→ Fig. 1    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:

• ◆ 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

→ Fig.2    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:

• ◆ 20 °C is in range A and corresponds to a resistance of 2.3...2.6 kω
