P0192: Fuel Rail Pressure Sensor Circuit Low Bank 1
Do not keep driving
Expect a limp mode or a no-start. If other sensor codes appeared at the same moment, say so — that pattern points at one shared supply fault.
What this code means
The rail pressure signal is below its valid range, typically a short to ground or a lost reference supply. The module reads this as almost no rail pressure and responds accordingly. Where several sensors report low simultaneously, check the shared five-volt reference before testing each sensor in turn.
Likely causes
Start here
- Wiring shorted to ground · moderate
- Failed sensor reference voltage supply · moderate
- Faulty fuel rail pressure sensor · moderate
Less common

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.
