Volvo All Engines (2013 Emissions) Fault Code: P245400 PID: ACM Aftertreatment 1 Diesel Particulate Filter Differential Pressure Circuit Low

Volvo All Engines (2013 Emissions) Fault Code: P245400 PID: ACM Aftertreatment 1 Diesel Particulate Filter Differential Pressure Circuit Low

Circuit description
The function identifies and indicates malfunction of the aftertreatment diesel particulate filter (DPF) by analyzing the pressure drop over the aftertreatment DPF. This is done by making a check for deviation between sensor value and a model pressure drop. In some extreme cases the engine will derate.

Conditions for diagnostic trouble code (DTC)
The voltage at pin A137:26 is less than 0.27?V

Diagnostic operating conditions
Ignition key in ON position

Observable symptoms
Regeneration not possible

Probable cause
1) Connector
2) Open circuit, Signal wire
3) Open circuit, Supply wire
4) Short circuit to ground, Signal wire
5) Wiring harness
6) Aftertreatment DPF Differential Pressure Sensor
7) Aftertreatment Control Module (ACM)
