VOLVOUU All Engines (2017 Emissions) Fault Code: P054E00 PID: EMS Idle Control System – Fuel Quantity Lower Than Expected
The Engine Control Module (ECM) monitors the crankshaft angular acceleration using the flywheel sensor. The ECM monitors the camshaft position sensor to determine the engine’s position. The ECM calculates the average value of crankshaft angular acceleration for all six cylinders and compares the value to each individual cylinder’s angular acceleration. If a cylinder’s acceleration value is outside a specified range the ECM interprets this as a misfiring cylinder. The crankshaft average angular acceleration value is used by the ECM to determine cylinder balancing and idle speed.
Conditions for diagnostic trouble code (DTC):
1) Calculated fuel consumption, Below normal
Observable symptoms
1) Abnormal fuel consumption
Probable cause
1) Fuel
2) Injector
3) The engine is running on engine oil
