P0092 Fault Code
P0092 OBD-II Trouble Code Short Description
Fuel Pressure Regulator 1 Control Circuit High
What does trouble code P0092 mean?
P0092 is a diagnostic trouble code (DTC) that indicates a high voltage condition in the fuel pressure regulator 1 control circuit. This means that the engine control module (ECM) is detecting an abnormal voltage level in the circuit responsible for regulating the fuel pressure.
The high voltage in the fuel pressure regulator control circuit can be caused by various issues such as a faulty fuel pressure regulator, a short circuit in the wiring, a damaged connector, or a malfunctioning ECM.
To resolve the P0092 fault code, a thorough diagnosis is required to identify the root cause of the high voltage condition. This may involve inspecting the fuel pressure regulator, checking the wiring and connectors for any damage, and testing the ECM for proper functioning. Once the root cause is identified, the necessary repairs or replacements can be carried out to rectify the issue and clear the fault code.
It is important to address the P0092 fault code promptly to prevent any potential drivability issues or damage to the vehicle's engine and fuel system.
