Volvo All Engines (2017 Emissions) Fault Code: P056E00 PID: EMS Cold Start Turbocharger/Supercharger Boost Control “A” Performance
Volvo All Engines (2017 Emissions) Fault Code: P056E00 PID: EMS Cold Start Turbocharger/Supercharger Boost Control “A” Performance
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) Failure to start regulation of Variable Geometry Turbo (VGT) or Exhaust Gas Recirculation (EGR) system
Observable symptoms
1) None
Probable cause
1) Variable Geometry Turbo
