What P2263 means
P2263 means boost pressure measured in the intake manifold stays too far from the target set by the closed-loop boost control. CARB requires diesel OBD to detect underboost, overboost and slow response of the boost control. On the 2014 Cruze 2.0 diesel the allowed underboost deviation runs from 35 to 85 kPa with injection quantity and speed, and the code sets as Type A once the condition holds for 15 s; GM's 2018 diesels need 400 failures in 500 samples and name leaks after the compressor or in the manifolds, and exhaust obstructions, as targets. Ford's 2023 diesels count deviations above 35 kPa at 1500 rpm or more, typically over 100 s. The Opel/GM 2.0 CDTi in the Saab 9-5 (2010) waits for more than 200 s out of range and stores it as Type C. GM's Cruze bulletin found a charge-air cooler duct pulled off the throttle body, with P0299, P2002 and P2463 alongside. The engine usually limits torque.

Symptoms of P2263
- Power loss or limp mode
- Hissing or whistling from the charge-air system
- Black smoke under load
Common causes of P2263
- Most likelyCharge-air hose or cooler duct leaking or pulled off
- PossibleVariable-geometry vanes or actuator sticking
- Less likelyRestricted exhaust, for example a heavily loaded particulate filter
- Less likelyBoost pressure sensor reading wrong
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2263 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). |
| 63 | The exact fault in that area. |
What to do next
- Note P2263 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 P2263
What does P2263 mean?
P2263 means "Turbocharger/Supercharger A Boost System Performance". P2263 means boost pressure measured in the intake manifold stays too far from the target set by the closed-loop boost control. It is a generic code, so it means the same on every make.
Is it safe to drive with P2263?
Drive gently and only to a workshop. With P2263 the car can go into limp mode (reduced power) to protect itself.
Will P2263 fail an emissions test?
Yes, it can. P2263 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 P2263 to fix?
Difficulty: medium. A typical repair takes 0.5 to 6 hours of work. This is a job for a workshop.
Will P2263 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
