System
Outline
Air-fuel Ratio Sensor and
Oxygen Sensor Heater
ControlMaintains the temperature of the air-fuel ratio sensor or oxygen sensor at an
appropriate level to increase accuracy of detection of the oxygen
concentration in the exhaust gas.
Evaporative Emission
Control
[See page EG-131]
The ECM controls the purge flow of evaporative emission (HC) in the
canister in accordance with engine conditions.
Approximately five hours after the ignition switch has been turned OFF,
the ECM operates the canister pump module to detect any evaporative
emission leakage occurring in the EVAP (evaporative emission) control
system through changes in the EVAP control system pressure.
Engine ImmobilizerProhibits fuel delivery and ignition if an attempt is made to start the engine
with an invalid ignition key.
Diagnosis
[See page EG-132]When the ECM detects a malfunction, the ECM diagnoses and memorizes
the failed section.
Fail-safe
[See page EG-133]When the ECM detects a malfunction, the ECM stops or controls the engine
according to the data already stored in the memory.
