A/C Refrigerant Temperature Switch

WARNING: This page is about a different car, the 2014 Mitsubishi Outlander. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION: Do not heat more than necessary.

Dip the metal part of the A/C refrigerant temperature switch into engine oil and increase the oil temperature using a gas burner or similar.

When the oil temperature reaches the standard value, check that voltage is supplied between the terminals.

CAUTION:

STANDARD VALUE SPECIFICATION

Item	Temperature
Less than 2 ohms	Slightly below 120° C (248° F)
No continuity	135° C (275° F) or more

NOTE: When the oil temperature is 135° C (275° F) or more and there is no continuity, the resistance will not be 2Ω or lower until the oil temperature reduces to 120° C (248° F) or less.
