Ignition "ON"
Using the multi-tester, Measure resistance between terminal "1" and "2" of water temperature sensor.
Coolant temperature [℃(℉)] | Resistance (㏀) |
-10(14) | 55.85 |
0(32) | 32.91 |
10(50) | 19.99 |
20(68) | 12.51 |
30(86) | 8.047 |
40(104) | 5.311 |
50(122) | 3.588 |
60(140) | 2.476 |
70(158) | 1.742 |
80(176) | 1.246 |
If the measured resistance is not specification, substitute with a known-good water temperature sensor and check for proper operation.
If the problem is corrected, replace the water temperature sensor.
Negative type thermistor that resistance will rise with lower temperature, and reduce with higher temperature.
Disconnect the negative (-) battery terminal.
Remove the crash pad(refer to BD group-crash pad)
Remove the heater unit(refer to HA group-heater unit)
Loosen the heater core cover mount screw and then heater core cover(A).
Disconnect the water temperature sensor(B) from heater core cover.
Installation is the reverse order of removal.
Take care that wire of water temperature sensor is not to be damaged.
