Coolant Temperature Sensor/Switch (For Computer)

Resistance graph





The graph is valid for the Engine Coolant Temperature (ECT) sensor -G62- and
Intake Air Temperature (IAT) sensor -G42-.

The graph is divided into two temperature ranges:
- Range A: 0-50 °C (32-122 °F)
- Range B: 50-105° C (122-221° F)

Examples:
- 30 °C (86 °F) is in range A and corresponds to a resistance of 1.5-2.0 k Ohms
- 80 °C (176 °F) is in range B and corresponds to a resistance of 275-375 Ohms
