Volvo All Engines (2017 Emissions) Fault Code: P103B00 PID: EMS Reagent Dosing Valve Inducement
Volvo All Engines (2017 Emissions) Fault Code: P103B00 PID: EMS Reagent Dosing Valve Inducement
Circuit description
When the aftertreatment selective catalytic reduction (SCR) system operates under normal conditions, the aftertreatment control module (ACM) monitors diesel exhaust fluid (DEF) dosing valve duty cycle and DEF pump control value. When the DEF dosing valve duty cycle increases above allowed threshold and the DEF pump control value decreases below expected threshold, the ACM stops DEF dosing and reports a fault. The fault might be indication of electrical failure or blockage in DEF dosing valve or DEF supply line from the DEF tank.
Conditions for diagnostic trouble code (DTC)
Clogged or damaged component
Observable symptoms
No DEF Dosing
Engine de-rated
Probable cause
1) Contaminated fluid, (DEF)
2) Aftertreatment diesel exhaust fluid (DEF) dosage valve
3) Aftertreatment Diesel Exhaust Fluid (DEF) Pump
4) Aftertreatment diesel exhaust fluid (DEF) line
