4) Coolant Temperature Gauge
Using a needle, it displays the coolant temperature obtained from the engine coolant
temperature sensor. The PTC resistance value of the coolant temperature sensor is transmitted
to the engine ECU and then to the cluster as CAN signal. The angle of guage that can be
varied by coolant temperature is as shown below.
Measurement of coolant temperature sensor resistance
Measure the resistance between the terminal and the ground with an ohmmeter and replace if
the resistance is out of specified range.
Resistance value by coolant temperature:
- When the resistance value by coolant temperature is within the specified range, check
thermostat, water pump, radiator related coolant circuit for normal operation. Also, check the
wiring harnesses and connectors for proper connection (D27DT engine ECU: NO.101, 102 /
D27DTP (power up) engine ECU: A56, A57).
-
The time when the engine coolant temperature reaches the normal temperature (gauge
indicating angle: 0°)
Therefore, the coolant temperature gauge should be used only for reading its movement.
20°C - 2449Ω ± 5 %
50°C - 826Ω ± 5 %
80°C - 321Ω ± 5 %
100°C - 12Ω ± 5 %
depends on the ambient temperature and the vehicle's load.
