Turbocharger Compressor Outlet Switching Valve Control Circuit High
This code is in our catalogue but has not yet been through editorial review, so the guidance below is limited to what our structured data supports. We publish deeper diagnostic content only after a code has been reviewed — here is why.
Compressor outlet switching valve drive line stuck high — short to B+. Boost control tracks commanded vs. actual manifold pressure; persistent deviation means wastegate, vanes, hose or actuator are not delivering the requested pressure.
A trouble code records what a control module measured. It does not identify which part failed. Test before replacing anything.

|---|---|---|---|
| 1 | Short to B+ | Very common | — |
| 2 | Connector pins corroded - high contact resistance | Occasional | — |
