• Solutions

The P2152 fault code indicates an issue with the fuel injector group C supply voltage. This can occur due to an open circuit or a malfunction in the circuit that supplies voltage to the fuel injectors in this specific group. The fuel injectors are crucial for delivering the right amount of fuel to the engine, and issues in their supply voltage can lead to poor engine performance or stalling.

What are the symptoms of the P2152 code?

When the P2152 code is triggered, you may experience symptoms such as:

• Engine misfires or rough idling.
• Decreased fuel efficiency due to improper fuel delivery.
• Difficulty starting the engine or stalling shortly after starting.
• Check Engine Light (CEL) illumination on the dashboard.

What causes the P2152 code?

Common causes of the P2152 code include:

• Damaged or corroded wiring in the fuel injector circuit.
• Faulty fuel injector relay or fuse.
• A malfunctioning Engine Control Unit (ECU).
• Poor connections at the injector or ECU terminals.
• Short circuits affecting the voltage supply to the injectors.

How to fix P2152?

To resolve the P2152 fault code, follow these steps:

• Inspect the wiring and connectors related to fuel injector group C for damage or corrosion.
• Test the fuel injector relay and replace if necessary.
• Check the fuses associated with the fuel injectors and replace any blown fuses.
• Use a multimeter to check for proper voltage at the injector terminals.
• If all else fails, consider reprogramming or replacing the ECU if it's determined to be faulty.
