Volvo All Engines (2013 Emissions) Fault Code: P111000 PID: EMS Engine Stop Switch Performance Or Incorrect Operation

Conditions for diagnostic trouble code (DTC)
The function is monitored by the diagnostic system when the vehicle is being driven
Electronic control unit (ECU) connector A14.EA:27 monitors the function

Observable symptoms
The stop switch does not work

Probable cause
1) Engine stop switch
2) Connector
3) Open circuit electric cables

Volvo All Engines (2013 Emissions) Fault Code: P111186 PID: EMS Exhausy Gas Temperature Sensor Bank 1 Sensor 1 Electrical

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) The sensor signal is stuck
2) Sensor value does not change with changing conditions

Observable symptoms
1) Regeneration not possible

Probable cause
1) Aftertreatment exhaust gas temperature (EGT) sensors installed in the incorrect location on the aftertreatment diesel particulate filter (DPF)
2) Pre-catalyst, Exhaust Gas Temperature (EGT) Sensor

Volvo All Engines (2013 Emissions) Fault Code: P111600 PID: EMS Manifold Absolute Pressure Moderately Too High

The Boost Air Pressure Sensor is used to monitor the pressure of the air in the intake system after the turbocharger. The sensor consists of a pressure sensitive diaphragm/amplifier sensor. Air pressure causes the sensors diaphragm to deflect and produce an electrical signal proportional to the pressure. The diaphragm deflection signal is amplified in the sensor.
The sensor signals are used to calculation fuel injection and is monitored by the Engine Control Module (ECM).
The engine control module (ECM) will set a diagnostic trouble code (DTC) and derate the engine to avoid engine damage if the sensor signal is not within predetermined limits, or the signal is not rational.

Conditions for diagnostic trouble code (DTC):
1) Charge pressure High

Observable symptoms
1) Engine derate according to error torque map

Probable cause
1) Actuator
2) Intake manifold air temperature (IMAT) and pressure sensor
3) By-pass shutter

Volvo All Engines (2013 Emissions) Fault Code: P111900 PID: EMS Intake Manifold Temperature Moderately Too High

The Intake Air Temperature and Humidity Sensor contains two thermistors, and the resistance of each thermistor varies inversely to temperature. By monitoring the current flow through each thermistor, the Engine Control Module (ECM) calculates the temperature and humidity of the air entering the turbocharger.
The Engine Control Module (ECM) uses values from the Intake Air Temperature (IAT), Intake Manifold Pressure (IMP) and compressor efficiency to calculate the Compressor Discharge Temperature.

Conditions for diagnostic trouble code (DTC):
1) Charge air temperature too high

Probable cause
1) Intake manifold air temperature (IMAT) and pressure sensor
2) Extreme driving conditions
3) Poor cooling

Detailed information
1) High ambient temperature can cause an active diagnostic trouble code (DTC)
