Frequently Asked Questions

What does P0088 mean on a Power Stroke?

P0088 means Fuel Rail/System Pressure - Too High. Measured fuel rail pressure is above what the engine computer is commanding.

Is P0088 a Power Stroke-specific code?

No. P0088 is a generic OBD-II code defined by SAE J2012, so it means the same thing on any vehicle that sets it. The exact conditions Ford uses to set it on its diesels are in Ford service information.

How Do You Diagnose POWERSTROKE-P0088?

  1. Compare desired and actual rail pressure on a scan tool.

  2. Check the pressure regulator or metering valve circuit and its resistance against the specification.

  3. Check the rail pressure sensor reading with the engine off, then inspect the fuel return path.
