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)

77°F (25°C) / 29.7K - 36.3K
185°F (85°C) / 3.3K - 3.7K
