P099DShift Solenoid H Control Circuit Range/Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- Electrical feedback from the drive circuit of shift solenoid H does not fit the command, although no hard short or open is seen. No manufacturer was found to document this code. Solenoid H means an eighth shift solenoid. The only documented H user, the 2017–2018 Genesis G80 and G90, reports its on/off solenoid for the shift-by-wire park function under P076A and P076D, outside this block. Ford's OBD summaries describe shift solenoid checks only up to E, with separate open, short to ground and short to power codes and 0.5 to 5 s electrical monitoring. CARB requires transmission outputs to be checked for proper function. Low and high are P099E/P099F, the open circuit is P09A1.
- What you may notice
- Warning light depending on calibration

- PossibleHigh-resistance connector or harness contact
- RareWeak driver stage in the transmission control module
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
