Volvo All Engines (2017 Emissions) Fault Code: P103B00 PID: EMS Reagent Dosing Valve Inducement Circuit descriptionWhen 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...

Volvo All Engines (2017 Emissions) Fault Code: P103C00 PID: EMS SCR NOx Catalyst Efficiency Inducement Circuit descriptionThe 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 Conditions for diagnostic trouble code (DTC)Too high NOx emissions Probable cause1) Contaminated fluid2) Faulty Combined tank unit3) Aftertreatment diesel exhaust fluid (DEF) line4) Exhaust leakage5) Selective catalytic...

Volvo All Engines (2017 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...

Volvo All Engines (2017 Emissions) Fault Code: P109300 PID: EMS Engine Oil Pressure Moderately Low The Engine Oil Pressure Sensor is used to detect engine lubrication system failures. The sensor consists of a pressure sensitive diaphragm and amplifier. Engine oil pressure causes the sensor’s diaphragm to deflect and produce an electrical signal proportional to the pressure. The diaphragm deflection signal is amplified in the sensor.The sensor’s signal 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...
