Engine Temperature Sensor: Service and Repair

Fig. 1 Sensor resistance graph
- Diagram applies to both Engine Coolant Temperature sensor -G62- and Intake Air Temperature sensor -G72-
- Scale A shows resistance values for temperature range 0 to 50 °C, scale B shows values for temp range 50 to 100 °C.

Examples:
- 30 °C corresponds to a resistance between 1500 and 2000 Ohms
- 80 °C corresponds to a resistance between 275 and 375 Ohms
