Engine
Gasoline Engine Control System Diagnosis
The engine ECU possesses an OBD (On-Board Diagnostic) function which constantly monitors each sensor and actuator. If it detects a malfunction, the malfunction is recorded as a DTC (Diagnostic Trouble Read more Gasoline Engine Control System Diagnosis
Gasoline Engine Air Intake Control System
The air intake control system is divided into two air cleaner inlets, and one of these inlets is provided with a valve, which is opened and closed to attain suitable air intake efficiency in accordance Read more Gasoline Engine Air Intake Control System
Evaporative Emission Control System
The evaporative emission control system prevents evaporated fuel from the fuel tank from being released into the atmosphere by having the evaporative emissions be temporarily absorbed by a charcoal canister. Read more Evaporative Emission Control System
AI (Air Injection) Control System/AS (Air Suction) Control System
The AI control system/AS control system is a system that feeds air into the exhaust manifold to recombust the uncombusted gas in the exhaust to lower HC and CO emissions. The difference between these two Read more AI (Air Injection) Control System/AS (Air Suction) Control System
ACIS (Acoustic Control Induction System)
The ACIS (Acoustic Control Induction System) changes the effective length of the intake manifold to increase power over a wide range from low speed to high speed. This system uses an intake air control Read more ACIS (Acoustic Control Induction System)
Oxygen Sensor/Air Fuel Ratio Sensor Heater Control System
The detection capability of the oxygen sensor and A/F (air-fuel) ratio sensor decline at low temperatures (under 400
VVTL-i (Variable Valve Timing and Lift-intelligent)
The VVTL-i system is based on the VVT-i system and employs a cam changeover mechanism to change the amount of the intake and exhaust valve lift. This makes it possible to attain high power without affecting Read more VVTL-i (Variable Valve Timing and Lift-intelligent)
VT-i (Variable Valve Timing-intelligent)
Generally, the valve timing is fixed, but the VVT-i system uses the hydraulic pressure to shift the intake camshaft rotation and vary the valve timing. This makes it possible to increase output, improve Read more VT-i (Variable Valve Timing-intelligent)
Electronic Throttle Control System-intelligent Other Controls
The ETCS-i controls the throttle valve opening angle to the optimum amount in accordance with the amount which the accelerator pedal is depressed.
