1986 TOYOTA CAMRY V20 fuel

(e) Tighten the O±ring fittings or the bolted type fittings to
the specified torque.
4. WHEN CONNECTING MANIFOLD GAUGE;
(a) Be sure to connect the charging hose end with a pin
to the compressor charging valve.
(b) The letter ºDº engraved near the compressor service
valve indicates the high pressure side, and ºSº indi-
cates the low pressure side. Pay careful attention
when connecting the hose.
(c) Tighten hose by hand.
(d) To prevent loosening of connected hose, do not apply
drops of compressor oil to the seat of connection.
HINT: After connecting the manifold gauge and the refrig±
erant container (service can), discharge any air in the
hoses.
5. WHEN EVACUATING;
Approx. 15 minutes after removal, check the system for
leaks, then take at least another 15 minutes to make sure
the air is fully removed.
6. WHEN HANDLING REFRIGERANT CONTAINER
(SERVICE CAN);
(a) Must never be heated.
(b) Must be kept below 4

°C (1 04°F).
(c) If warming service can with hot water, be careful that
the valve on top of the service can is never immersed
in the water, as the water may permeate into the refrig-
erant cycle.
(d) Empty service cans must never be re±used.
7. WHEN A/C IS ON AND REFRIGERANT GAS IS
BEING REPLENISHED;
(a) If there is not enough refrigerant gas in the refrigerant
cycle, oil lubrication becomes insufficient and com-
pressor burnout may occur, so take care to avoid this.
(b) If the valve on the high pressure side is opened, refrig-
erant flows in reverse and causes the service can to
rupture, so only open and close the vlave on the low
pressure side.
(c) If the service can is inverted and refrigerant is inserted
in a liquid state, the liquid is compressed and the com-
pressor brakes down, so the refrigerant must be in-
serted in a g¿¿seous state.
(d) Be careful not to insert too much refrigerant gas, as
this causes trouble such as inadequate cooling, poor
fuel economy, engine overheat, etc.
8. WHEN USING GAS±CYLINDER TYPE LEAK
DETECTION INSTRUMENT;
(a) As a naked flame is used, first make sure that there are
no flammable substances nearby before using it.
(b) Be careful, as poisonous gas is produced when
refrigerant gas comes in contact with heat parts.

A140E Automatic Transaxle (ECT)
WHAT IS THE ECT?
ECT means Electronic Controlled Transaxle. The hydraulic control system of the previous automatic
transaxle has been changed, the throttle and governor pressure have been replaced by electronic
signals and a micro computer has been used to give precise control of shift timing and lock±up tim-
ing.
FEATURES OF THE ECT
(a) The shift pattern can be chosen.
In the ECT ECU micro computer used in the A140E, two types of shift pattern, Power and Normal,
are recorded in the memory. By operating the pattern select switch, the driver can select the pre-
ferred shift pattern.
(b) Reduced fuel consumption and reduced shock during shifting is made possible.
Precise control of the shift timing by the ECT ECU, operation of the lock±up clutch from low speeds,
and decreased fuel consumption are made possible. Also, shock during Shifting is reduced.
(e) Self±Diagnostic System
When a malfunction occurs in the electronic control system, the driver is informed of this fact. Also,
there is a Self±Diagnostic System which displays the location of the malfunction when the service
connector is shorted.
(d) Fail±Safe System
A fail±Safe System is included so that, even if a malfunction occurs in the electronic control system,
the vehicle will be able to operate.
CONSTRUCTION AND OPERATION
When the A140E (ECT) is compared with the A140L, the automatic transaxle body has the same
construction and operation, with the exception of the hydraulic control system, as the A140L.
The electronic control system, which controls the shift timing and lock±up timing, has been added.
1. Hydraulic Control System (Comparison with the A140L)
VALVE BODY ± Additions or changes to solenoid valve
In the A140E there are three solenoid valves, the No. 1, the No. 2 and the lock±up solenoid valves.
Shifting occurs according to whether the No. 1 and No. 2 solenoid valves are ON or OFF, and the
lock±up solenoid valve controls the lock±up clutch.
GOVERNOR VALVE ± Removed
With the A140E, the governor valve has been replaced with a speed sensor, so that instead of the
governor pressure, a speed sensor signal is sent to the ECT ECU.
SHIFT CONTROL IN ECT
1. The vehicle speed is sensed by the vehicle speed
sensor, which sends this data to the
ECU in the form of electrical signals.
2. The angle to which the throttle is open is sensed
by the throttle position sensor, which sends this
data to the ECU in the form of electrical signals.
3. The ECT computer determines the shift point on
the basis of these two signals and operates the
solenoid valves in the hydraulic control unit, thus
shifting the transmission.

Fuel Gauge
INSPECTION OF GAUGE
1. INSPECT RECEIVER GAUGE OPERATION
(a) Disconnect the connector from the sender gauge.
(b) Turn the ignition switch ON, check that the receiver
gauge needle moves to EMPTY.
(e) Connect the terminals 3 and 4 on the wire harness
side connector through a 3.4W test bulb, check that
the bulb lights and receiver gauge needle moves to-
wards the full side.
HINT: Because of the silicon oil in the gauge, it will take
a short time for the needle to stabilize.
If operation is not as specified, test the receiver gauge.
Tachometer
INSPECTION OF TACHOMETER
INSPECT TACHOMETER OPERATION (ON±VEHICLE)
(a) Connect a tune±up test tachometer, and start the en-
gine.
NOTICE:
wRemoving the connection of the tachometer will
damage the transistors and diodes inside.
wWhen removing or installing the tachometer, be
careful not to drop or subject it to heavy shocks.
(b) Compare the tester and tachometer indications.
If error is excessive, replace the tachometer.

INSPECTION OF LEVEL WARNING
1. INSPECT WARNING LIGHT OPERATION
(a) Disconnect the connector from the sender gauge.
(b) Connect terminals 1 and 2 on the wire harness side-
connector.
(e) Turn the ignition switch ON, check that the warning
light lights.
If the warning light does not light, test the bulb.
2. INSPECT WARNING SWITCH OPERATION
(a) Apply battery voltage to terminals 1 and 2 through a
3.4W test bulb, check that the bulb lights.
HINT: It will take a short time for the bulb to light.If resistance value is not as specified, replace the receiver
gauge.
3. INSPECT SENDER GAUGE OPERATION
(a) Connect a series of three 1.5V dry cell batterys.
(b) Connect the positive (+) lead from the dry cell batter-
ys to terminal 3 through a 3.4W test bulb and the neg-
ative (±) lead to terminal 4.
(c) Check that the voltage rises between terminals 3 and
4 as the float is moved from the top to bottom posi-
tion. 2. MEASURE RECEIVER GAUGE RESISTANCE
Measure the resistance between terminals.
(d) Measure the resistance between terminals 3 and 4
for each float position.
If operation is not as specified, replace the sender
gauge.

INSPECTION OF GAUGE
1. INSPECT RECEIVER GAUGE OPERATION
(a) Disconnect the connector from the sender gauge.
(b) Turn the ignition switch ON, check that the receiver
gauge needle moves to COOL.
(c) Ground the terminal on the wire harness side con-
nector through a 3.4W test bulb.
(d) Turn the ignition switch ON, check that the bulb lights
and the receiver gauge needle moves to the hot side.
If operation is not as specified, measure the receiver
gauge resistance. (b) Submerge the switch in fuel, check that the bulb goes
out.
If operation is not as specified, replace the sender gauge.
2. MEASURE RECEIVER GAUGE RESISTANCE
Measure the resistance between terminals.
If resistance value is not as specified, replace the re-
