BASIC MULTIPORT FUELINJECTION
SYSTEM

The amount offuel injected fromthefuel injector
is determined bythe ECM. TheECM controls the
length oftime thevalve remains open(injection
pulse duration). Theamount offuel injected isa
program valueinthe ECM memory. Theprogram
value ispreset byengine operating conditions.
These conditions aredetermined byinput signals
(for engine speedandintake air)from boththe
camshaft positionsensorandthemass airflow
sensor.

INCREASE/DECREASE COMPENSATION

In addition, theamount offuel injected iscom-
pensated toimprove engineperformance under
various operating conditions aslisted below.

<

• During warm-up
• When starting theengine
• During acceleration
• Hot-engine operation
• When selector leverischanged from"N"to

models only)
• High-load, high-speed operation

<

• During deceleration

If the engine speedisabove 2,500rpmwith noload (for
example, inneutral andengine speedover2,500 rpm)fuelwill
be cut offafter some time.Theexact timewhen thefuel iscut
off varies basedonengine speed.
Fuel cutwill operate untiltheengine speedreaches 2,000rpm,
then fuelcutiscancelled.

This function isdifferent thandeceleration controllistedunder
