P2263Turbocharger/Supercharger A Boost System Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- 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.
- What you may notice
- Power loss or limp mode
- Hissing or whistling from the charge-air system
- Black smoke under load
- Likely causes
- LikelyCharge-air hose or cooler duct leaking or pulled off
- PossibleVariable-geometry vanes or actuator sticking
- RareRestricted exhaust, for example a heavily loaded particulate filter
- RareBoost pressure sensor reading wrong
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
