In Dynamic Chamber

PURPOSE
Detects temperature of intake air inside dynamic chamber and signals PCME to compensate air/fuel mixture as required.

LOCATION
Right front corner of dynamic chamber.

OPERATION
Sensor is a negative temperature coefficient thermistor; as temperature increases, resistance decreases. Cold air is more dense than warm air. The PCME measures sensor resistance, calculates incoming air temperature, and uses this information to regulate fuel injection quantity and ignition timing.

TEMPERATURE / RESISTANCE (K OHMS)

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