ECI SYSTEM COMPONENTS
Nl4BBCAm-
AIR FLOW SENSOR (AFS)
The OAFS meaSures the intake air volume. It makes use of.-
Karman vortex to detect the air flow rate and-sends it to the-_
ECU as the intake air volume signal.
The ECU uses this intake airvolume signal to decide the basic
fuel injection duration. -
BAROMETRIC PRESSURE SENSOR
N14BBDA
The barometncpressure sensor Installed on the AI-S senses_
the barometric pressure and converts It rnto a voltage which
IS-
smt to the ECU.
-
The ECU uses this sional to%ompute the altrtude at whtch the
vehicle IS runnrna Andy corrects accordrngly the air-fuel ratro to I
the optimum and also ccZerects the rgnrtron timing, thus
tmprovrng driveability at high altitude.
INTAKE AIR TEMPERATURE SENSOR
N14BBEA
The intake air temperature sensor, located at the_-illustrated
position on AFS, is a resistor-based sensor for detecting the-
intake air temperature.
According to the intake air temperature information from the
sensor, the ECU provides necessary fuel injection amountt
control.
ENGINE COOLANT TEMPERATURE SENSOR
NlQBBAA
The engine co&ant temperature sensor installed in the engine.-
coolant passage of the intake manifold is a resistor-based-,
sensor. The ECU judges engine warm-up state by the sensor
output voltage-and provides optimum fuel enrichment when I
the engine is cold.
