Volvo All Engines (2017 Emissions) Fault Code: P110286 PID: EMS Reductant Pump “A” Control Circuit Electrical
Volvo All Engines (2017 Emissions) Fault Code: P110286 PID: EMS Reductant Pump “A” Control Circuit Electrical
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.
