P22D3 Turbocharger Turbine Inlet Valve Stuck Closed

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.

Likely causes

Valve seized closed by soot or corrosion
Engine software setting the code falsely (Jeep Cherokee 2026 bulletin)
Actuator, linkage or vacuum supply unable to open the valve

Symptoms

  • Check engine light on
  • Power capped at higher engine speed and load
  • Possible overboost code alongside
