OBD-II Code
P0247
Severity
Not yet reviewed
Nobody on our side has assessed this code yet, so we are not going to guess at how serious it is.
Can you drive it
We cannot say
Treat it as unknown until a shop reads it with live data. If the check-engine light is FLASHING, stop driving as soon as it is safe to — that means an active misfire, whatever the code.
Indicative cost (USD)
$140–$580
From this code's diagnostic notes. Varies by vehicle, diagnosis, parts, and local labor. This is not a repair quote.
P0247 indicates a general electrical fault in the turbocharger wastegate solenoid B control circuit, used on twin-turbo, twin-scroll, or sequentially-staged setups where solenoid B controls the secondary or rear-bank wastegate.
How a shop works this
Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed.
Note every code that is set, not just this one.
Codes that appear together usually narrow the cause faster than any one of them read alone.
Read the freeze frame — the conditions the fault was recorded under.
Cold or warm, idle or load, road speed and engine speed. A fault that only appears cold is a different fault from one that only appears under load, even with the same code on the scanner.
Confirm the fault is current rather than history.
Clear the code and see whether it returns under those same conditions. A code that does not come back may have been logged during a repair, a flat battery, or a bad connection that has since been disturbed.
Then follow the diagnostic notes further down this page, in the order they are written.
They are written in the order a shop works this code, cheapest checks first. Where they name a component, inspect its wiring and connector before replacing it.
If the code comes back after a repair, the underlying fault is still there. That is the point to bring in a scanner with live data and freeze-frame, or a shop that has one.

Cheapest path
identify which physical solenoid is B on your platform (often the rear or passenger-bank unit on V-configuration twin-turbos), then unplug it and measure resistance across the terminals, expecting 14-30 ohms on most applications. Inspect the connector for oil contamination from upstream turbo seal weep, a leading cause on high-mileage twin-turbo engines. The expensive misdiagnosis is condemning the secondary turbocharger ($1,500-$3,000 plus labor) when bank-correlated codes like P0247 almost always trace to the cheaper solenoid or its harness.
