Fig. 6 Resistance values







The diagram applies to the Engine Coolant Temperature (ECT) sensor -G62- and for the Intake Air Temperature (IAT) sensor -G42-.

The diagram is divided into two temperature ranges:

A - from 0-50 °C
B - from 50-105 °C

Examples of how to read the diagram:
- 30 °C is in range A and corresponds to a resistance of 1.5-2.0 k Ohms
- 80 °C is in range B and corresponds to a resistance of 275-375 Ohms
