Refrigerant Charge (with C69)
Abrupt refrigerant loss due to a large leak, hose rupture, collision, or pressure relief valve opening. Conditions that
allow the refrigerant to seep or bleed off over time do not cause this oil loss. Upon replacement of a component that
caused a large refrigerant loss, also add the required amount of oil for the particular component.
If more than the specified amount of PAG oil was drained from a component, add the equal amount of oil drained.

The Tech 2 will display sensor value as a voltage. This gives the approximate voltage expected at different ambient
temperatures as well as what should be read with an ohmmeter connected to the sensor. Since this is raw data any
heat from underhood that changes ambient temp around the sensor might skew the reading, so let the engine
compartment cool.
