P0092: Fuel pressure regulator control circuit high
The ECU sees a voltage that is too high in the fuel pressure regulator circuit. Usually a broken wire or a connector that has come loose.
| Code | P0092 |

| System | Engine and transmission |
| Group | P00xx, Air, fuel and emissions |
| Type | Generic: it means the same on every make |

What P0092 means
The ECU monitors the voltage in the circuit that drives the fuel pressure regulator. If it sees it above what is possible, it stores this code. The usual cause is an open circuit (broken wire or unplugged connector) or a wire touching a live feed.
Most common causes
- Regulator connector unplugged or with loose pins
- Broken regulator wire
- Chafed wire touching another live wire
- Regulator coil open internally
- Rarely, the ECU
Symptoms
- Engine warning light on
- Loss of power or limp mode
- Hard starting or stalling
- Unstable idle
Can you drive with P0092?
With care You can drive gently, but the engine may lose power or stall. Get it to a garage soon.

How to check it
With the engine off, check that the regulator connector is fully plugged in; it is often left loose after other work. If the code returns after clearing, the garage can test the wire for continuity.
How to read and clear P0092 with Final OBD
Plug an OBD2 scanner in under the steering wheel, switch the ignition on and open Final OBD. Under Faults you’ll see P0092 with its description and whether it’s confirmed, pending or permanent.
If the engine stores it over standard OBD, with FREE you read this code with its explanation for nothing and clear it. With PRO you also read the faults of every control unit and clear them in all of them.
Clearing the code only turns the light off: if the cause is still there, it comes back. Clear it once it’s fixed, and not right before an inspection. It’s all in how to read and clear fault codes and in inspections and OBD.

How do you clear P0092?
With an OBD2 scanner and an app like Final OBD, which clears it for free if it’s stored by the engine control unit. But clearing it only turns the light off: if the cause isn’t fixed, P0092 comes back.
Read it on your car
Final OBD reads and clears engine faults through standard OBD for free, each one explained in plain English. With PRO it also reads the faults of every control unit, each make’s own codes included, and clears them in all of them.
