Fuel Pressure Regulator 1 Control Circuit High
P0092 — Fuel Pressure Regulator 1 Control Circuit High. It is a medium-severity fault: you can usually keep driving for short distances. The most common cause is wire harness problem – poor repair practices, bad wire routing, or other wire harness damage can cause a failure in the frp regulator circuit.
"You can keep driving — for now. 'For now' is doing a lot of work in that sentence."
P0092 is a powertrain diagnostic trouble code. It identifies a fault related to Diesel engines and gasoline direct injection (GDI) engines have something in common: They inject fuel directly into the cylinder on compression. To make this possible, both systems utilize two fuel pumps. A supply pump, mounted in or near the fuel tank, supplies fuel to the secondary pump and, in the case of GDI engines, the port fuel injectors. This primary pressure usually maxes out around 75 psi. The secondary mechanical fuel pump, mounted on the engine, bumps that pressure many times higher,. The powertrain control module monitors this circuit or component continuously and sets P0092 when the signal or value is outside the expected range, implausible or missing. This can affect engine performance, fuel economy or emissions and usually turns on the check-engine light. The base function may still work, but performance can be affected, so the fault should be diagnosed. Diagnosis generally means inspecting the related wiring, connectors and power/ground references, then verifying the component against specification with a scan tool.
