Fig. 1 Temperature sensor resistance

The diagram is valid for engine coolant temperature sensor G62 and intake
air temperature sensor G72.

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

Examples:

- 30 °C corresponds to a resistance value of 1500 - 2000 Ohms
- 80 °C corresponds to a resistance value of 275 - 375 Ohms
