Turbocharger Boost Control Position Sensor Range/Performance Problem
There's an issue with the turbocharger boost control sensor's readings.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The computer isn't getting the right information from the sensor that controls how much boost the turbo should create, which could lead to poor performance.
What the computer is actually seeing
The electronic control unit (ECU) expects the boost control position sensor to indicate a specific voltage level, usually between 0.5V to 4.5V depending on the boost demand. When it falls outside this range, or the response is too slow, the code triggers.
What a healthy reading looks like
Voltage from the boost control position sensor should match the specified range given in the vehicle service manual, typically around 0.5V at idle and up to 4.5V at full boost.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 11. Inspect the wiring and connectors for the turbocharger boost control position sensor. Look for fraying, corrosion, or loose connections. If found, repair or replace as needed. Decision: If wiring is okay, move to step 2; if there's damage, fix it and retest.
Common causes
- Faulty turbocharger boost control position sensor
- Wiring issues or bad connectors for the sensor
- Turbocharger actuator problems
- Restricted vacuum or pressure lines
- Turbo underperformance or damage

Frequently asked questions
Is it safe to drive with this code?
It's drivable, but expect decreased power and fuel economy. Fix it soon.
Will this code come back after resetting it?
If the root cause isn't resolved, yes, it will return.
Why does this code pair with P2566?
P2566 indicates a voltage out of range for the sensor, while P2567 confirms there's a performance issue, often related.
