P084FPark/Neutral Switch Output Circuit
- Generic OBD-II code · Powertrain
- How the car detects it
- P084F concerns an output: a gearbox, hybrid or selector module passes the park/neutral status as a switched signal to other modules, for example for start release. The module watches its own driver for open circuits and shorts. Stellantis names the code for the 2019 Pacifica plug-in hybrid, where it came with a software fault that drained the 12 V battery; a hybrid control update fixes it. Saab's gearbox module reports the same kind of P/N output to the engine module under P081A/P081B. Strategy and MIL status are not published.
