P27E0 Pressure Control Solenoid T Control Circuit High

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.

Likely causes

Control wire shorted to a supply feed
Shorted turns in solenoid T
Cross-short to an adjacent valve line

Symptoms

  • MIL on
  • Gears of one rod group lost
  • Fallback mode
