P08DDShift Solenoid K 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
- Signals that the control circuit of shift solenoid K is open, so commanding the valve produces no current: a broken wire, a pushed-out terminal, a burnt coil or a failed internal transmission harness. No manufacturer documents this code publicly. Ford handles opens through the base code of each solenoid, P0750 for solenoid A, while GM's tables fold them into the circuit-high code P0974, so a separate open code like this one stays unused in both systems. CARB requires transmission outputs to be checked for opens. P08DB and P08DC are the short-circuit codes, P08D8 the general electrical fault. Without power the valve stays in its rest position, so one gear range drops out.
- What you may notice
- Check engine or transmission warning light on
- Some gears no longer available
- Limp mode with fixed gear
- Likely causes
- LikelyBroken wire or pushed-out terminal
- PossibleFailed internal transmission harness
- PossibleBurnt-out solenoid coil
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
