With shift-by-wire or park-by-wire, P, R, N and D are requested electrically (buttons, rotary selector, automatic park on shutdown) and an actuator moves the selector shaft or the park pawl; the module compares the requested with the range actually reached. P07E4 means park is not reached or not held within the allowed time. GM gives thresholds: 2 s in 2018 tables and the ICCM of its electronic range selector (2000 ms), 6–10 s in later tables, type B with the MIL after two trips; a 2018 bulletin for LaCrosse and XT5 blames a misaligned coupling of the range control module. Ford sets it with the wrench lamp instead of the MIL – on the 2020 Escape and Corsair a misrouted park release cable, on the Mach-E software – and applies the electric parking brake. Ram 1500 (2019) sets the MIL; Stellantis names a used manual park release as the most common cause.
Medium severity. Can I keep driving?Drive gently to a repair shop. If it slips, you hear clunks, or it loses its gears, do not keep driving.
Symptoms
- Park cannot be selected, 'Park not available' message
- Electric parking brake applies automatically
- Wrench lamp (Ford) or MIL (GM, Ram)
- Vehicle may roll away if not secured
Most likely causes
- Manual park release cable misrouted or actuated
- Range actuator misaligned or its coupling offset
- Control module software
- Park lock actuator or its ground faulty
- Range or park position signal wrong
What to check, in order
Start with the simplest. You can tick off each step.
Good to know

- It can trigger limp mode.
- It affects emissions.
What each character of P07E4 means
- P: Powertrain: engine and transmission
- 0: Generic code: same on every make
- 7: Transmission
