The CKP sensor is installed in the rear left side of the sump body, in line with the engine drive plate. The sensor is secured with a single screw and sealed with an O-ring. A two pin electrical connector provides the interface with the engine harness.

The head of the CKP sensor faces a reluctor ring pressed into the outer circumference of the engine drive plate. The reluctor ring has a 60 minus 2 tooth pattern. There are 58 teeth at 6° intervals, with two teeth removed to provide a reference point
with a centerline that is 21° BTDC (before top dead center) on cylinder 1 of bank A.
If the CKP sensor fails, the ECM:
Uses signals from the CMP sensors to determine the angular position of the crankshaft and the engine speed Adopts a limp home mode where engine speed is limited to a maximum of 3000 rev/min.

With a failed CKP sensor, engine starts will require a long crank time while the ECM determines the angular position of the crankshaft.

CAMSHAFT POSITION SENSORS



The CMP sensors are MRE (magneto resistive element) sensors that allow the ECM to determine the angular position of the camshafts. MRE sensors produce a digital output which allows the ECM to detect speeds down to zero. The four CMP sensors are installed in the front upper timing covers, one for each camshaft.
Each CMP sensor is secured with a single screw and sealed with an O-ring. On each CMP sensor, a three pin electrical connector provides the interface with the engine harness.
The head of each CMP sensor faces a sensor wheel attached to the front of the related VCT unit.

9 Journal - Drive plate/crankshaft location 10 Torque converter cover 11 Lock-up clutch piston 12 Lock-up clutch plate The torque converter is the coupling element between the engine and the transmission and is located in the bell housing, on
the engine side of the transmission. The driven power from the engine crankshaft is transmitted hydraulically and mechanically
through the torque converter to the transmission. The torque converter is connected to the engine by a drive plate attached to
the rear of the crankshaft.

The torque converter comprises an impeller, a stator and a turbine. The torque converter is a sealed unit with all components
located between the converter housing cover and the impeller. The two components are welded together to form a sealed, fluid
filled housing. With the impeller welded to the converter housing cover, the impeller is therefore driven at engine crankshaft
speed.

The converter housing cover has four threaded bosses, which provide for attachment of the engine drive plate. The threaded
bosses also provide for location of special tools which are required to remove the torque converter from the bell housing.

Impeller

Fluid Flow



Item Description 1 Turbine 2 Stator 3 Impeller When the engine is running the rotating impeller acts as a centrifugal pump, picking up fluid at its center and discharging it at
high velocity through the blades on its outer rim. The design and shape of the blades and the curve of the impeller body cause
the fluid to rotate in a clockwise direction as it leaves the impeller. This rotation improves the efficiency of the fluid as it
contacts the outer row of blades on the turbine.

The centrifugal force of the fluid leaving the blades of the impeller is passed to the curved inner surface of the turbine via the
tip of the blades. The velocity and clockwise rotation of the fluid causes the turbine to rotate.

Turbine

The turbine is similar in design to the impeller with a continuous row of blades. Fluid from the impeller enters the turbine
through the tip of the blades and is directed around the curved body of the turbine to the root of the blades. The curved
surface redirects the fluid back in the opposite direction to which it entered the turbine, effectively increasing the turning force
applied to the turbine from the impeller. This principle is known as torque multiplication.

When engine speed increases, turbine speed also increases. The fluid leaving the inner row of the turbine blades is rotated in
a counter-clockwise direction due to the curve of the turbine and the shape of the blades. The fluid is now flowing in the
opposite direction to the engine rotation and therefore the impeller. If the fluid was allowed to hit the impeller in this
condition, it would have the effect of applying a brake to the impeller, eliminating the torque multiplication effect. To prevent
this, the stator is located between the impeller and the turbine.

Item Description A Unlocked condition B Locked condition 1 Clutch plate 2 Clutch piston 3 Torque converter body 4 Turbine 5 Impeller 6 Stator 7 Piston chamber 8 Turbine chamber The lock-up clutch is a hydro-mechanical device which eliminates torque converter slip, improving fuel consumption. The
engagement and disengagement is controlled by the TCM to allow a certain amount of controlled 'slip'. This allows a small difference in the rotational speeds of the impeller and the turbine which results in improved shift quality. The lock-up clutch
comprises a piston and a clutch friction plate.

In the unlocked condition, the oil pressure supplied to the piston chamber and the turbine chamber is equal. Pressurized fluid
flows through a drilling in the turbine shaft and through the piston chamber to the turbine chamber. In this condition the clutch
plate is held away from the torque converter body and torque converter slip is permitted.

In the locked condition, the TCC spool valves are actuated by the EPRS. The fluid flow in the unlocked condition is reversed and the piston chamber is vented. Pressurized fluid is directed into the turbine chamber and is applied to the clutch piston.
The piston moves with the pressure and pushes the clutch plate against the torque converter body. As the pressure increases,
the friction between the clutch plate and the body increases, finally resulting in full lock-up of the clutch plate with the body.
In this condition there is direct mechanical drive from the engine crankshaft to the transmission planetary gear train.

FLUID PUMP

The fluid pump is an integral part of the transmission. The fluid pump is used to supply hydraulic pressure for the operation of
the control valves and clutches, to pass the fluid through the transmission cooler and to lubricate the gears and shafts.
The ZF 6HP28 fluid pump is a crescent type pump and is located between the intermediate plate and the torque converter. The
pump has a delivery rate of 16 cm3
per revolution.
