Resistance graph
The diagram is valid for the
coolant temperature sender
G62
and the
intake air temperature sender
G42
.
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 kΩ.
