P2625 Fault Code

Injector Control Pressure Regulator Circuit High

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

The P2625 fault code is triggered when the Engine Control Module (ECM) detects that the injector control pressure regulator circuit is operating at a higher voltage than expected. This component is crucial for ensuring the proper fuel pressure in the fuel injection system, and any issues here can lead to poor engine performance and increased emissions.

What are the symptoms of the P2625 code?

• Poor engine performance
• Difficulty starting the engine
• Increased fuel consumption
• Engine misfires
• Illuminated Check Engine Light

What causes the P2625 code?

• Faulty injector control pressure regulator
• Wiring issues in the injector control pressure regulator circuit
• Short circuits or open circuits in the sensor wiring
• Defective ECM
• Fuel pressure problems caused by a clogged fuel filter or failing fuel pump

How to fix P2625?

• Inspect the wiring harness for damage, wear, or loose connections
• Test the injector control pressure regulator for proper operation and replace if necessary
• Check the fuel pressure and replace the fuel filter or pump if they're faulty
• Clear the fault code and perform a test drive to ensure the issue is resolved
• If the problem persists, consider testing or replacing the ECM.
