The P2150 fault code indicates an issue with the fuel injector group B supply voltage circuit being too low. This could suggest problems with the electrical connections, the fuel injectors themselves, or the engine control module (ECM) that regulates fuel delivery. Diagnosing this issue is critical as it can lead to engine performance problems or even stalling.

What are the symptoms of the P2150 code?

• Reduced engine power and performance
• Poor fuel economy
• Engine stalling or refusal to start
• Rough idling or misfires during operation
• Illuminated check engine light on the dashboard

What causes the P2150 code?

• Faulty fuel injectors in group B
• Damaged or corroded wiring in the injector circuit
• Poor ground connections affecting voltage supply
• Issues with the engine control module (ECM) that controls the injectors
• Blown fuses or relay failures in the fuel injector circuit

How to fix P2150?

• Inspect and repair any damaged wiring or connectors related to fuel injectors in group B.
• Test the fuel injectors for proper operation and replace if faulty.
• Check the ground connections for integrity and ensure they are secure.
• Replace any blown fuses or malfunctioning relays in the system.
• Reprogram or replace the ECM if it’s found to be the source of the issue.
