      Condition

      Specified Condition

      1 - 2

      -40°C (-40°F)

      73508 to 78016 Ω

      -20°C (-4°F)

      21293 to 22417 Ω

      0°C (32°F)

      7188 to 7515 Ω

      20°C (68°F)

      2758 to 2866 Ω

      40°C (104°F)

      1179 to 1219 Ω

      60°C (140°F)

      552 to 568 Ω

      80°C (176°F)

      280 to 286 Ω

      100°C (212°F)

      151 to 154 Ω

      120°C (248°F)

      86 to 89 Ω

      Note:

      If checking the engine coolant temperature sensor in water, be careful not to allow water to contact the terminals. After checking, wipe the water off the engine coolant temperature sensor.

      If the result is not as specified, replace the engine coolant temperature sensor.
