ngine Management System Components
Electronic Throt
tle
The
electronic throttle assembly, in resp
onse to signals from both the driver and the ECM, adjusts idle speed, sets the
throttle valve to the position requested by the driver's accelerator / throttle pedal, cruise and traction control, power
limitation and catalyst warm-up.
Mass
Air Flow Meter
The sensor i
s located in the air flow mete
r assembly and outputs an analogue voltag e to the ECM. This sensor measures air
flow into the engine inlet system and is calibrated to measure kg / hour.
In
take Air Temperature
Th
e intake air temperature sensor is loca
ted in the air flow meter assembly and outputs an analogue voltage to the ECM.
The ECM will substitute a default value eq ual to 50°C should this sensor fail.
Fuel Injectors
The eigh
t bottom fed fuel injectors are located in the fuel rails. Th
e fuel injectors are electromagnetic solenoid valves
controlled by the ECM. The pulse time for the injector combined with the fuel pr essure determines the volume of fuel
injected to the manifold.
Fue
l Delivery
The fu
el pump provides fuel to the fuel rail where the circulat
ing pressure is controlled by a pressure regulator valve; excess
fuel is returned to the fuel tank.
The pressure regulator valve is controlled by manifold depression so that fuel delivery pressure is maintained at
approximately 3 bar above manifold pressure.
Fuel Pump
Relay
The ECM controls thi

s component for normal
engine running. The security system may disable this relay via communication
with the ECM.
Fuel Lev
el Sensing
The tank fuel

is measured by the fuel le
vel sensor . This signal is used by the ECM as an in put to certain diagnostics.
Eva
porative Valve
Excess vapour

formed in the fuel tank is
absorbed into the evaporative emission pu rge control canister. While the engine is
running, the fuel absorbed in the canister is gradually purged back into the engine. The rate of purging is governed by
engine operating conditions and vapour concentration level. Operating conditions which affect the purge rate are:

1. Open the engine compartment and fit paintwork protection
sheets.
2. Set the engine compartment cover to the service access
position.
3. Remove the drive belt from the fro nt accessory drive. Refer to
Operation 12.10.40.
4. Remove the twin fan and motor assembly for access. Refer to
Operation 26.25.12
5. CAUTION: Under no circumstan ces should the crankshaft
setting peg 303-531 be used in the following operations, to lock
the crankshaft.
• NOTE: Should extra locking of the crankshaft be required, use a
lever against one torque converte r boss. Remove the plastic mesh
cover from the torque converter housing for access.

3.
If
the damper is not to be installed immediately, the transit
ring should be installed temporarily to the seal.

4. Install a new O-ri
ng seal to the damper.

5. Instal
l the crankshaft damper.
Apply petroleum jelly to the damper

bore and O-ring seal.

1. Install the damper onto the crankshaft.
2. Install the split locking ring onto the crankshaft,
inside the centre bo re of the damper.
3. Install, but do not tigh ten, a new damper securing
bolt.

6. CAUTIO
N: Under no circumstan
ces should the crankshaft
setting peg 303-531 be used in the following operations, to lock
the crankshaft.
Tighten the damper securing bolt. 1. Reposition the damper to allow access to the bolt holes for installing the locking tool.
2. Install the locking tool (303-01 and 303-01-02) to the
