This function is used to check if the Exhaust Gas Recirculation (EGR) temperature sensor is working and check the status on the EGR cooler. If the sensor should show a value above limit due to extreme driving or malfunction in the cooler, the Engine Control Module (ECM) will derate the engine to avoid damage. Conditions for diagnostic trouble code (DTC):1) Temperature above normal, EGR System Observable symptoms1) Engine de-rated Probable cause1) Temperature sensor, EGR Volvo All Engines (2010 Emissions) Fault Code: SPN 412 FMI 16 PID: Engine Exhaust Gas Recirculation Temperature Volvo All Engines (2010 Emissions) Fault Code: SPN 412...

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 cause1) Hose2) Pressure sensor3) Aftertreatment diesel exhaust fluid...
