Volvo All Engines (2013 Emissions) Fault Code: P114700 PID: EMS Fuel/Rail System Bank 1 Presure – Moderately Too High

Conditions for diagnostic trouble code (DTC):
1) The component is stuck in opened position

Observable symptoms
1) Low torque
2) Common rail safety valve: The safety valve is open

Probable cause
1) Wiring harness between component connector and electronic control unit (ECU) connector
2) Damaged connector
3) Damaged or faulty component
4) Injector

Volvo All Engines (2013 Emissions) Fault Code: P114800 PID: EMS Lost Communication With ECM According To Turbocharger/Supercharger Control Module “A”

The (VGT) Variable Geometry Turbocharger Actuator is a self-contained component with motors, sensors and a control unit.
The (VGT) Variable Geometry Turbocharger uses a movable nozzle to adjust the intake manifold pressure for various operating conditions. Nozzle movement is controlled by an actuator mounted on the tubocharger. When the Engine Control Module (ECM) Relay is energized, a fuse supplies battery voltage to the (VGT) Variable Geometry Turbocharger and the unit is grounded by means of the engine block.

Conditions for diagnostic trouble code (DTC):
1) Actuator command missing, message from engine control module (ECM) not available for 75 milliseconds or more

Observable symptoms
1) Low Power

Probable cause
1) CAN7 Data link failure
2) Loss of voltage or ground connection to the actuator
3) Actuator
4) Engine control module (ECM)

Detailed information
1) The nozzle goes to 100% position (open), resulting in low intake manifold pressure and low power

Volvo All Engines (2013 Emissions) Fault Code: P114970 PID: EMS Intake Air Heater “B” Circuit

The preheat function is used to warm up the inlet air during cold conditions both before and after cranking to make the starting easier and better for the environment at very low temperatures. This diagnostic trouble code (DTC) detects a faulty preheat function.

Conditions for diagnostic trouble code (DTC):
1) The voltage at pin A14.EB:14 is more than 91?% battery voltage

Diagnostic operating conditions
1) Ignition key in ON position

Observable symptoms
1) Intake air heater (IAH) relay may be constantly activated
2) High intake air temperature (IAT)
3) High current consumption
4) Power loss
5) Low battery voltage

Probable cause
1) Wiring harness
2) Connector
3) Intake air heater (IAH) relay

Volvo All Engines (2013 Emissions) Fault Code: P11497E PID: EMS Intake Air Heater “B” Circuit

The preheat function is used to warm up the inlet air during cold conditions both before and after cranking to make the starting easier and better for the environment at very low temperatures. This diagnostic trouble code (DTC) detects a faulty preheat function.

Conditions for diagnostic trouble code (DTC)
Intake air heater (IAH) relay not activated
The voltage at pin A14.EB:14 is more than 91?% battery voltage

Observable symptoms
Intake air heater (IAH) relay may be constantly activated
High intake air temperature (IAT)
High current consumption
Low battery voltage

Probable cause
1) Wiring harness
2) Connector
3) Intake air heater (IAH) relay

Volvo All Engines (2013 Emissions) Fault Code: P114B00 PID: EMS Turbocharger/Supercharger Actuator “A” temperature Low

The (VGT) Variable Geometry Turbocharger Actuator is a self-contained component with motors, sensors and a control unit.
The (VGT) Variable Geometry Turbocharger uses a movable nozzle to adjust the intake manifold pressure for various operating conditions. Nozzle movement is controlled by an actuator mounted on the tubocharger. When the Engine Control Module (ECM) Relay is energized, a fuse supplies battery voltage to the (VGT) Variable Geometry Turbocharger and the unit is grounded by means of the engine block.

Conditions for diagnostic trouble code (DTC):
1) High actuator temperature

Probable cause
1) Foreign objects caught in the mechanism
2) Seized linkage
3) Turbo nozzle binding due to soot or damaged turbo

Volvo All Engines (2013 Emissions) Fault Code: P115000 PID: EMS Throttle/Pedal Position Sensor/Switch “A/D” Voltage Correlation

An analog signal from the accelerator pedal is used to indicate a percent value of the accelerator pedal position. The signal is monitored by the Vehicle Electronic Control Unit (VECU) and communicated to the Engine Control Module (ECM) via the J1939 data link. Based on the signal, the ECM will request a certain engine torque. If the analog signal is too low or too high, the ECM instead uses the digital signal from the accelerator pedal’s idle validation switch to enable driving in limp home mode.

Conditions for diagnostic trouble code (DTC):
1) No signal : Idle validation switch IVS 2
2) 0-22% : Accelerator pedal

Observable symptoms
1) The engine does not respond when accelerator pedal is pressed.

Probable cause
1) Wiring harness between sensor connector and Engine Control Module (ECM)
2) Connector
3) Accelerator pedal
4) Vehicle Control Unit (VECU)

Volvo All Engines (2013 Emissions) Fault Code: P115100 PID: EMS Aftertreatment System Over Temperature

Conditions for diagnostic trouble code (DTC):
1) The voltage at pin A14.EA:3 is less than 0.5?V

Diagnostic operating conditions
1) Ignition key in ON position

Observable symptoms
1) The fuel pump is permanently engaged
2) Water drainage is not possible

Probable cause
1) Wiring harness
2) Connector
3) Pump
4) Engine control module (ECM)
