Volvo All Engines (2013 Emissions) Fault Code: P112B00 PID: EMS Turbocharger/Suprecharger Actuator “A” Temperature High

Volvo All Engines (2013 Emissions) Fault Code: P112B00 PID: EMS Turbocharger/Suprecharger Actuator “A” Temperature High

Circuit description
The (VGT) Variable Geometry Turbocharger Actuator is a self-contained component with motors, sensors and a control unit.

The (VGT) Variable Geometry Turbocharger uses a movable nozzle to adjust the intake manifold pressure for various operating conditions. Nozzle movement is controlled by an actuator mounted on the tubocharger. When the Engine Control Module (ECM) Relay is energized, a fuse supplies battery voltage to the (VGT) Variable Geometry Turbocharger and the unit is grounded by means of the engine block.

Conditions for diagnostic trouble code (DTC)
High actuator temperature

Observable symptoms
None

Probable cause
1) Variable Geometry Turbo temperature too high
2) Variable Geometry Turbo
