3. Installed condition of coolant temperature sensor.
• Check for looseness or pinching.
Refer to “CYLINDER HEAD” on page 5-26.
4. Defective coolant temperature sensor.
• Check the coolant temperature sensor resistance.
Refer to “CHECKING THE COOLANT TEMPERATURE SENSOR” on page 8-63.
5. Defective wire harness.
• Replace the wire harness.
• Execute the diagnostic mode. (Code 06)
• When engine is cold: Displayed temperature is close to the ambient temperature.
• Submerge the coolant temperature sensor in a container filled with water at 20 °C (68 °F) and
100 °C (212 °F).
• Displayed temperature is close to the 20 °C (68 °F) and 100 °C (212 °F).
Is check result OK?
YES
→ Go to step 4.
NO
a. Reinstall the sensor.
b. Execute the diagnostic mode. (Code 06)
• When engine is cold: Displayed temperature is close to the ambient temperature.
Is check result OK?
YES
→ Go to step 7, and complete the service.
NO
→ Go to step 4.
Coolant temperature sensor resistance
2.645 kΩ ± 5 % at 20 °C (2.645 kΩ ± 5 % at 68
°F)
0.216 kΩ ± 2.5 % at 100 °C (0.216 kΩ ± 2.5 % at
212 °F)
