1834. WATER TEMPERATURE GAUGE MALFUNCTION
CIRCUIT DIAGRAM
(a) Get the value of water temperature with the diagnosis tester
1Connect the diagnosis tester to the diagnosis interface
2Turn the ignition switch to ON
3Read the value of engine water temperature displayed on the diagnosis tester
Standard: The same with the actual engine coolant temperature.
Result and solution:
If it is normal, the water temperature gauge has no malfunction
If abnormal, Inspect the combination meter assembly
(b) Inspect the combination meter assembly
