P27DDPressure Control Solenoid T Control Circuit/Open

  • Generic OBD-II code · Powertrain
  • Turns on the check-engine light
  • Matters for the ITP
  • Can trigger limp mode
How the car detects it
P27DD tells that the control circuit of solenoid T is open, so no current reaches the coil. Ford's 2024 OBD overview gives this code to open load on the selector pilot valve of the TR9070 dual-clutch transmission; the document lists the fault type only, without limits. How such a test usually works is shown by GM for the corresponding pilot valve of the Corvette, there coded P282D: with the output off, a sense voltage stuck in the 1.7 to 3.0 V window for 100 ms reveals the missing load (23OBDG07). A dead pilot valve leaves the selector in its rest position, so the synchronizer valves can only reach one group of rods. A displaced terminal, a broken lead or a burnt winding are the usual finds.
