Check ECT Sensor Resistance
- Ignition switch is turned "OFF". Disconnect ECT Sensor connector.
- Measure resistance between signal and ground terminals of ECT Sensor connector after checking out the temperature of ECT Sensor with GDS. (Component Side)
Specification:
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 - 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 ECT Sensor and check for proper operation. If the problem is corrected, Go to "VERIFICATION OF VEHICLE REPAIR " procedure.
