Fig. 1 Resistance graph

The diagram applies to Engine Coolant Temperature (ECT) sensor -G62- and Intake Air Temperature IAT) sensor -G72-.

Scale A shows resistance values for temperature range 0° - 50 °C (32 - 122 °F) and scale B shows the values for temperature range 50° - 100 °C (122 - 212 °F).

Examples:
- 30 °C (86 °F) corresponds to a resistance from 1500-2000 Ohms
- 80 °C (176 °F) corresponds to a resistance from 275-375 Ohms
