Fig. 1 Resistance values


NOTE: The chart applies to Engine Coolant Temperature sensor G62 and Intake Air Temperature sensor G42.


The chart is divided into two temperature ranges:
A - from 0 to 50 °C
B - from 50 to 105 °C

Examples:
- 30 °C is in range A and corresponds to a resistance of 1.5 to 2.0 Kilo Ohms
- 80 °C is in range B and corresponds to a resistance of 275 to 375 Ohms
