(d) Turn the ignition switch ON, and check that the bulb lights
up and the receiver gauge needle moves to the hot side.
If operation is as specified, replace the sender gauge.
Then, recheck the system.
If operation is not as specified, measure the receiver gauge re-
sistance.

*: This circuit includes the diode.
HINT:
Connect the test leads so that the current from the ohmmeter
can flow according to the above order.
If resistance value is not as specified, replace the receiver
gauge.
11. INSPECT ENGINE COOLANT TEMPERATURE SEND-
ER GAUGE RESISTANCE
Measure the resistance between the terminal and gauge body.

If resistance value is not as specified, replace the engine cool-
ant temperature sender gauge.
12. INSPECT LOW OIL PRESSURE WARNING LIGHT
(a) Disconnect the connector from the warning switch and
ground terminal on the wire harness side connector.
(b) Turn the ignition switch ON and check that the warning
light lights up.
If the warning light does not light up, test the bulb.

REMOVAL
CAUTION:

Store in a cool place, avoiding direct sunlight, high
temperature and dust.

The moulding is made of polyvinyl chloride. Do not al-
low this material to come in contact with thinner or
other solvents, open flame or boiling water.

The storage time for the moulding and adhesive is
limited to about 9 months.
1. REMOVE ENDS OF MOULDING
Using a scraper, pry the moulding loose about 30 mm (1.18 in.)
form each end.
HINT:
Tape the scraper tip before using.
2. REMOVE MOULDING AND ADHESIVE
(a) Pull off the moulding by cutting the adhesive with a knife.
(b) Scrape off adhesive from the body with sandpaper cutter.
NOTICE:

Remember that 30 ± 80 mm (1.18 ± 3.15 in.) of the ends
of the moulding are glued tightly with a strong adhe-
sive.

Do not reuse moulding.

8. INSPECT ENGINE COOLANT TEMPERATURE SEND-
ER GAUGE RESISTANCE
Connect the wire harness as shown in the illustration, and ad-
just the ammeter pointer to indicate º0º using the slide rheostat,
then read the rheostat indication.
Temperature °C (°F)Resistance (W)
50 (122.0)160 ± 240
120 (248.0)17.1 ± 21.2
If resistance value is not as specified, replace the engine cool-
ant temperature sender gauge.
9. INSPECT LOW OIL PRESSURE WARNING LIGHT
(a) Disconnect the connector from the warning switch and
ground terminal on the wire harness side connector.
(b) Turn the ignition switch ON and check that the warning
light lights up.
If the warning light does not light up, test the bulb.
10. INSPECT LOW OIL PRESSURE SWITCH
(a) Disconnect the connector from the switch.
(b) Check that continuity exists between terminal and ground
with the engine stopped.
(c) Check that no continuity exists between terminal and
ground with the engine running.
HINT:
Oil pressure should be over 24.5 kPa (0.25 kgf/cm
2, 3.55 psi).
If operation is not as specified, replace the switch.

7. HYDRAULIC TEST
Measure the line pressure.
NOTICE:

Do the test at normal operation fluid temperature 50 ± 80 °C (122 ± 176 °F).

The line pressure test should always be carried out in pairs. One technician should observe
the conditions of wheels or wheel stoppers outside the vehicle while the other is doing the test.

Be careful to prevent SST's hose from interfering with the exhaust pipe.
(1) Warm up the ATF.
(2) Remove the test plug on the transaxle case front left side and connect SST.
(See page AX±17 for the location to connect SST)
SST 09992±00095 (09992±00231, 09992±00271)
(3) Fully apply the parking brake and chock the 4 wheels.
(4) Connect an OBD II scan tool or TOYOTA hand±held tester to DLC3.
(5) Start the engine and check idling speed.
(6) Keep your left foot pressing firmly on the brake pedal and shift into D position.
(7) Measure the line pressure when the engine is idling.
(8) Depress the accelerator pedal all the way down. Quickly read the highest line pressure when
engine speed reaches stall speed.
(9) In the same manner, do the test in R position.
Specified line pressure:
