What it means
The transmission control system detected that the vehicle is stuck in Park or could not leave Park when requested. The code does not identify a particular park mechanism design.
At a glance
- Usually lights the check-engine light
How it works
The transmission control system checks whether the vehicle can leave Park when another range is requested. P07E6 sets when it still detects Park or cannot confirm the requested change; it does not specify the design of the park mechanism.
Common causes
Most likely first.
- Park pawl jammed under load
- Failed park actuator
Symptoms
- Unable to shift out of Park
- Transmission or powertrain warning may appear
How to diagnose it
- Keep the parking brake applied, record freeze-frame data, and check scan-tool commanded and reported ranges while attempting a safe shift.
- Confirm the brake pedal is applied and inspect the brake lamps, since a brake-switch signal may be required to release Park.
- Check whether the selector indication changes and inspect accessible selector, actuator, and transmission wiring and connectors for damage or corrosion.
- If the vehicle is on a slope, secure it and relieve driveline load only as described in the owner's manual, because load on the pawl can make it difficult to release.
- Use the manufacturer's diagnostic procedure to test the park actuator and its electrical circuit, if fitted, and check for a binding parking mechanism.
Common fixes
- Apply the brake pedal fully and correct a confirmed brake-switch or brake-lamp circuit fault.
- Secure the vehicle and relieve pawl load following the owner's manual.
- Repair damaged wiring or clean and secure a faulty selector or actuator connector.
- Replace a failed park actuator or repair a confirmed binding park mechanism.
Can I keep driving?
Keep the parking brake applied and do not force the selector or drive the vehicle until it can leave Park normally. If it remains stuck, arrange assistance or recovery; forcing the mechanism can damage the selector or transmission.
A code shows where the control module detected a fault, not always which part failed. Check the causes in order and confirm with a test before replacing parts. Have several codes? Check them together
This is a generic code: it means the same on every make. The car’s maker may add more detail in its own service information.
