Volvo All Engines (2010 Emissions) Fault Code: SPN 4334 FMI 2 PID: PPID 273 Aftertreatment 1 SCR Dosing Reagent Absolute Pressure
The aftertreatment control module (ACM) uses the aftertreatment diesel exhaust fluid (DEF) dosing pressure sensor value to adjust and maintain DEF pressure at the DEF dosing valve by controlling DEF pump speed. If the pressure decreases below expected value when the pump is in initial pressure build-up mode or if the pressure increases above expected value when pump is in idle speed mode, the ACM considers DEF pressure outside of normal operating range and indicates a malfunction in a DEF dosing pressure sensor.
Conditions for diagnostic trouble code (DTC):
1) Abnormal value
Probable cause
1) Hose
2) Pressure sensor
3) Aftertreatment diesel exhaust fluid (DEF) pump, Internal fault
