P08D8Shift Solenoid K Electrical
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- Collective electrical fault for shift solenoid K, used by makers that do not split circuit faults into low, high, open or range codes. No manufacturer documents this code publicly. The pattern exists for earlier letters: Hyundai stores P0753 (shift control solenoid valve A electrical) on the Genesis G80 and G90 8-speed and, per bulletin 21-AT-016HG, replaces the solenoid once the harness checks out, with valves listed only up to F. Ford's electrical check fails a solenoid when the driver feedback contradicts the command for 0.5 to 5 seconds. CARB requires circuit monitoring of transmission outputs. P08DA to P08DD are the detailed codes. The TCM usually reacts at once with altered shifting.
- What you may notice
