Code Definition

P0092 — Fuel Pressure Regulator 1 Control Circuit High

System: Powertrain  |  Type: Generic (OBD-II Standard)  |  Make: Generic

About P0092

P0092 is a generic (obd-ii standard) powertrain diagnostic trouble code. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P0092 is stored, the module has detected a signal or supply voltage higher than the expected operating range.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

Because P0092 is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

The P0092 code indicates a high voltage condition in the control circuit of Fuel Pressure Regulator 1. This regulator is essential in managing the fuel pressure that is supplied to the engine's fuel injectors. The Engine Control Module (ECM) sets this code when it detects that the voltage in the control circuit for the fuel pressure regulator is higher than expected. A high voltage situation in this circuit can result in improper fuel pressure regulation, potentially affecting engine performance, fuel efficiency, and emissions.
