- 4Monitor fuel rail pressure readings with a scan tool to identify erratic or excessively high pressure.
- 5Test the fuel pressure regulator's resistance and operation according to manufacturer specifications.
P0092 on Popular Vehicles
Ford F-150
2004-2024Ford F-150s are known for fuel system sensor issues. A P0092 on these trucks frequently points to a failing Fuel Rail Pressure (FRP) sensor or the integrated fuel pressure regulator.
65% fixed by replacing the FRP sensor or regulator
Chevrolet Silverado
2007-2024Silverados can experience P0092 due to issues with the fuel pressure sensor or its wiring. Corrosion in the connector is a common culprit on these trucks.
60% fixed by replacing the fuel pressure sensor or repairing wiring
Honda Accord
2003-2024While less common, P0092 on a Honda Accord typically indicates a faulty fuel pressure sensor or a short in the sensor's wiring harness, often due to age or environmental exposure.

Frequently Asked Questions
What does P0092 mean?
P0092 indicates that the engine's computer has detected a high voltage condition in the electrical circuit that controls the fuel pressure regulator. This means the computer is seeing a signal that is too high from this circuit.
Can I drive with P0092?
No, stop driving. A P0092 code indicates a serious issue with fuel pressure regulation. Driving with this code can lead to engine stalling, severe performance problems, and potential damage to your fuel system or engine due to incorrect fuel delivery.
Will P0092 clear itself?
No, P0092 will not clear itself. This code points to a hard electrical fault or a component failure that requires diagnosis and repair. The Check Engine Light will remain on until the underlying issue is fixed.
How do I fix P0092 myself?
Start by inspecting the fuel pressure regulator's electrical connector and wiring for damage. If the wiring is good, you will likely need to test and potentially replace the fuel pressure regulator or its integrated sensor. A multimeter and a scan tool are essential for proper diagnosis.
How much does it cost to fix P0092?
DIY repair costs for P0092 typically range from $100 to $400, primarily for the cost of a new fuel pressure regulator or sensor. Professional repair at a shop can cost between $200 and $800, including diagnosis, parts, and labor.
P0092 keeps coming back - why?
If P0092 keeps returning, it often means the initial repair did not address the root cause. This can happen if the wiring issue was misdiagnosed, if there's an intermittent short, or if the PCM itself is faulty (though this is less common).
Will P0092 fail emissions/smog test?
Yes, P0092 will cause your vehicle to fail an emissions or smog test. The Check Engine Light being on is an automatic failure in most jurisdictions, and a fuel system fault like this directly impacts emissions.
What's the difference between P0092 and P0091?
P0092 indicates a 'Fuel Pressure Regulator 1 Control Circuit High' meaning the voltage signal is too high. P0091 indicates a 'Fuel Pressure Regulator 1 Control Circuit Low' meaning the voltage signal is too low. Both point to an electrical issue with the regulator's circuit, but in opposite directions.
P0092 on Ford F-150?
On a Ford F-150, P0092 often points to a faulty fuel rail pressure sensor or the fuel pressure regulator itself. These components can fail over time, leading to erratic fuel pressure readings and this specific circuit high code. Always check the wiring first.
Questions to Ask Your Mechanic
Did you check the voltage at the fuel pressure regulator connector?
Good answer: Yes, I measured the voltage and it was consistently above specification, indicating a short to voltage or an internal fault in the regulator.
What were the fuel rail pressure readings with the scan tool?
Good answer: The fuel rail pressure was erratic or consistently too high, even when the engine was off, which points to a faulty sensor or regulator.

Cost of Waiting
Ignoring P0092 can lead to severe engine performance issues, including stalling and hard starting. Continued incorrect fuel pressure can damage your fuel pump, fuel injectors, or even cause engine misfires that harm your catalytic converter. A $200 sensor replacement now prevents a $1,000+ fuel system repair later.
While You're In There...
While not directly related to the electrical fault, a clogged fuel filter can sometimes contribute to fuel pressure issues and is a good maintenance item to replace if it's easily accessible during the repair.
If accessing the fuel rail, inspecting or replacing fuel injector O-rings can prevent future fuel leaks, especially if they are old and brittle.
Tools You'll Need

Your Next Steps
Step 1: Perform a thorough visual inspection of the fuel pressure regulator, its connector, and the wiring harness for any obvious damage or corrosion.
Step 2: Use an OBD-II scan tool to monitor live data for fuel rail pressure. Compare actual readings to desired readings. If the actual pressure is consistently high or erratic, proceed to test the regulator.
Step 3: Disconnect the fuel pressure regulator and use a multimeter to test the voltage at the connector and the resistance of the regulator itself. Compare readings to your vehicle's service manual specifications.
