VEHICLE IDENTIFICATION AND GENERAL SPECIFICATIONS
1. VEHICLE IDENTIFICATION
When purchasing spare parts or when
registering
or insuring a vehicle, it may be necessary to quote
various vehicle identification codes. The location of
these codes are as follows: The Engine Number is stamped on the front
face
of the engine block below No. 4 spark plug. The Chassis Number is stamped on the bulkhead
above and to the right of the brake booster. The Vehicle Identification Plate is located on the
bulkhead to the left of the MAP sensor and contains
codings relating to body style, engine capacity,
model,
transaxle type, engine number, paint, trim and build
date. The Compliance Plate contains information on
the vehicle make, model, month and year of manu-
facture, chassis number, seating, capacity and the
Australian Design Rules (ADR) with which the vehi-
cle complies. This plate is affixed to the bulkhead
above and to the left of the brake booster. The Tire Placard, which is located on the inside
of the glove compartment, contains information
on
the tire size, rim size, tire pressure and load ratings.

Fuel and Engine Management
(4) MAP sensor faulty or supply hose discon-
nected or blocked: Check the vacuum supply hose.
Check the operation of the MAP sensor.
EXCESSIVE FUEL CONSUMPTION
(1) Blocked air cleaner element: Check the ele-
ment and clean or renew as necessary.
(2) Incorrect fuel pressure: Check the fuel pump
and fuel pressure regulator. (3) Faulty coolant temperature sensor: Check
the connections and operation.
(4) Leaks in the fuel supply system: Check the
connections and components for leakage. (5) Leaking fuel injector(s): Clean or renew the
faulty injector(s). (6) Engine operating temperature too low:
Check the thermostat and electric cooling fan as
described in the Cooling an d Heating Systems section.
2. DESCRIPTION
The engine management system on the range of
vehicles covered by this manual controls the opera-
tion of the ignition system and the fuel system.
The central component of the engine management
system is the electronic control unit (ECU). The con-
trol unit is a micro-computer which controls the igni-
tion timing and the amount of fuel injected according
to signals received from various sensors. As changes
are detected in engine load and speed, coolant tem-
perature, barometric pressure, air temperature (1.8
liter engine), throttle position and vehicle speed, the
control unit alters the ignition timing and the fuel
injection amount to achieve optimum engine effi-
ciency.
The control unit incorporates a self diagnosis
mode which stores and displays codes relating to
certain system malfunctions. Whenever power is sup-
plied to the control unit, the control unit performs a

Ensure that all fuel connections are securely tightened.
