Sensor Range Charts

COOLANT TEMPERATURE (ECT) SENSOR RESISTANCE TEST (1)

Temperature - °F (°C) Ohms
-4 (-20) 15,000-18,000
68 (20) 2000-3000
176 (80) 300-500
(1) Measure resistance across sensor terminals.
INTAKE AIR TEMPERATURE (IAT) SENSOR RESISTANCE TEST (1)

Temperature - °F (°C) Ohms
-4 (-20) 15,000-18,000
68 (20) 2000-3000
