HEATING / AIR CONDITIONING: AIR CONDITIONING SYSTEM: B1467/67: Rear Air Foot Duct Sensor Circuit on Driver Side

DTC B1467/67 - Rear Air Foot Duct Sensor Circuit on Driver Side

DESCRIPTION

The air duct temperature sensor LH (for driver side) detects the duct temperature and sends the appropriate signals to the air conditioning amplifier assembly.

INSPECTION PROCEDURE

PROCEDURE

1. READ VALUE USING TECHSTREAM (AIR DUCT TEMPERATURE SENSOR LH)
(a) Use the Data List to check if the air duct temperature sensor LH (for driver side) is functioning properly.

Air Conditioner





OK:
The display is as specified in the normal condition.
NG -- CHECK AIR DUCT TEMPERATURE SENSOR LH
OK -- REPLACE AIR CONDITIONING AMPLIFIER ASSEMBLY
2. CHECK AIR DUCT TEMPERATURE SENSOR LH





(a) Remove the air duct temperature sensor LH.
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:





NOTICE:
- Touching the sensor even slightly may change the resistance value. Hold the connector of the sensor.
- When measuring the resistance, the sensor temperature must be the same as the ambient temperature.
HINT: As the temperature increases, the resistance decreases (see the graph).
If the resistance value is not as specified, replace the sensor.

NG -- REPLACE AIR DUCT TEMPERATURE SENSOR LH
OK -- Continue to next step.
3. CHECK HARNESS AND CONNECTOR (AIR CONDITIONING AMPLIFIER - AIR DUCT TEMPERATURE SENSOR)





(a) Disconnect the K21 sensor connector.
(b) Disconnect the E35 amplifier connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:






NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPLACE AIR CONDITIONING AMPLIFIER ASSEMBLY
