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) Air Cleaner (ACL)5) Faulty VGT position – The sensor shows a more...

This diagnostic trouble code (DTC) is used to indicate temperatures at the engine control module (ECM). The DTC will be set if the ECM temperature is too high. A faulty ECM temperature can lead to power loss. Conditions for diagnostic trouble code (DTC):1) Internal fault in electronic control unit (ECU) Probable cause1) Engine control module (ECM) Volvo All Engines (2010 Emissions) Fault Code: SPN 1127 FMI 18 PID: PSID 98 Engine Turbocharger 1 Boost Pressure Volvo All Engines (2010 Emissions) Fault Code: SPN 1127 FMI 16 PID: PSID 98 Engine Turbocharger 1 Boost Pressure Volvo All Engines (2010 Emissions) Fault...
