E1

Linear air-fuel
ratio sensor

Engine: warming
up (Air/fuel
mixture is made
leaner when
decelerating and
is made richer
when revving)

When the
engine is
running at
4,000 r/min,
decelerate
suddenly.

→ 2.0 V or

less (After

seconds have
elapsed)

air-fuel ratio
sensor signal is
used to check
the air/fuel
mixture ratio,
and control
condition is also
checked by the
ECM.)
