INSPECTION
1. INSPECT FUEL RECEIVER GAUGE OPERATION
(a) Disconnect the connector from the ECM.
(b) Turn the ignition switch ON, check that the receiver gauge
needle indicates EMPTY.
(c) Connect terminals 2 on the wire harness side connector
through a 3.4±W test bulb.
(d) Turn the ignition switch ON, check that the bulb lights up
and the receiver gauge needle moves towards the full
side.
HINT:
Because of the silicon oil in the gauge, it will take a short time
for needle to stabilize.
If operation is not as specified, inspect the receiver gauge resis-
tance.
2. INSPECT FUEL RECEIVER GAUGE RESISTANCE
Measure the resistance between terminals.
Tester connectionResistance (W)
A ± BApprox. 270.1
A ± CApprox. 141.3
B ± CApprox. 128.8
If resistance value is not as specified, replace the receiver
gauge.
3. INSPECT FUEL SENDER GAUGE RESISTANCE
(See page SF±36)
4. INSPECT FUEL LEVEL WARNING LIGHT
(a) Disconnect the connector from the sender gauge.
(b) Connect terminals 8 on the wire harness side connector.
(c) Turn the ignition switch ON, check that the warning light
lights up.
If the warning light does not light up, test the bulb or inspect wire
harness.

6. INSPECT ENGINE COOLANT TEMPERATURE RE-
CEIVER GAUGE OPERATION
(a) Disconnect the connector from the sender gauge.
(b) Turn the ignition switch ON and check that the receiver
gauge needle indicates COOL.
(c) Ground terminal on the wire harness side connector
through a 3.4±W test bulb.
(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.
7. INSPECT ENGINE COOLANT TEMPERATURE RE-
CEIVER GAUGE RESISTANCE
Measure the resistance between terminals.
Tester connectionResistance (W) *
A ± BApprox. 175.7
A ± CApprox. 54.0
B ± CApprox. 229.7
*: 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.

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.

BODY ELECTRICAL SYSTEM
PRECAUTION
Take care to observe the following precautions when performing inspections or removal and replacement
of body electrical related parts.
1. HEADLIGHT SYSTEM

Halogen bulbs have pressurized gas inside and require special handling. They can burst if scratched
or dropped. Hold a bulb only by its plastic or metal case. Don't touch the glass part of a bulb with bare
hands.
2. SRS (SUPPLEMENTAL RESTRAINT SYSTEM)

The CAMRY is equipped with an SRS (Supplemental Restraint System) such as the driver airbag and
front passenger airbag. Failure to carry out service operation in the correct sequence could cause the
SRS to unexpectedly deploy during servicing, possibly leading to a serious accident. Before servicing
(including removal or installation of parts, inspection or replacement), be sure to read the precaution-
ary notices in the RS section.
3. AUDIO SYSTEM

If the negative (±) terminal cable is disconnected from the battery, the preset AM, FM 1 and FM 2 sta-
tions stored in memory are erased, so make sure to note the stations and reset them after the negative
(±) terminal cable is reconnected to the battery.

If the negative (±) terminal cable is disconnected from the battery, the ºANTI±THEFT SYSTEMº will
operate when the cable is reconnected, but the radio, tape player and CD player will not operate. Be
sure to input the correct ID number so that the radio, tape player and CD player can be operated again.
4. MOBILE COMMUNICATION SYSTEM

If the vehicle is equipped with a mobile communication system, refer to precautions in the IN section.
