Form No. F1A3-20-06C
Symbol Meaning Symbol Meaning
Relay (2)
Normally closed
•
Current flowing through coil produces electromagnetic force causing contact to close.
Sensor (1)
•
Detects characteristics such as intake
manifold vacuum and airflow amount
according to resistance variation. Solenoid
•
Current flowing through coil generates
electromagnetic force to operate
plungers.
Sensor (2)
•
Detects resistance variation according
to operation of other parts. Diode
•
Known as a semiconductor rectifier,
the diode allows current flow in one
direction only.
Sensor (3)
•
A resistor whose resistance variation
according to temperature variation.
•
When temperature increases,
resistance decreases.
Sensor (4)
•
Detects pulse signals from rotating
object. Light-emitting
diode
(LED)
•
A diode that lights when current flows.
•
Unlike ordinary bulbs, the diode does
not generate heat when lit.
Sensor (5)
•
Generates potential difference when
tension or pressure is applied.
Capacitor
•
Component that temporarily stores
electrical charge. Reference diode
(Zener diode)
•
Allows current to flow in one direction
up to a certain voltage; allows current
to flow in the other direction once that
voltage is exceeded.
Symbol Meaning
Extent of the change in the wiring position (1)
•
The wiring position can be exchanged freely within the
connector.
Extent of the change in the wiring position (2)
•
The wiring position can be exchanged according to the
following combinations only.
Between A and B, Between C and D, Between E and F
Extent of the change in the wiring position (3)
•
The wiring position can be exchanged according to the
following combinations only.
Between 1, 2, 4 and 7.
•
The wiring positions may be indicated by numbers for some
connectors.
