apply a thin coat of the same
refrigerant oil used in the A/C compressor. Be sure to use the correct
O-rings for HFC-134a
(R-134a) to avoid leakage.
- Charge the system with the specified amount of R-134a refrigerant.

- Dip the sensor in ice water, and measure the resistance
between terminals No. 1 and No. 2
- Then pour warm water on the sensor, and check for a
change in resistance
- Compare the resistance readings with the specifications
shown in the graph; the resistance should be within the
specifications
- If the resistance is not as specified, replace the evaporator
temperature sensor.
