2.With temperature sensing
portion of engine coolant temperature sensor immersed in hot
water, measure the resistance between connector
terminals. Standard value:
14
- 17 kΩ (at -20°C) 2.1
- 2.7 kΩ (at 20°C) [0.26
- 0.36 kΩ (at
80°C)]
3.If the
resistance deviates from the standard value greatly, replace
the sensor.

4.Apply the sealant over the
screw sections on the engine coolant temperature
sensor. Specified
sealant:
LOCTITE 262, Three bond 1324N or
equivalent
5.With the special
tool engine coolant temperature sensor wrench (MB992042)
