OBD-II Generic Error Code P2564: How to Fix It

Q: Can I drive my car with a P2564 code?

You can drive short distances with a P2564 code, but it is not recommended for extended driving. The fault can cause reduced turbo boost, lower power output, and poor fuel economy. In some vehicles, the ECM may enter a 'limp mode' to protect the engine, severely limiting performance. Continued driving without repair can also risk further damage to the turbocharger actuator or related components, potentially turning a moderate repair into a costly one.

Q: What causes a P2564 turbo boost control position sensor low code?

The most common causes include a faulty turbo boost control position sensor, corroded or damaged wiring and connectors at the sensor, a seized or sticking turbocharger actuator, heavy carbon buildup on the variable geometry turbocharger vanes, or in rare cases, a failing engine control module (ECM). Wiring and connector issues are statistically among the most frequent culprits, so always check those first before replacing any parts.

Q: How much does it cost to fix a P2564 code?

Repair costs vary widely depending on the root cause and vehicle type. Wiring repairs or connector cleaning may cost as little as $50-$150 at a shop. A replacement turbo boost control position sensor typically ranges from $50-$200 for the part, plus 1-2 hours of labor. If the turbocharger actuator needs replacement, costs can range from $200 to over $1,000 depending on the vehicle and whether calibration is required. If the full turbocharger needs cleaning or replacement, costs can exceed $1,500-$3,000.

Q: Will cleaning the turbocharger fix a P2564 code?

In some cases, yes. Carbon buildup on the variable geometry vanes of a VGT turbocharger is a known cause of actuator and sensor faults. If the actuator is sticking due to carbon deposits rather than mechanical failure, cleaning the turbo vanes — either using a specialized intake cleaner or by physically removing and cleaning the turbo — can resolve the fault. However, if the sensor itself or the wiring is faulty, cleaning alone will not fix the code.

Q: Is P2564 the same as P2563 or P2565?

These codes are related but not identical. P2563 indicates the turbo boost control position sensor signal is out of range in general, P2564 specifically means the signal is too low (below the minimum threshold), and P2565 means the signal is too high (above the maximum threshold). All three relate to the same sensor and actuator system, but the specific direction of the fault (low vs. high) can help narrow down the cause. P2564 specifically suggests an open circuit, poor ground, or a sensor producing a weak signal.

Abstract

The P2564 error code indicates that your vehicle's turbo boost control position sensor is reporting a signal that is lower than expected, which could mean the sensor itself is faulty, a wiring issue is present, or the turbocharger actuator is not functioning correctly. This code is triggered when the engine control module (ECM) detects a voltage reading from the turbo boost control position sensor that falls below the minimum threshold. Left unaddressed, this issue can cause reduced engine performance, poor fuel economy, and potential damage to the turbocharger system.
