Frequently Asked Questions

What does P0089 mean on a Power Stroke?

P0089 means Fuel Pressure Regulator 1 Performance. The fuel pressure regulator is not controlling rail pressure the way the engine computer expects.

Is P0089 a Power Stroke-specific code?

No. P0089 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.
