P2263 on Chevrolet
Turbo/Supercharger Boost System Performance
P2263 on Chevrolet vehicles indicates turbo/supercharger boost system performance. Au7o has documented this code across 1 Chevrolet model — most commonly on Cruze. This code means the computer has detected that the turbocharger or supercharger boost system is not performing as expected, even though no single sensor circuit has failed. The computer compares the actual manifold boost pressure against the target it commanded and sets this code when they don't match for a sustained period. You may notice low power, sluggish acceleration, or limp mode. It signals an overall boost shortfall and usually points to leaks, a failing turbo/charger, or a control component rather than a specific wiring fault. Typical repair costs on Chevrolet range from $100 to $1,400, depending on the specific model and root cause.
Common Causes of P2263
- •Boost/intake leak in piping, hoses, or couplers
- •Failing turbocharger or supercharger
- •Stuck or faulty wastegate or boost control actuator
- •Faulty boost/MAP pressure sensor
- •Clogged or damaged charge air cooler (intercooler)
- •Sticking variable-vane (VGT) mechanism on diesels
- •Faulty boost control solenoid or vacuum supply
- •Restricted air filter or intake restriction

- Turbocharger Wastegate / Bypass Valve Preload Loss - P0299 Underboost2011-2016
The 1.4L turbo's integrated wastegate and spring-loaded bypass valve lose preload with age. The bypass valve spring weakens and stops sealing fully on throttle lift, and the wastegate shaft develops play or sticks, so boost bleeds off and the ECM sets an underboost code. A frequent, much cheaper root cause on the same complaint is the wastegate actuator arm's retaining clip falling off, which lets the arm float free. Owners describe a car that drives normally at light throttle but simply will not pull on a highway on-ramp, sometimes with a rattle from the turbo area.
