Signal Waveform
Inspection 1. Turn the ignition switch OFF. 2. Disconnect the HO2S connector. 3. Measure resistance between the HO2S terminals 1 and 2. 4.
Removal 1. Disconnect the negative (-) battery terminal. 2. Remove the crash pad lower panel. (Refer to Body - "Crash Pad") 3. Remove the blind spot detection (BSD) switch (A) after disengaging the mounting clip. Installation 1. Install the crash pad side switch assembly after connecting the connector.
Description An in-car air temperature sensor is located in the crash pad lower panel. The sensor contains a thermistor which measures the temperature of the cabin. The signal determined by the resistance value which changes in accordance with perceived inside temperature, is delivered to the heater control unit and according to this signa
