Volvo All Engines (2013 Emissions) Fault Code: P2A1E14 PID: EMS Injection Pump Fuel Metering Control “F” (Cam/Rotor/Injector)

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 circuit.

Conditions for diagnostic trouble code (DTC):
1) Circuit Short To Ground or Open

Observable symptoms
1) Low Power
2) Engine runs unevenly or misfires
3) Abnormal noise
4) Engine is operating on only 3 or 5 cylinders

Probable cause
1) Connector
2) Wiring harness
3) Injector
4) Engine control module (ECM)

Volvo All Engines (2013 Emissions) Fault Code: P2BA700 PID: EMS NOx Exceedence – Empty Reagent Tank

Observable symptoms
1) Engine de-rated
2) Major power loss
3) Low turbocharger boost
4) Engine is running but could be difficult to start in cold conditions

Volvo All Engines (2013 Emissions) Fault Code: P2BA800 PID: ACM NOx Exceedence – Interruption of Reagent Dosing Activity

This DTC is a legal requirement and is set when the emission standards are not met

The DTC will only become active when related DTCs are set. In order to correct the active DTC P2BA8-00, related DTCs must be corrected first

When the problem is resolved, this?DTC will be stored as inactive in the?control module?for?400 days, it cannot be erased

??Note: No workshop actions are needed when the DTC P2BA8-00 is inactive
