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

Volvo All Engines (2010 Emissions) Fault Code: SPN 4354 FMI 3 PID: PSID 103 Aftertreatment Diesel Exhaust Fluid (DEF) Line Heater 1

This diagnostic trouble code (DTC) indicates a malfunction at the diesel exhaust fluid (DEF) line heater 1. The DEF line and line connection between the DEF tank and DEF dosing valve is electrically heated by the DEF line heater 1. The DEF line heater 1 is normally OFF and is commended ON by the aftertreatment control module (ACM) when the ambient air temperature (AAT) and DEF tank temperature are below calibrated threshold. The ACM controls the DEF heater 1 by supplying battery voltage to the common voltage supply circuit and grounding control wire (-) circuit using pulse width modulated signal.

Conditions for diagnostic trouble code (DTC):
1) The voltage at pin A137:28 is above normal value

Observable symptoms
1) Ammonia smell can occur if the aftertreatment diesel exhaust fluid (DEF) warmed too much

Probable cause
1) Short circuit to voltage supply, Control wire (-)
2) Short circuit to 5V, Control wire (-)
3) Wiring harness
4) Aftertreatment Diesel Exhaust Fluid (DEF) Line Heater 1
