This summary uses the existing diagnostic information shown in full below.
This code means that the computer in your car thinks there's too much pressure in the system that controls how much fuel gets injected into the engine.
The P2625 code is triggered when the Engine Control Module (ECM) detects a high voltage condition in the injector control pressure regulator circuit.
The injector control pressure regulator is responsible for maintaining the correct pressure in the fuel injection system. If the ECM detects that the voltage in this circuit is higher than expected, it sets the P2625 code. This could be due to a faulty pressure regulator, wiring issues, or a malfunctioning ECM.
• Check Engine Light is on
• Poor engine performance
• Engine may run rough or stall
• Faulty injector control pressure regulator
• Wiring issues or poor electrical connections
• Malfunctioning Engine Control Module (ECM)
ECM: Engine Control Module
OBD-II: On-Board Diagnostics, Second Generation
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage or corrosion.
• Test the injector control pressure regulator for proper operation.
• Repair or replace damaged wiring or connectors.
• Replace the injector control pressure regulator if faulty.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Ford F-250
• Chevrolet Silverado
• Dodge Ram
• Regular maintenance and inspection of the fuel system.
• Ensure proper electrical connections.
• Use quality fuel and additives.
Engine Performance
• Do not ignore the Check Engine Light.
• Get the vehicle diagnosed as soon as possible to prevent further damage.
Check with the vehicle manufacturer for warranty coverage on emissions-related components.
This code has been associated with issues in diesel engines, particularly in trucks, due to their complex fuel systems.
Moderate – It should be addressed soon to avoid potential engine performance issues.
Driving with a malfunctioning fuel system can lead to increased emissions and potential safety risks.
• Engine running
• Vehicle at operating temperature
The injector control pressure regulator is typically located on or near the fuel rail or injector pump.
Q: Can I drive with a P2625 code?
A: It's not recommended to drive for long periods with this code, as it can lead to poor engine performance and increased emissions.
Q: How can I reset the Check Engine Light after fixing the issue?
A: You can use an OBD-II scanner to clear the code after the repair is completed.
