P282F reports a ground fault on the control line of solenoid K. On the 2023 Corvette, GM checks the selector pilot valve while its low-side output is switched on; the TCM compares the voltage at the sense pin with a lower limit of about 1.7 V, and a reading below it points to a ground short. After 100 ms the module stores a Type A code, so the MIL lights during the same trip. Battery voltage has to lie between 8.75 and 18 V and the engine must not be cranking. Ford's TR9070 summary uses P27DF for a shorted switch at its own selector pilot valve instead. Expect gears on one clutch shaft to be blocked; chafed insulation inside the transmission harness is the first thing to look for.

Likely causes

Control wire to valve K shorted to ground
Damaged insulation inside the transmission harness
Coil of valve K shorted to ground internally

Symptoms

  • Gears on one clutch shaft blocked
  • MIL on in the same trip
  • Limp mode
