for the temperature range 0 to 50 °C, the
range B the values for the temperature
range 50 to 100 °C.
Examples:
30 °C corresponds to a resistance of
t
1500 to 2000 Ω
80°C corresponds to a resistance of 275
t
to 375 Ω
If the nominal value is not reached,
–
replace the sender.
If the nominal value is reached, test wiring
from sender to engine control unit as
follows:
Connect the test box -V.A.G 1598/22 - to
