Volvo All Engines (2010 Emissions) Fault Code: SPN 3250 FMI 14 PID: DPF Spark Assisted Flame Temperature Sensor – Least Severe Level

Posted by PerDiezel Solutions on June 4, 2026

This fault indicates failure of the combustion flame to ignite. When aftertreatment diesel particulate filter (DPF) regeneration is active the aftertreatment control module (ACM) activates the ignition coil, aftertreatment DPF atomization module and air valves in order to create a flame in the aftertreatment DPF combustion chamber. The flame temperature is monitored continually by the ACM. To verify combustion the ACM measures the rise in flame temperature during the first 10 seconds of combustion. If proper combustion during the first 10 seconds of operation is not achieved the fault will be set.

Conditions for diagnostic trouble code (DTC):
1) Lost flame

Observable symptoms
1) Regeneration aborted

Probable cause
1) Aftertreatment Hydrocarbon Doser
