Exhaust Manifold
Purpose, Function
By lengthening the exhaust passage, the transmission of exhaust pressure
waves to other cylinders can be delayed, and the amount of gas exhausted from
a cylinder and for ...
Exhaust System
Purpose, Outline
A 4-2-1 exhaust system has been adopted which reduces residual gas in the
cylinders using the scavenging effect and contributes to a high compression
ratio.

Mass Air Flow (MAF) Sensor/Intake Air Temperature (Iat) Sensor No.1 Removal/Installation
NOTE:
Because the IAT sensor No.1 is integrated in the MAF sensor, replacing the
IAT sensor No.1 includes replacement of the MAF sensor/IAT sensor No.1.
1. Disconnect the negative battery cable..
2. Disconnect the MAF sensor/IAT sensor No.1 connector.
3. Remove the MAF sensor/IA ...
Cooling System Cap
Purpose, Function
The cooling system cap maintains appropriate pressure in the engine coolant
passage. In addition, cooling efficiency has been improved by increasing the
engine coolant boiling point.
Construction
The cooling system cap is installed to the upper part of the ...
Cruise Control System
Outline
Enables driving at a constant speed by setting the vehicle speed with the
cruise control switch instead of operating the accelerator pedal.
The PCM controls the throttle valve actuator to maintain the vehicle at a
constant speed.
