Volvo All Engines (2013 Emissions) Fault Code: P02E300 PID: EMS Diesel Intake Air Flow Control Circuit High

Circuit description
The intake throttle valve controls the amount of fresh air that is mixed with the EGR gases that enter the engine to maintain appropriate engine emissions. The air flow is controlled by an electric motor that positions a movable plate. The plate position is monitored and communicated to the Electronic Control Module (ECM) by the throttle position sensor. The ECM supplies voltage to the electric motor to position the plate as the conditions require

Conditions for diagnostic trouble code (DTC)
Short circuit to battery voltage – A14.EB:5, EB:1

Diagnostic operating conditions
Ignition key in ON position

Observable symptoms
Loss of power
Engine shutdown
Heating failure

Probable cause
1) Connector
2) Wiring harness
3) Diesel Intake Air Flow Control
4) Engine Control Module (ECM)
