P2563 Howo — turbo boost control position sensor

Fault codes / P2563

SAE: Turbocharger Boost Control Position Sensor Circuit Range/Performance. Commanded geometry vs actual. Not P0299 (underboost) and not P2263 (turbo system). P2564 is the low-signal sibling. Our ramid table has no P2563 row — we do not invent an SPN. No OEM.

Which trucks see it

Howo T7H, Shacman, Sitrak, Weichai WP10–WP13, MC11/MC13. Often next to P2263/P0299.

Symptoms

• no pull
• MIL with P2263/P0299
• actual VGT does not follow desired
• wet plug after a wash

Likely causes

• SAE: position-sensor circuit/range.
• Carbon / mechanical stop. Wet plug.
• Do not mix with P0299/P2263.

What to check

1. Read actual vs desired VGT.
2. 5 V, ground, signal, plug.
3. Actuator test — do not force the gears. No invented OEM.

Can you keep driving

Limp without full load if the cartridge is quiet. Home form: P2563 or a photo.
