P08D5Shift Solenoid K
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- Base code for shift solenoid K, the eleventh on/off shift valve in SAE's lettering. Which valve carries the letter is up to the manufacturer, and none documents K publicly: Ford's gasoline OBD summary lists shift solenoids only up to SS E, Hyundai's bulletin 21-AT-016HG for the Genesis 8-speed ends at shift control solenoid F, and GM's 2016 to 2025 tables contain no code of the K group. Ford shows how a base code can be used: its P0750 stands for an open circuit of solenoid A. CARB requires functional and circuit monitoring of shift solenoids. P08D6 to P08DD split the fault into functional and circuit types. Expect harsh or missing shifts and possibly a fixed substitute gear.
