75 to 100°C (167 to 212°F): After warming up |
This is the engine coolant temperature.
HINT:
- After warming up the engine, the engine coolant temperature will be 75 to 100°C (167 to 212°F).
- After a long soak, the engine coolant temperature, intake air temperature and ambient air temperature will be approximately equal.
- If the value is -40°C (-40°F), or higher than 135°C (275°F), the sensor circuit is open or shorted.
- Check if the engine overheats if the value indicated is higher than 135°C (275°F).
