P22D3Turbocharger Turbine Inlet Valve Stuck Closed
- 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
- P22D3 is stored when the turbine inlet valve does not open on command. In a series two-stage layout all exhaust must then pass the small high-pressure stage even at high load, raising back-pressure and risking overboost or turbo overspeed, so the module caps power. In a parallel-sequential layout the second turbo never comes in. Stellantis documents the code on the 2026 Jeep Cherokee with the 1.6 litre turbo hybrid: bulletin 18-052-26 Rev. A (June 2026) states that P22D3-00 sets falsely on vehicles built from mid-December 2025 to late April 2026 and adds PCM software that disables it. On other vehicles, check for a valve seized by soot, a failed actuator or a lacking vacuum supply. P22D2 is the opposite, a valve stuck open.
- What you may notice
- Check engine light on

- PossibleActuator, linkage or vacuum supply unable to open the valve
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
