P2564 Fault Code

Turbocharger Boost Control Position Sensor A Circuit Low

• What does that mean?
• Symptoms
• Causes
• Solutions

The P2564 fault code indicates an issue with the Turbocharger Boost Control Position Sensor A Circuit, specifically that it is reading a low signal. This fault code can affect vehicle performance, particularly in acceleration and turbo response.

• Understanding the Sensor: The turbocharger boost control position sensor measures the position of the turbocharger's wastegate, which regulates boost pressure.
• Symptoms: Drivers may notice reduced engine power, delayed acceleration, or the vehicle going into limp mode as a result of this issue.

What are the symptoms of the P2564 code?

Common symptoms associated with the P2564 code include:

• Decreased power output from the engine.
• Poor acceleration, especially under load.
• The vehicle struggling to maintain speed on inclines.
• Check Engine Light (CEL) illuminated on the dashboard.
• Possible stalling or hesitation when accelerating.

What causes the P2564 code?

This fault can be attributed to various factors, including:

• Faulty or damaged turbocharger boost control position sensor.
• Electrical issues such as wiring problems or short circuits in the circuit.
• Issues with the turbocharger itself, such as stuck wastegate or mechanical failures.
• Vacuum leaks or pressure leaks in the intake system, affecting boost pressure.

How to fix P2564?

To resolve the P2564 fault code, the following steps may be taken:

• Inspect and, if necessary, replace the turbocharger boost control position sensor.
• Check all related wiring and connectors for signs of damage, corrosion, or loose connections.
• Test the turbocharger's wastegate for functionality and inspect for any sticking or mechanical failures.
• Repair any vacuum or pressure leaks present in the intake system.
• Clear the fault code and monitor for any return of the issue after repairs.
