P2263 on Hyundai
Turbo/Supercharger Boost System Performance
P2263 on Hyundai vehicles indicates turbo/supercharger boost system performance. Au7o has documented this code across 1 Hyundai model — most commonly on Veloster. 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 Hyundai range from $50 to $1,500, 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

Hyundai Veloster(1 issue)
- Turbo Wastegate Rattle at Idle2013-2018
The turbocharger wastegate actuator on the Veloster Turbo develops a distinctive rattle at idle, caused by wear in the wastegate linkage and internal spring tension loss. While mostly cosmetic and not immediately harmful, prolonged wastegate issues can affect boost control and lead to overboosting or underboosting conditions.
