What it means
The transmission control system detected that the vehicle is stuck in Drive or could not leave Drive when requested. The code does not identify a particular failed component.
At a glance
- Usually lights the check-engine light
How it works
The transmission control system checks whether the reported range changes when the driver requests a range other than Drive. P07E7 sets when the system continues to detect Drive or cannot confirm the requested change; the code does not identify a particular failed part.
Common causes
Most likely first.
- Shift solenoid sticking or malfunctioning
- Fault in shift actuator or linkage
- Low or degraded transmission fluid
- Hydraulic pressure or valve body fault
- Internal transmission wear or damage
Symptoms
- Unable to shift out of Drive
- Transmission or powertrain warning may appear
How to diagnose it
- Record freeze-frame data and compare requested and reported ranges on a scan tool when another range is selected.
- With the vehicle secured, check whether the selector moves normally and whether its indication matches the range shown by the scan tool.
- Inspect accessible selector linkage or actuator parts and their connectors and wiring for binding, damage, corrosion, or loose connections.
- Check transmission fluid level and condition using the manufacturer's procedure, since fluid problems can affect hydraulic range changes.
- Use the manufacturer's diagnostic procedure to check shift-solenoid commands and hydraulic or valve-body operation against specification.
- If control and hydraulic checks pass, inspect the transmission for internal wear or damage that may prevent Drive from disengaging.
Common fixes
- Repair a binding or misadjusted selector linkage, if fitted.
- Correct low fluid or service degraded fluid according to the manufacturer's procedure.
- Clean and secure affected connectors or repair damaged wiring.
- Replace a shift solenoid or repair a valve-body fault confirmed by testing.
- Repair confirmed internal transmission wear or damage.
Can I keep driving?
Do not drive if the transmission cannot leave Drive or select Park or Neutral reliably; keep the vehicle secured with the parking brake. A stuck range can prevent safe stopping or parking, and forcing the selector may worsen damage.
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.
