Cause
Faulty fuel rail pressure sensor
The sensor closing the loop on high-pressure fuel control. A sensor reading low makes the module raise real pressure to correct an imaginary shortfall, which stresses the pump and injectors — so this is one of the few sensor faults that can damage what it monitors.
Typically a moderate job.
Some of these codes mean you should stop driving
9 of the 17 codes this can cause indicate a fault where continuing to drive risks damage or is unsafe. Which one you have matters more than the cause does — read the code's own page before deciding.
Codes this can cause (17)

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.
