P27DCPressure Control Solenoid T Intermittent
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- With P27DC the module reports that solenoid T misbehaved only briefly before working again. No maker has published a description of this code. Ford's TR9070, the only known application of a valve T (selector pilot valve, 2024 overview), is covered by lasting electrical codes and by stuck-on and stuck-off codes, none of them sporadic. CARB 13 CCR 1968.2 requires the transmission actuators to be monitored. Because the selector pilot valve decides which rods the shift valves reach, even a short dropout can make a gear selection fail or arrive late. Freeze-frame data showing temperature and road conditions at the moment of the fault help more than a single resistance check in the workshop.
