Camry Sedan L4-2.4L (2AZ-FE) (2003)
Coolant Temperature Sensor/Switch (For Computer): Testing and Inspection
E.F.I. ENGINE COOLANT TEMPERATURE SENSOR
Resistance inspection.
Using an ohmmeter, measure the resistance between terminal 1 and 2.
Resistance:
Approx. 20 °C (68 °F) 2.32 - 2.59 KOhm
Approx. 80 °C (176 °F) 0.31 - 0.326 KOhm
NOTE: In case of checking the water temperature sensor in the water, be careful not to allow water to go into the terminals, and after checking, wipe
out the sensor.
