Volvo All Engines (2017 Emissions) Fault Code: P029800 PID: EMS Engine Oil Over Temperature Circuit descriptionThe Engine Oil Level/Temperature Sensor contains two thermistors, one for engine oil temperature and one for engine oil level. The resistance of the engine oil temperature portion of the sensor changes inversely to the temperature of the engine oil. When the engine oil is cold, the sensor resistance is high. As the temperature of the engine oil increases, the sensor resistance decreases.The Engine Control Module (ECM) monitors the voltage drop across the sensor and uses this signal to warn the driver and derate the engine...

Volvo All Engines (2017 Emissions) Fault Code: P029900 PID: EMS Turbocharger/Supercharger Underboost The engine control module (ECM) monitors the intake manifold pressure (IMP) sensor and controls the boost air system (mainly controlled by the VGT) and the engine turbocharger compressor bypass valve. The ECM also uses parameters like engine speed (RPM) and turbocharger speed to make a calculation of the IMP. This estimated value should not differ too much from the measured value. Conditions for diagnostic trouble code (DTC):1) Charge pressure Low Observable symptoms1) High soot level2) Low Power Probable cause1) Charge air system leakage2) Turbocharger3) Charge air pressure sensor4)...

Volvo All Engines (2017 Emissions) Fault Code: P02CC00 PID: EMS Cylinder 1 Fuel Injector Offset Learning at Min Limit 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...
