Testing the Hydraulic Fluid Temperature Sender (continued)

4. Put the sensing end of the sender in a container of oil with a thermometer
and slowly heat the oil.
Note: Prior to taking resistance readings with a digital multimeter, short the
meter test leads together. The meter will display a small resistance value
(usually 0.5 ohms or less). This resistance is due to the internal resistance
of the meter and test leads. Subtract this value from the measured value
of the component you are testing.
5. Check resistance of the sender with a multimeter (ohms setting) as the oil
temperature increases.
A. The meter should indicate from 11.6 to 13.5 kilohms at 20C (68F).
B. The meter should indicate 2.3 to 2.5 kilohms at 60C (140F).
C. The meter should indicate 605 to 669 ohms at 100C (212F).
6. If the sender tests correctly and a circuit problem still exists, check the wire
harnesses; refer to
7. Use a new O-ring and install the sender in the hydraulic tank. Tighten the
sender to 16 N∙m (12 ft-lb).
8. Connect the sender to the frame wire harness.
9. Fill hydraulic system to the proper level.
