Volvo All Engines (2013 Emissions) Fault Code: P112E00 PID: EMS Exhaust Gas Temperature Moderately High Bank 1

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

Volvo All Engines (2013 Emissions) Fault Code: P113000 PID: EMS Exhuast Aftertreatment Fuel Air Purge Valve Stuck Closed

Aftertreatment Purge Air Valve
The Aftertreatment Hydrocarbon Dosing Module contains three non serviceable valves, the Aftertreatment Fuel Shutoff Valve, Aftertreatment Purge Air Valve and Aftertreatment Hydrocarbon Dosing Valve, and a serviceable Aftertreatment Fuel Pressure Sensor.

During Air Purge operation the Engine Control Module (ECM) sends a voltage signal to activate the Aftertreatment Purge Air Valve open. This allows air pressure to flow into the Aftertreament Hydrocarbon Dosing Module. The ECM then sends a PWM signal to the Aftertreatment Hydrocarbon Dosing Valve that allows purge air pressure to be monitored by a signal from the Aftertreatment Fuel Pressure Sensor to the ECM.

Conditions for diagnostic trouble code (DTC)
No air supply to the actuator Exhaust Aftertreatment Fuel System

Observable symptoms
None
Regeneration not possible or Regeneration aborted

Probable cause
1) No air supply to the actuator Exhaust Aftertreatment Fuel System
2) Exhaust Aftertreatment Fuel System Fuel line(s), Leakage
3) Air purge valve Exhaust Aftertreatment Fuel System Valve is not opening properly
