• Solutions

The P2587 fault code indicates a problem with the turbocharger boost control position sensor B. This sensor measures the position of the turbocharger's actuator and communicates this data to the engine control module (ECM). When the ECM detects that the sensor is reporting a value outside of the expected range, it triggers the P2587 code. It's essential for maintaining optimal boost pressure for engine performance.

What are the symptoms of the P2587 code?

Common symptoms associated with the P2587 code may include:

• Reduced engine power and acceleration
• Poor fuel economy
• Increased exhaust emissions
• Unusual turbocharger performance
• Check Engine Light (CEL) illuminated on the dashboard

What causes the P2587 code?

Several issues could cause the P2587 code, including:

• Faulty turbocharger boost control position sensor B
• Damaged wiring or connectors in the sensor circuit
• Mechanical issues with the turbocharger or actuator
• Vacuum leaks affecting the operation of the actuator
• Engine control module (ECM) issues

How to fix P2587?

To resolve the P2587 fault code, the following steps can be taken:

• Inspect and test the turbocharger boost control position sensor B for proper function.
• Check for any damaged wiring or connectors in the sensor's electrical circuit.
• Verify the operation of the turbocharger and actuator, looking for mechanical issues or blockages.
• Clear the fault code and take the vehicle for a test drive to ensure the issue is resolved.
• If the problem persists, consider replacing the turbocharger boost control position sensor B or consulting a professional mechanic.
