Volvo All Engines (2010 Emissions) Fault Code: SPN 5394 FMI 14 PID: PSID 89 Aftertreatment DEF Dosing Valve
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):
1) The aftertreatment diesel exhaust fluid (DEF) dosing valve has frozen too many times
Observable symptoms
1) No aftertreatment diesel exhaust fluid (DEF) dosage
Probable cause
1) Aftertreatment diesel exhaust fluid (DEF) dosage valve
