Check ECTS resistance

WARNING: This page is about a different variant/trim than selected.
  1. IG "OFF". Disconnect ECTS connector.
  2. Measure resistance between signal and ground terminals of ECTS connector after checking out the temperature of ECTS with GDS (Component Side)

    [Engine Coolant Temperature Sensor] 

    Temp. (°C) Resistance (kΩ) Temp. (°C) Resistance (kΩ)
    -40°C (-40°F) 48.14 40°C (104°F) 1.15
    -20°C (-4°F) 14.13 ~ 16.83 60°C (140°F) 0.59
    0°C (32°F) 5.79 80°C (176°F) 0.32
    20°C (68°F) 2.31 ~ 2.59    
  3. Is the measured resistance within specification?

    YES 

    • Clear DTC and Test-drive under the Enable Conditions. After the road test, if this DTC is set, recheck resistance. If not, it is intermittent fault. go to "VERIFICATION OF VEHICLE REPAIR ".

    NO 

    • Substitute with a known - good ECTS and check for proper operation. If the problem is corrected, Go to "Verification of Vehicle Repair" procedure.
