Volvo All Engines (2013 Emissions) Fault Code: P240F00 PID: EMS EGR Slow Response

This function is used to calculate the EGR Mass Flow. The Engine Control Module (ECM) monitors the EGR diffpressure sensor and the EGR temperature sensor after cooler and uses these signals to calculate the EGR Mass Flow data.

Conditions for diagnostic trouble code (DTC):
1) EGR mass flow above calculated value
2) EGR mass flow is below calculated value

Observable symptoms
1) Exhaust smoke

Probable cause
1) EGR Valve

Volvo All Engines (2013 Emissions) Fault Code: P241E00 PID: ACM Reductant Heater Coolant Control Valve Stuck Closed

Circuit description
This diagnostic trouble code (DTC) indicates malfunction in the aftertreatment diesel exhaust fluid (DEF) tank heater valve or related wiring. The function of the aftertreatment DEF tank heater valve is to allow engine coolant flow to the aftertreatment DEF tank heater element which keeps the DEF from freezing. Frozen DEF may result in no DEF dosing which causes limited vehicle operation.

Conditions for diagnostic trouble code (DTC)
Aftertreatment diesel exhaust fluid (DEF) temperature too low

Observable symptoms
Possible engine de-rate

Probable cause
1) Mechanical fault
2) Damaged or restricted actuator coolant lines
3) Aftertreatment diesel exhaust fluid (DEF) tank heater valve

Volvo All Engines (2013 Emissions) Fault Code: P242800 PID: EMS Exhaust Gas Temperature Too High

This diagnostic function indicates malfunction at the exhaust gas temperature (EGT) sensor. The purpose of the exhaust gas sensor is to contribute the relevant temperatures required for the temperature regulated aftertreatment diesel particulate filter regeneration control. A faulty EGT sensor can result with a failed aftertreatment (DPF) regeneration.

Conditions for diagnostic trouble code (DTC):
1) High exhaust temperature, pre-catalyst

Observable symptoms
1) Low Power

Probable cause
1) Resistance too high, Wiring harness
2) Restricted catalyst
3) Charge air system leakage
4) Exhaust Gas Temperature (EGT) Sensor

Detailed information
1) Engine derate according to error torque map
2) Basic checks

Volvo All Engines (2013 Emissions) Fault Code: P242A15 PID: ACM Exhaust Gas Temperature Sensor Bank 1 Sensor 3

Circuit description
This diagnostic function indicates malfunction at the exhaust gas temperature (EGT) sensor. The purpose of the exhaust gas sensor is to contribute the relevant temperatures required for the temperature regulated aftertreatment diesel particulate filter regeneration control. A faulty EGT sensor can result with a failed aftertreatment (DPF) regeneration.

Conditions for diagnostic trouble code (DTC)
The voltage at pin A137:39 is less than 0.147705?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, Ground wire
4) Short circuit to voltage supply, signal wire
5) Wiring harness between component connector and electronic control unit (ECU) connector
6) Exhaust Gas Temperature (EGT) Sensor
7) Aftertreatment Control Module (ACM)

Volvo All Engines (2013 Emissions) Fault Code: P242A64 PID: EMS Exhaust Gas Temperature Sensor Bank 1 Sensor 3

Circuit description
This diagnostic function indicates malfunction at the exhaust gas temperature (EGT) sensor. The purpose of the exhaust gas sensor is to contribute the relevant temperatures required for the temperature regulated aftertreatment diesel particulate filter regeneration control. A faulty EGT sensor can result with a failed aftertreatment (DPF) regeneration.

Conditions for diagnostic trouble code (DTC)
The sensor value is not within an expected range
Too high of temperature difference compared to the other DPF temperature sensors

Observable symptoms
Regeneration not possible

Probable cause
1) Exhaust system leakage
2) Aftertreatment exhaust gas temperature (EGT) sensors installed in the incorrect location on the aftertreatment 3) diesel particulate filter (DPF)
4) Connector
5) Wiring harness
6) Exhaust Gas Temperature (EGT) Sensor
