INTRODUCTION
This article covers basic description and operation of engine
performance-related systems and components. Read this article before
diagnosing vehicles or systems with which you are not completely
familiar.
AIR INDUCTION SYSTEM
NON-TURBOCHARGED ENGINES
Mirage equipped with 1.5L engine uses a Manifold Absolute
Pressure (MAP) sensor instead of a Volume Airflow (VAF) sensor.
Filtered air is ducted to a plenum-mounted throttle body.
All other models use same basic air induction system using a
remote air filter (with VAF sensor) connected to a plenum-mounted
throttle body.
TURBOCHARGED ENGINES
In addition to basic air induction system, turbocharging
system components include turbocharger(s), charge air cooler(s), air\
by-pass valve(s), wastegate actuator(s), wastegate control solenoid
valve(s) and intake duct(s).
Wastegate Control Solenoid Valve(s)
Powertrain Control Module (PCM) energizes solenoid valve(s)\
,
controlling bleed-off rate of turbocharger pressure by wastegate
actuator(s).
COMPUTERIZED ENGINE CONTROLS
Sequential Fuel Injection (SFI) is a computerized engine
control system, which controls fuel injection, ignition timing, idle
speed and emission control systems.
POWERTRAIN CONTROL MODULE (PCM)
PCM, also known as Engine Control Module (ECM), receives and
processes signals from input devices. Operating conditions such as
cold starting, altitude, acceleration and deceleration affect input
device signals. Based on signals received, PCM sends signals to
various components, which control fuel injection, ignition timing,
idle speed and emission control systems. For PCM location, see
PCM LOCATION table.

FUEL SYSTEM
FUEL DELIVERY
Electric fuel pump, located in gas tank, feeds fuel through
in-tank fuel filter, external fuel filter (located in engine
compartment) and fuel injector rail.
Fuel Pump
Fuel pump consists of a motor-driven impeller. Pump has an
internal check valve to maintain system pressure, and a relief valve
to protect fuel pressure circuit. Pump receives voltage supply from
MFI control relay.
Fuel Pressure Control Solenoid Valve (Turbo)
Valve prevents rough idle due to fuel percolation. On engine
restart, if engine coolant or intake air temperature reaches a preset
value, PCM applies voltage to fuel pressure control solenoid valve for
2 minutes after enginerestart. Valve will open, allowing atmospheric
pressure to be applied to fuel pressure regulator diaphragm. This
allows maximum available fuel pressure at injectors, enriching fuel
mixture and maintaining stable idle at high engine temperatures.
Fuel Pressure Regulator
Located on fuel injector rail, this diaphragm-operated relief
valve adjusts fuel pressure according to engine manifold vacuum.
As engine manifold vacuum increases (closed throttle), fuel

inspection procedures.
A visual inspection is made to determine if any required
emission control devices are missing, modified or disconnected.
Missing, modified or disconnected systems must be made fully
operational before a vehicle can be certified.
POSITIVE CRANKCASE VENTILATION (PCV)
PCV controls the flow of crankcase fumes into the intake
manifold while preventing gases and flames from traveling in the
opposite direction. PCV is either an open or closed system. See Fig. 2
.
Ensure PCV system is installed as required. Verify valve,
required hoses, connections, flame arresters, etc., are present,
routed properly and in serviceable condition.
Fig. 2: Typical Open & Closed Type PCV System
THERMOSTATIC AIR CLEANER (TAC)
The TAC supplies warm air to air intake during cold engine
operation. This system is active during cold engine warm-up only.
Under all other operating conditions, air cleaner function is the same
as any non-thermostatic unit.
Ensure required exhaust shroud, hot air duct, vacuum hoses
and air cleaner components are present and installed properly. See
Fig. 3 . Ensure any required thermostatic vacuum switches are in place
and vacuum hoses are installed and in serviceable condition. Also
ensure air cleaner lid is installed right side up. Check for oversized
air filter elements and for additional holes in the air cleaner
housing.
