Volvo All Engines (2017 Emissions) Fault Code: P101400 PID: EMS Cold Start Cylinder 2 Fuel Injector Offset Learning at Min Limit

Circuit description
Fuel Injector operation is controlled by the Engine Control Module (ECM). The ECM provides a common supply voltage to injectors 1,2,3 (Bank 1) 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 circuit.

Conditions for diagnostic trouble code (DTC)
Injector (INJ) activated
Cylinder balancing data too high
Low Power
Uneven operation
Abnormal noise

Probable cause
1) Excessive wear or damage to cylinder liners, piston, or piston rings
2) Valves and rocker arms
3) Camshaft
4) VCB control valve sticking or slow to close
5) Injector 2
