Volvo All Engines (2013 Emissions) Fault Code: P102A00 PID: EMS Cold Start Fuel injection Quanitity Lower Than Expected

Fuel Injector operation is controlled by the Engine Control Module (ECM). The ECM provides a common supply voltage to injectors 4,5,6 (Bank 2) and there are individual output transistor drivers inside the ECM to control each individual injector?s ground circuits. There are two solenoid circuits within the injector; a Needle Control Valve and a Spill Valve. Although they are separate circuits, the same fault code is used to identify a fault in the Needle Control Valve circuit and/or the Spill Valve circuit.

Conditions for diagnostic trouble code (DTC):
1) The NOx sensor indicates the following oxygen level: High

Probable cause
1) Poor fuel quality
2) Air in the fuel system
3) EGR Valve Stuck in closed position
4) Exhaust system leakage
5) Coolant Leak in: Air line
6) Coolant Leak in: Combustion air line
7) Low compression
8) Lean mixture

Volvo All Engines (2013 Emissions) Fault Code: P103400 PID: EMS Particulate Matter Sensor System Voltage Too High

Circuit description
The aftertreatment particulate sensor measures the amount of particulates in the exhaust system. The aftertreatment particulate sensor is connected to the DL7 data link. The Diagnostic Trouble Code (DTC) indicates an aftertreatment particulate sensor supply failure. For example: Aftertreatment particulate sensor voltage too low, or voltage too high

Volvo All Engines (2013 Emissions) Fault Code: P103B00 PID: EMS Reagent Dosing Valve Inducement

Circuit description
When the aftertreatment selective catalytic reduction (SCR) system operates under normal conditions, the aftertreatment control module (ACM) monitors diesel exhaust fluid (DEF) dosing valve duty cycle and DEF pump control value. When the DEF dosing valve duty cycle increases above allowed threshold and the DEF pump control value decreases below expected threshold, the ACM stops DEF dosing and reports a fault. The fault might be indication of electrical failure or blockage in DEF dosing valve or DEF supply line from the DEF tank.

Conditions for diagnostic trouble code (DTC)
Clogged or damaged component

Observable symptoms
No DEF Dosing
Engine de-rated

Probable cause
1) Contaminated fluid, (DEF)
2) Aftertreatment diesel exhaust fluid (DEF) dosage valve
3) Aftertreatment Diesel Exhaust Fluid (DEF) Pump
4) Aftertreatment diesel exhaust fluid (DEF) line

Volvo All Engines (2013 Emissions) Fault Code: P103C00 PID: EMS SCR NOx Catalyst Efficiency Inducement

Circuit description
The NOx sensor measures the amount of NOx in the exhaust system. The NOx sensor is connected in the J2284/ISO data link. This diagnostic trouble code (DTC) indicates a NOx monitoring failure. For example; NOx sensor short- or open circuit, NOx sensor removed, NOx sensor missing signal..This function indicates that the NOx conversion efficiency is not correct

Volvo All Engines (2013 Emissions) Fault Code: P108600 PID: EMS Oil Level Moderately Low

The Engine Oil Temperature/Level Sensor contains two resistors: One for engine oil temperature and one for engine oil level.
Diagnostic trouble code (DTC) Placeholder will be present only when a problem with the engine oil level (EOL) circuit has failed. Please reference Placeholder for engine oil temperature (EOT) sensor circuit diagnostics.
The resistance of the engine oil level portion of the sensor changes inversely to the level of the engine oil. The Engine Control Module (ECM) monitors the voltage drop across the sensor and uses this signal to warn that the engine oil level is not within programmed limits. In some cases the engine will derate.
The engine oil level is monitored when the key is on, before the starter is engaged. If low engine oil is detected, either from parking on an incline, or actual low oil, the code will remain active until the next key cycle. It is important that the vehicle is level during key on, or the low engine oil level code may remain.

Conditions for diagnostic trouble code (DTC):
1) Engine oil level (EOL) is below warning level

Probable cause
1) Vehicle Not Parked On a Level Surface.
2) Low oil level
3) Connector
4) Engine Oil Dipstick
5) Engine oil level (EOL) and temperature sensor

Detailed information
1) Engine may have to be off up to 20 minutes depending on temperature before checking the oil level.
