What P07E4 means
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.

Symptoms of P07E4
- 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
Common causes of P07E4
- Most likelyManual park release cable misrouted or actuated
- PossibleRange actuator misaligned or its coupling offset
- PossibleControl module software
- PossiblePark lock actuator or its ground faulty
- Less likelyRange or park position signal wrong
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P07E4 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 7 | Area: transmission. |
| E4 | The exact fault in that area. |
What to do next
- Note P07E4 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P07E4
What does P07E4 mean?
P07E4 means "Unable to Engage Park". 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. It is a generic code, so it means the same on every make.
Is it safe to drive with P07E4?
Drive gently and only to a workshop. With P07E4 the car can go into limp mode (reduced power) to protect itself.
Will P07E4 fail an emissions test?
Yes, it can. P07E4 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P07E4 to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will P07E4 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
