ENGINE COOLANT TEMPERATURE SENSOR CHECK


caution Be careful not to touch the connector (resin section) with the tool when removing and installing.

1.Remove the engine coolant temperature sensor.

2.With temperature sensing portion of engine coolant temperature sensor immersed in water, check resistance.
Standard value:
    14 - 17 kΩ (at -20°C)
    5.1 - 6.5 kΩ (at 0°C)
    2.1 - 2.7 kΩ (at 20°C)
    0.9 - 1.3 kΩ (at 40°C)
    0.48 - 0.68 kΩ (at 60°C)
    0.26 - 0.36 kΩ (at 80°C)
3.If the resistance deviates from the standard value greatly, replace the sensor.
4.Remove any sealant that may be remaining an the engine coolant temperature sensor or the threaded hole in the cylinder head.

5.Apply sealant to threaded portion.
Specified sealant:
    LOCTITE 262 or equivalent
6.Install the engine coolant temperature sensor and tighten it to the specified torque.
Tightening torque: 29 ± 10 N·m
