Injector Control Pressure Too High

Where it lives

For P2288, start at the injector the description names.

Check these first

• A stuck or failed fuel pressure regulator
• A clogged fuel return line raising rail pressure
• A failed injector control pressure sensor reading high
• A restriction in the fuel return path

What to do next

1. Read injector control pressure on a scan tool
2. Verify rail pressure with a mechanical gauge
3. Inspect the fuel return line for a kink or clog
4. Test the fuel pressure regulator for a stuck closed position
5. Replace the fuel pressure regulator if pressure stays high
6. Clear the code and retest
