MAJOR DIFFERENCES
Major differences between the new 5S±FE engine and previous engine are listed below.
Item
Features
Engine ProperThe squish area of the combustion chamber in the cylinder head has been
optimised to improve torque in the low±to mid±speed range.
Cooling SystemAn aluminum radiator core is used for weight reduction.
Intake and Exhaust System
The ports of the manifold have been extended to improve torque in the low±
to mid±speed range.
The exhaust manifold is made of stainless steel plates for improve engine per-
formance and weight reduction.
Through the optimized allocation of the exhaust pipe supports, the number of
supports has been reduced from 5 to 4, thus reducing the noise and vibration
which are transmitted to the vehicle body.
Fuel SystemA fuel returnless system has been adopted to prevent the internal temperature
of the fuel tank from rising and to reduce evaporative emissions.
Ignition SystemThe DIS (Direct Ignition System) contributes to the powerful high output by
providing a powerful spark to the engine.
Engine MountingTo reduce noise and vibration and to improve drivability, the allocation of the
engine mounts*1 and their characteristics have been revised.
Engine Control System
The injection pattern for engine starting have changed form the 2 group
injection type to sequential multiport injection type.
In place of the oxygen sensor (bank 1, sensor 1), a new air fuel ratio sensor has
been adopted. *
2
The power steering idle±up control has been changed from the system using
an air control valve to the one using a pressure switch and an IAC valve.
Emission Control System
The EGR valve body has been changed from cast iron to aluminum alloy for
weight reduction.
A TWC (Three±Way Catalytic Converter) that is integrated with a stainless
steel exhaust manifold has been adopted.*
2
The TWC, which was previously installed below the exhaust manifold has
been discontinued.*3
*1: Only for Automatic Transaxle Models.
*
2: Only for California Specification Models.
*
3: Except for California Specification Models.

MAJOR DIFFERNCES
Major differences between the new 1MZ±FE engne and previous engine are listed below.
Item
Outline
Cooling SystemAn aluminum radiator core is used for weight reduction.
Intake and Exhaust System
Through the optimized allocation of the exhaust pipe supports, the number
number of supports has been reduced from 5 to 4, thus reducing the noise
and vibration which are transmitted to the vehicle body.
Fuel SystemA fuel returnless system has been adopted to prevent the internal temperature
of the fuel tank from rising, and to reduce evaporative emissions.
Engine MountingThe characteristics of the engine mounts, torque rod, and absorber have been
optimized to reduce noise and vibration.
Engine Control System
A communication circuit has been provided between the ECM and the
ABS & TRAC ECU in conjunction with the adoption of the TRAC
(Traction Control) system.*
The fuel pressure control has been discontinued in conjunction with the
adoption of the fuel returnless system.
Instead of using the IDL signal input from the throttle position sensor,
the ECM now uses the VTA signal to detect the completely closed state of
the throttle valve.
A new EGR system which uses a EGR valve position sensor is used.
A communication method of the ECM and the hand±held tester has been
changed from the SAEJ1962 to the ISO 9141±2.
*: Applicable only to Vehicle Equipped with the TRAC System.
