Resistance graph

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

The diagram is divided into two temperature ranges:

A -
From 0...50 °C
B -
From 50...105 °C

Examples:

30 °C is in range A and corresponds to a resistance of 1.5...2.0 kω
80 °C is in range B and corresponds to a resistance of 275...375 ω
