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):1) Mechanical system not responding properly Observable symptoms1) Engine de-rated2) Regeneration not possible Probable cause1) Incorrect installation or...

Electronic Viscous Fan: The Electronic Fan Drive contains a solenoid that controls the flow of fluid between reservoirs in the fan drive housing and cover. The Engine Control Module (ECM) provides a (PWM) Pulse Width Modulation signal to the solenoid and controls solenoid operation to optimize fan speed, based on coolant temperature, intake air temperature and A/C load. Conditions for diagnostic trouble code (DTC):1) The fan solenoid valve is activated because the control wire is shorted to ground2) Short circuit to ground on A14.EB:49 Observable symptoms1) Engine fan constantly engaged2) High fuel consumption3) Abnormal noise4) Coolant temperature below normal5) Low...
