What P27E0 means
P27E0 reports a control line of solenoid T sitting too high. Ford's 2024 overview of the TR9070 dual-clutch gearbox uses it for a shorted load on the selector pilot valve, a coil or line bypassed to battery so the driver cannot pull current through the winding. Limits are not stated by Ford. On the Corvette, GM tests its comparable pilot valve under P2830 with a supply-dependent voltage limit of 0.7 to 1.1 V, a current-deviation check and a shutdown scan for shorts to neighbouring outputs (23OBDG07). Since the pilot valve then cannot be applied, the selector stays at rest and the gears on the other rod group are lost. Check for a wire touching a feed, shorted coil turns and a cross-short to adjacent valve lines.

- PossibleCross-short to an adjacent valve line
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P27E0 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 7 | Area: transmission. |
| E0 | The exact fault in that area. |
What to do next
- Note P27E0 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 P27E0
What does P27E0 mean?
P27E0 means "Pressure Control Solenoid T Control Circuit High". P27E0 reports a control line of solenoid T sitting too high. It is a generic code, so it means the same on every make.
Is it safe to drive with P27E0?
Drive gently and only to a workshop. With P27E0 the car can go into limp mode (reduced power) to protect itself.
Will P27E0 fail an emissions test?
Yes, it can. P27E0 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 P27E0 to fix?
Difficulty: medium. A typical repair takes 1 to 4 hours of work. This is a job for a workshop.
Will P27E0 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
