Automatic Transaxle

Intake Air Thermosensor:

PURPOSE
Measure temperature of intake air and provide PCME with signal used in regulating fuel injection quantity, idle speed, and ignition timing.

LOCATION
Top air cleaner housing.

OPERATION
Thermosensor is a negative temperature coefficient thermistor. This means as temperature increases, resistance decreases. Cold air is more dense than warm air. PCME measures thermosensor resistance via a reference voltage to calculate intake air temperature.

TEMPERATURE / RESISTANCE (K OHMS)

68°F (20°C) / 35.5K - 39.2K
140°F (60°C) / 7.2K - 7.9K
176°F (80°C) / 1.1K - 1.3K
