P099FShift Solenoid H Control Circuit High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- High-voltage fault in the control circuit of shift solenoid H, from a short to voltage or, on pull-up driver designs, an open coil or wire. No manufacturer was found to document this code. Genesis' 2017–2018 G80/G90 shift-by-wire, the only documented H user, files its park-function on/off solenoid under P076A and P076D, and bulletin 21-AT-016HG fixes it by replacing valve and electronic module. For the high-side logic, Mitsubishi's six-speed is the nearest model: on solenoid G it treats 3.7 V or more for 0.5 s while commanded off as an open circuit. Ford's summaries give short to power its own code for each of solenoids A to E. CARB requires output circuit checks. P099E is the low side.
- What you may notice

- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
