Resistance values for coolant temperature sender -G62-
The diagram is divided into two temperature ranges:
A - From 0...50 °C
B - From 50...105 °C
Examples:
t  30 ºC is in range A and corresponds to a resistance of 1.5...2.0 kΩ
t  80 ºC is in range B and corresponds to a resistance of 275...375 Ω

Resistance values for intake air temperature sender -G42-
The diagram is divided into two temperature ranges:
A - From 0...50 °C
B - From 50...105 °C
Examples:
t  20 ºC is in range A and corresponds to a resistance of 2.3...2.6 kΩ
t  80 ºC is in range B and corresponds to a resistance of 290...330 Ω

t  For this reason the use of a power tool can only be authorized when:
t  The power tool maximum speed is 200 rpm.
t  The tightening torque is set to a maximum of 3 Nm.
