P0092: Fuel Pressure Regulator A Control Circuit High
Do not keep driving
Expect starting difficulty or reduced power. Diagnose before extended driving.
What this code means
Voltage on the regulator control circuit is above the expected range, indicating a short to supply or an open circuit. Measure the regulator's winding resistance directly; an open winding and a broken wire look identical from the module's side.
Likely causes
Start here
- Open circuit in regulator control wiring · moderate
- Wiring shorted to voltage · moderate
- Failed fuel volume regulator · moderate
Less common
- Corroded or loose connector · easy

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.
