Purpose
The ambient temperature sensor detects the ambient temperature.
Function
The ambient temperature sensor converts the detected temperature to an electric signal.
Construction
A thermistor-type ambient temperature sensor has been adopted.
The ambient temperature sensor is installed to the shroud panel on the back side of the front bumper.
Operation
The thermistor changes the resistance according to the surrounding temperature.
The resistance decreases if the temperature increases, and conversely increases if the temperature decreases as shown in the figure.

Service Cautions
Injury/damage Prevention Precautions
Depending on the vehicle, the cooling fan may operate suddenly even when
the ignition is switched to off. Therefore, keep hands and tools away from the
cooling fan even if the cooling fan is not operating to prevent injury to personnel
or damage t ...
Purge Control
Outline
An appropriate amount of evaporative gas is fed into the intake manifold
by the purge solenoid valve operation according to the engine operation conditions.
This ensures driveability and prevents release of evaporative gas into the atmosphere.
The PCM drives the purge so ...
