Acura RL (1996-2004 year). Manual — part 602
Outside Air Temperature Sensor
Replacement
Disconnect the connector from the outside tempera-
ture sensor, then remove the bolt and the outside
air temperature sensor.
6 x 1.0 mm
9.8 N-m (1.0 kgf-m, 7.2 Ibf-ft)

2. Install in the reverse order of removal.
Test
Compare the resistance reading between the No. 1 and No.
2 terminals of the outside air temperature sensor with the
specifications shown in following graph; resistance should
be within specifications.
NOTE: Dip the sensor in ice water, and measure resis-
tance. Then pour hot water on the sensor, and check for
change in resistance.
CAUTION: The sensor uses a thermistor which can be
damaged if high current is applied during testing.
Therefore, use a circuit tester with an output of 1 mA or
less at the 20 k range.

Sunlight Sensor
Replacement
Remove the sunlight or sunlight/automatic lighting
sensor(s) from the dashboard, then disconnect the
connector. Separate the sunlight and automatic light-
ing sensor(s).
CAUTION: Be careful not to damage the sunlight or
sunlight/automatic lighting sensor(s) and the dash-
board.

2. Install in the reverse order of removal.
Test
Turn the ignition switch ON (II). Measure the voltage
between the terminals with the (+) probe on the No. 2
terminal and the (-) probe on the No. 1 terminal with the
2P connector connected. Voltage should be;
3.5 to 3.9 V or more with the sensor out of direct sun-
light.
3.8 to 3.4 V or less with the sensor in direct sunlight.
NOTE: The voltage will not change under the light of a
flashlight or a fluorescent lamp.

Evaporator Temperature
Sensor Power Transistor
Test
Compare the resistance reading between the No. 1 and
No. 2 terminals of the evaporator temperature sensor
with the specifications shown in following graph; resis-
tance should be within specifications.
NOTE: Dip the sensor in ice water, and measure resis-
tance. Then pour hot water on the sensor, and check for
change in resistance.
CAUTION: The sensor uses a thermistor which can be
damaged if high current is applied during testing.
Therefore, use a circuit tester with an output of 1 mA or
less at the 20 k range.

1. Disconnect the 3P connector from the power tran-
sistor.
2. Pull out the No. 2 (ORN) terminal from the connec-
tor.
3. Connect a 1.2 - 3.4 watt bulb as shown, then recon-
nect the 3P connector to the power transistor.
12V 1.2-3.4 W

No. 3 (BLU/RED)
4. Turn the ignition switch ON (II), and check that the
blower motor runs.
CAUTION:
To avoid a loose or disconnected terminal, be careful
not to damage the locking tab when disconnecting
and connecting the terminal.
Insulate the No. 2 (ORN) terminal from the body until
the testing is completed.

Relays
Test
There should be continuity between the No. 1 and No. 3
terminals when power and ground are connected to the
No. 2 and No. 4 terminals, and there should be no conti-
nuity when power is disconnected.

There should be continuity between the No. 4 and No. 5
terminals when power and ground are connected to the
No. 1 and No. 3 terminals, and there should be continu-
ity between the No. 2 and No. 5 terminals when power
is disconnected.
