• Never subject the coolant temperature sen-
sor to strong shocks. If the coolant temper-
ature sensor is dropped, replace it.
2. Check:
• Coolant temperature sensor resistance
Out of specification → Replace.

b. Immerse the coolant temperature sensor "1"
in a container filled with coolant "2".
TIP
Make sure the coolant temperature sensor ter-
minals do not get wet.
c. Place a thermometer "3" in the coolant.
d. Heat the coolant or let it cool down to the
specified temperatures.
e. Measure the coolant temperature sensor re-
sistance.
