What P22CC means
P22CC indicates that the drive line of the compressor outlet switching valve carries more voltage or current than allowed, usually a short to a battery feed or a solenoid with shorted windings. The output stage of the engine control module then tends to shut down for self-protection, which leaves the switching valve unpowered and the outlet flap in its rest position. On register or two-stage charging this typically means the second compressor branch is no longer brought in or taken out as planned. The test is electrical and continuous, as CARB requires for monitored output parts. No manufacturer publicly documents P22CC. Measure coil resistance against the specification and check whether the wire touches a positive feed; replacing the module is a last resort.
P22CC at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyEasy, DIY possible
- Typical labor0.3 to 2 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P22CC
- Check engine light on
- Outlet flap no longer switches, power reduced
- Fault returns as soon as the valve is commanded
Common causes of P22CC
- Most likelyControl wire shorted to a battery-voltage feed
- PossibleShorted windings in the switching solenoid
- Less likelyFaulty output stage in the engine control module
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P22CC 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). |
| CC | The exact fault in that area. |
What to do next
- Note P22CC 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 P22CC
What does P22CC mean?
P22CC means "Turbocharger Compressor Outlet Switching Valve Control Circuit High". P22CC indicates that the drive line of the compressor outlet switching valve carries more voltage or current than allowed, usually a short to a battery feed or a solenoid with shorted windings. It is a generic code, so it means the same on every make.
Is it safe to drive with P22CC?
Drive gently and only to a workshop. With P22CC the car can go into limp mode (reduced power) to protect itself.
Will P22CC fail an emissions test?
Yes, it can. P22CC 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 P22CC to fix?
Difficulty: easy. A typical repair takes 0.3 to 2 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P22CC clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
