Usual causes, most likely first

boost leak (split intercooler hose, loose clamp)
vacuum hose or boost control solenoid fault
turbo vanes or wastegate sticking with soot
faulty boost pressure sensor

P2263 by make

Audi

Turbo boost system performance fault. Usually hoses or the boost control solenoid.

Usual causes: boost or vacuum hoses leaking, blocked or connected wrong; faulty boost control solenoid (N75); turbo actuator position sensor (G581) reading high

Ford

Turbo boost system performance: boost is not doing what the engine computer expects. On Ranger usually a leak in the charge air side.

Usual causes: boost leak from intercooler or hoses; faulty turbo actuator; sticking turbo vanes

Land Rover

Turbo boost system performance: boost does not match what the engine asked for. On TDV6/SDV6 Discovery and RR Sport it usually brings 'restricted performance' under load.

Usual causes: cracked plastic inlet manifold (3.0 TDV6/SDV6); split intercooler or boost hose, loose clamp; sticking turbo actuator or vanes; MAF sensor reading wrong

Mazda

SkyActiv-D: turbo regulating valve control range/performance fault. Usually wiring, fuse or the regulating solenoid valve.

Usual causes: regulating solenoid valve or connector; ENGINE2 15 A fuse or power supply; regulating valve position sensor wiring

Mitsubishi

Turbo boost system performance fault: boost not following the target.

Usual causes: VGT vanes sticking from carbon; boost leak; faulty boost sensor; exhaust restriction (blocked DPF)

Skoda

Turbo boost system performance fault. Usually hoses or the boost control solenoid.

Usual causes: boost or vacuum hoses leaking, blocked or connected wrong; faulty boost control solenoid (N75); turbo actuator position sensor (G581) reading high

Volkswagen

Turbo boost system performance fault. Usually hoses or the boost control solenoid.

Usual causes: boost or vacuum hoses leaking, blocked or connected wrong; faulty boost control solenoid (N75); turbo actuator position sensor (G581) reading high

Volvo

Turbo boost system performance: boost does not match demand. Common Volvo D5 limp-mode code.

Usual causes: boost hose or intercooler leak; turbo actuator fault; MAF/boost sensor reading wrong

Before you clear it

Write the code down or photograph the scanner first. A code that comes straight back after clearing points to a fault that is still there. A car whose codes were cleared just before you arrived may be hiding one: the scanner's readiness monitors show "not ready" for a while after codes are cleared.

Researched by Credov from manufacturer and workshop sources. A fault code points to where a fault may be; a workshop confirms it with a diagnosis. Browse all fault codes.
