To ensure an optimum torque curve, a Garrett turbocharger with variable turbine geometry
is used.

The movable guide vanes on the turbine wheel are adjusted by the turbocharger vacuum
canister by means of a connecting rod.

A position sensor is located centrally on the turbocharger vacuum canister; this forwards
the position of the guide vanes to the powertrain control module (PCM) as an input
variable.

The vacuum to the turbocharger vacuum canister is metered by the boost control solenoid
valve. The boost control solenoid valve is controlled by the PCM .

The bearings of the turbocharger are lubricated by the engine's oil circuit via a rigid oil pipe.

Diagnosis and Testing

Special Tool(s)

General Equipment

Inspection and Verification

NOTE: It is normal for a small amount of combustion gas to pass into the crankcase. This
gas is scavenged into the air intake system through the positive crankcase ventilation
(PCV) system, which incorporates an oil separator. Some engine oil, in the form of a
vapor is carried into the air intake system with the blow-by gases (this engine oil also
contributes to valve seat durability). This means that oil will collect inside the air intake
components and the turbocharger. This is not an indication that the turbocharger oil seal
has failed. The turbocharger oil seal will not fail unless the bearings fail first, which will
cause the turbocharger to become noisy or seize. Do not install a new turbocharger due
to oil inside the turbocharger or the air intake components. If a leak is detected in the oil
supply or return tubes or connections, locate and rectify the source. Do not install a new
turbocharger due to an oil leak.

1. 1. Verify the customer concern.

2. 2. Visually inspect for obvious signs of mechanical or electrical damage.
