WIRING DIAGRAM
INSPECTION PROCEDURE
| 1.READ VALUE USING INTELLIGENT TESTER (AIR DUCT TEMPERATURE SENSOR) |
Use the Data List to check if the air duct temperature sensor LH*1 or RH*2 (for driver side) is functioning properly.
| Tester Display | Measurement Item/Range | Normal Condition | Diagnostic Note |
| Foot Duct Sensor (Rear D) | Min.: -12.7°C (9.14°F) Max.: 76.55°C (169.79°F) |
Actual air duct temperature sensor (for driver side) displayed | Open in the circuit: -12.7°C (9.14°F) Short in the circuit: 76.55°C (169.79°F) |
- HINT:
- *1: for LHD
- *2: for RHD
- OK:
- The display is as specified in the normal condition.

| 2.CHECK AIR DUCT TEMPERATURE SENSOR |
for LHD
Remove the air duct temperature sensor LH ().
for RHD
Remove the air duct temperature sensor RH ().
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection Condition Specified Condition 1 (+) - 2 (-) at 10°C (50°F) 9.4 to 10.5 kΩ at 15°C (59°F) 7.5 to 8.3 kΩ at 20°C (68°F) 6.0 to 6.5 kΩ at 25°C (77°F) 4.5 to 5.2 kΩ at 30°C (86°F) 3.8 to 4.2 kΩ at 35°C (95°F) 3.1 to 3.4 kΩ at 40°C (104°F) 2.5 to 2.8 kΩ at 45°C (113°F) 2.0 to 2.3 kΩ at 50°C (122°F) 1.6 to 2.0 kΩ at 55°C (131°F) 1.3 to 1.6 kΩ at 60°C (140°F) 1.1 to 1.4 kΩ
- NOTICE:
- HINT:
- As the temperature increases, the resistance decreases (see the graph).
- If the resistance value is not as specified, replace the sensor.

| 3.CHECK HARNESS AND CONNECTOR (AIR CONDITIONING AMPLIFIER - AIR DUCT TEMPERATURE SENSOR) |
for LHD
Disconnect the K21 sensor connector.
Disconnect the E35 amplifier connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection Condition Specified Condition E35-25 (TR3) - K21-1 (+) Always Below 1 Ω E35-34 (SGND) - K21-2 (-) E35-25 (TR3) - Body ground Always 10 kΩ or higher E35-34 (SGND) - Body ground
for RHD
Disconnect the L12 sensor connector.
Disconnect the E35 amplifier connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection Condition Specified Condition E35-26 (TR4) - L12-1 (+) Always Below 1 Ω E35-12 (SG-9) - L12-2 (-) E35-26 (TR4) - Body ground Always 10 kΩ or higher E35-12 (SG-9) - Body ground
