P0254: Injection Pump Fuel Metering Control A High (Cam/Rotor/Injector)
Do not keep driving
Expect poor running or a no-start. Have the wiring and solenoid resistance checked before pump replacement is discussed.
What this code means
The primary metering control circuit is reading high — a short to supply, or an open circuit. An open winding inside the pump presents identically to a broken wire at the module, so test at the pump's own connector to separate them.
Likely causes
Start here
- Open circuit in solenoid wiring · moderate
- Wiring shorted to voltage · moderate
- Failed fuel metering control solenoid · specialist
Less common
- Corroded or loose connector · easy
Rare
- Control module driver failure · specialist

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
