What P22D3 means
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.
P22D3 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyHard
- Typical labor0.5 to 6 hours
- Clears after repairAfter a drive cycle
Symptoms of P22D3
- Check engine light on
- Power capped at higher engine speed and load
- Possible overboost code alongside
Common causes of P22D3
- Most likelyValve seized closed by soot or corrosion
- PossibleEngine software setting the code falsely (Jeep Cherokee 2026 bulletin)
- PossibleActuator, linkage or vacuum supply unable to open the valve
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P22D3 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 2 | Area: fuel and air metering (injector circuit). |
| D3 | The exact fault in that area. |
What to do next
- Note P22D3 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P22D3
What does P22D3 mean?
P22D3 means "Turbocharger Turbine Inlet Valve Stuck Closed". P22D3 is stored when the turbine inlet valve does not open on command. It is a generic code, so it means the same on every make.
Is it safe to drive with P22D3?
Drive gently and only to a workshop. With P22D3 the car can go into limp mode (reduced power) to protect itself.
Will P22D3 fail an emissions test?
Yes, it can. P22D3 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P22D3 to fix?
Difficulty: hard. A typical repair takes 0.5 to 6 hours of work. This is a job for a workshop.
Will P22D3 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
