- How the car detects it
- Transmission fluid pressure sensor/switch H is the last of up to eight pressure inputs (A to H) in SAE J2012; the letter is the maker's choice. Documented uses are rare: Mitsubishi sets P084A on its Jatco CVT8 (F1CJC/W1CJC) and Ford P084B on the 2020–23 Explorer 3.3 full hybrid. For P084E no maker is documented. It reports short dropouts or jumps of the H signal without a lasting low or high, typically from a loose contact or corrosion at the gearbox connector.
