Summary
This service bulletin addresses a known non-safety-related condition in certain Model 3 and Model Y vehicles, where the refrigerant pressure/temperature sensors in the heat pump may fault over time.
The correction involves replacing all three refrigerant PIT sensors with new ones, using specific part numbers and tools.
The procedure includes removing the underhood storage unit, recovering the A/C refrigerant, and disconnecting the electrical harness from the sensors.
Caution is advised when removing the sensors to avoid breaking the threads.
The bulletin also provides instructions for installing new washers and lubricating the O-rings and threads of the new sensors.
