P27DEPressure Control Solenoid T Control Circuit Range/Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P27DE would be set if the circuit of solenoid T is intact but delivers readings the controller considers implausible. No manufacturer documents the code. For the selector pilot valve of the TR9070, Ford's 2024 summary knows just three electrical faults, namely open load, shorted load and shorted switch, and GM checks the comparable Corvette pilot valve under its own K-block codes. CARB 13 CCR 1968.2 prescribes the general circuit and function monitoring for such actuators. Where a module does use P27DE, it hints at a gradual change rather than a clean break: a terminal with rising contact resistance, a coil whose resistance has crept away from nominal, or an output stage in the TCM that no longer regulates current properly.

- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
