 PID: PSID 90 Aftertreatment Outlet NOx

Category All Engines (2010 Emissions) Tags 2010, 3, 3226, 90, Aftertreatment, All, CodeSPN, Emissions, Engines, Fault, FMI, NOx, Outlet, PIDPSID, Volvo

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) Voltage above normal or shorted high

Observable symptoms
1) None

Probable cause
1) Internal fault in component
