3. INSPECT DIESEL ENGINE ENGINE COOLANT
TEMPERATURE SENSOR
(a) Resistance inspection.
(1) Using an ohmmeter, measure the resistance be-
tween each terminal.
Resistance:
Approx. 20C (68F) 2.32 to 2.59 k
Approx. 80C (176F) 0.310 to 0.326 k
NOTICE:
In case of checking the water temperature sensor in the wa-
ter, be careful not to allow water to go into the terminals,
and after checking, wipe out the sensor.
4. INSPECT INJECTION OR SUPPLY PUMP ASSY
(a) Resistance inspection. (Fuel temperature sensor)
(1) Using an ohmmeter, measure the resistance be-
tween each terminal.
Resistance:
