Volvo All Engines (2013 Emissions) Fault Code: P203A13 PID: ACM Reductant Lever Sensor “A”

Circuit description
Aftertreatment Control Module (ACM) monitors DEF tank temperature and uses it to control the Aftertreatment DEF Tank Heater valve to keep the DEF from freezing.
Aftertreatment Diesel Exhaust Fluid (DEF) Tank, Level Sensor has an indicator lamp and gauge in the instrument cluster. A solid lamp comes on when there is approximately 16% DEF remaining in the tank. A flashing lamp indicates when there is approximately 4% DEF remaining in the tank. A 25% engine derate is possible if the DEF is not refilled above the red line on the gauge at the next engine start up.

Conditions for diagnostic trouble code (DTC)
Open circuit between Electronic Control Unit and Sensor

Observable symptoms
Engine de-rated

Probable cause
1) Connector
2) Wiring harness
3) Fuse: FT01
4) Fuse: FE5
5) Reductant Level Sensor “A”

Volvo All Engines (2013 Emissions) Fault Code: P203A13 PID: EMS Reductant Level Sensor “A”

Conditions for diagnostic trouble code (DTC):
1) Active DTCs in EATS System
2) Other DTCs detected may be the reason for the selected DTC to be set. The recommendation is to fault trace and repair the other DTCs first. Repairing the other detected DTCs may change selected DTC to inactive.

Action
1) Aftertreatment Control Module (ACM)
2) Fault trace active diagnostic trouble codes (DTCs) on above components

Volvo All Engines (2013 Emissions) Fault Code: P203A64 PID: EMS Reductant Level Sensor “A”

Circuit description
Aftertreatment Diesel Exhaust Fluid (DEF) Tank, Level Sensor has an indicator lamp and gauge in the instrument cluster. A solid lamp comes on when there is approximately 16% DEF remaining in the tank. A flashing lamp indicates when there is approximately 4% DEF remaining in the tank. A 25% engine derate is possible if the DEF is not refilled above the red line on the gauge at the next engine start up.

Conditions for diagnostic trouble code (DTC)
Low fluid level in the tank (Approximately?16%)
Low signal voltage from sensor

Probable cause
1) Low fluid level in the tank
2) Wiring harness
3) Aftertreatment diesel exhaust fluid (DEF) tank, Level Sensor, Temperature Sensor

Volvo All Engines (2013 Emissions) Fault Code: P203B00 PID: EMS Aftertreatment Reagent Level Warning

Circuit description
The reductant level sensor is integrated into the reductant quality module and monitors the level of DEF in the DEF tank.

Conditions for diagnostic trouble code (DTC)
The deviation between the highest and lowest levels in the DEF tank was monitored during a self-test of the following component(s): DEF quality, level and temperature sensor

Probable cause
1) Aftertreatment diesel exhaust fluid (DEF) tank, Level Sensor
2) Clogged DEF system
3) Aftertreatment diesel exhaust fluid (DEF) tank, Incorrect mounting
4) Aftertreatment DEF dosing valve

Volvo All Engines (2013 Emissions) Fault Code: P203D00 PID: ACM Aftertreatment Reagent Level Short Circit High

Circuit description
Aftertreatment Diesel Exhaust Fluid (DEF) Tank, Level Sensor has an indicator lamp and gauge in the instrument cluster. A solid lamp comes on when there is approximately 16% DEF remaining in the tank. A flashing lamp indicates when there is approximately 4% DEF remaining in the tank. A 25% engine derate is possible if the DEF is not refilled above the red line on the gauge at the next engine start up.

Conditions for diagnostic trouble code (DTC)
Voltage above normal or shorted high

Probable cause
1) Connector
2) Wiring harness
3) Short circuit to battery voltage, Signal wire
4) Short circuit to 5V, Signal wire
5) Aftertreatment diesel exhaust fluid (DEF) tank, Level Sensor, Temperature Sensor
