Our trusted friends have launched a new website named LEMON, which has newer manuals. It also contains all the CHARM manuals.

LEMON is the spiritual successor to CHARM, I recommend you try it!

Resistance Graph



Resistance Graph

Fig.1 Resistance Graph:





The diagram is valid for 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 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
