An R-134a thermal expansion valve system contains the proper refrigerant charge. During a system perfor- mance test, the low-side gauge reading is 40 psig and the high-side gauge reading is 140 psig with an ambi- ent air temperature of 878F (30.558C). Which of the fol- lowing is the most likely cause of these results
