P0260: Injection Pump Fuel Metering Control B Intermittent (Cam/Rotor/Injector)
Do not keep driving
Have this diagnosed promptly — intermittent metering faults produce surging and momentary power loss. Report whether the fault is heat-related.
What this code means
The second metering control signal is dropping out intermittently, completing the ten injection pump metering codes spanning P0251–P0260. Read A and B together: a fault on one control implicates that circuit, while both together point at shared supply, fuel quality, or the pump's common electrical feed.

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.
