→ Fig. 1    Resistance graph

The diagram is valid for coolant temperature sender (G62) and intake manifold temperature sender (G72).

Scale A shows resistance values for temperature range 0...50 °C and scale B the values for temperature range 50...100 °C.

Examples:

• ◆ 30 °C corresponds to a resistance from 1500...2000 ω
• ◆ 80 °C corresponds to a resistance from 275...375 ω
