P2263 on Mazda
Turbo/Supercharger Boost System Performance
P2263 on Mazda vehicles indicates turbo/supercharger boost system performance. Au7o has documented this code across 1 Mazda model — most commonly on CX-50. 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.
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

- Turbo Wastegate Rattle on Cold Start2023-2025
The turbocharger wastegate actuator rattles audibly on cold start and during warm-up on the 2.5T engine. The wastegate flapper has slight play in its pivot, causing a metallic rattle until exhaust gas pressure and temperature stabilize. Mazda has acknowledged this as a characteristic of the turbo design but some cases involve excessive wear.

What does P2263 mean on Mazda?▼
P2263 stands for "Turbo/Supercharger Boost System Performance." 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.
