Code P1287 Description

The P1287 diagnostic trouble code (DTC) indicates that the turbocharger bypass valve is open when it should be closed. This valve is responsible for controlling the flow of exhaust gases to the turbocharger, helping to regulate boost pressure. When the valve is stuck open, it can result in a loss of turbo boost pressure, which can lead to decreased engine performance and fuel efficiency. Additionally, the engine may exhibit hesitation or lack of power under acceleration. If this issue is not addressed, it can potentially cause damage to the turbocharger, engine components, and catalytic converter.
