1986 TOYOTA SUPRA key

(b) Hold the tensioner with both hands and push the push rod
strongly against the floor or wall to check that it doesn't move.
If the push rod moves, replace the tensioner.
(c) Measure the protrusion of the push rod from the housing end.
Protrusion:
8.0±8.8 mm (0.315±0.346 in.)
If the protrusion is not as specified, replace the tensioner.
5. 2JZ±GTE M/T:
INSPECT DRIVE BELT TENSION DAMPER
Compress and extend the tension damper rod and check that
there is no abnormal resistance or unusual operation
sounds.
If there is any abnormality, replace the tension damper with
a new one.
NOTICE: When discarding the tension damper, use the follow-
ing procedure.
wFully extend the damper rod.
wUsing a drill, make a hole in the cylinder as shown to
release the gas inside.
CAUTION: The gas coming out is harmless, but be careful of
the chips which may fly up when drilling.

1. NORMALLY
OPENOpens and
closes circuits,
thereby
stopping (1) or
allowing (2)
current flow.
RESISTOR
An electrical component with a
fixed resistance, placed in a circuit
to reduce voltage to a specific
value.
RESISTOR, TAPPED
A resistor which supplies two or
more different non adjustable
resistance values.
SENSOR (Thermistor)
A resistor which varies its
resistance with temperature.
SHORT PIN
Used to provide an unbroken
connection within a junction block.
SOLENOID
An electromagnetic coil which
forms a magnetic field when
current flows, to move a plunger,
etc.SWITCH, DOUBLE THROW
A switch which continuously
passes current through one set
of contacts or the other.
SWITCH,
IGNITION
A key operated switch with
several positions which allows
various circuits, particularly the
primary ignition circuit, to
become operational.
Wires are always
drawn as straight lines
on wiring diagrams.
Crossed wires (1)
without a black dot at
the junction are not
joined; crossed wires
(2) with a black dot or
octagonal (
) mark at
the junction are spliced
(joined) connections. RELAY, DOUBLE THROW
A relay which passes current
through one set of contacts or the
other.
SENSOR, ANALOG SPEED
Uses magnetic impulses to open
and close a switch to create a
signal for activation of other
components.TRANSISTOR
A solidstate device typically used
as an electronic relay; stops or
passes current depending on the
voltage applied at ªbase.º SWITCH, WIPER PARK
Automatically returns wipers to
the stop position when the wiper
switch is turned off. SWITCH, MANUAL SPEAKER
An electromechanical device
which creates sound waves from
current flow.
2. NORMALLY
CLOSED
RESISTOR, VARIABLE or
RHEOSTAT
A controllable resistor with a
variable rate of resistance.
Also called a potentiometer or
rheostat. 2. NORMALLY
OPEN RELAY
1. NORMALLY
CLOSEDBasically, an electrically
operated switch which may
be normally closed (1) or
open (2).
Current flow through a
small coil creates a
magnetic field which either
opens or closes an
attached switch.
