What causes a P0090 code?
P0090 is an OBD-II code telling us there is a fault found within the fuel pressure regulator control circuit. This DTC is triggered when the ECM finds out-of-range performance from the control circuit. Out of range performance causes a Check Engine Light and a failsafe mode.
What is the diagnostic code for fuel pressure regulator 1?
P0090 is a diagnostic trouble code (DTC) for “Fuel Pressure Regulator 1 Control Circuit”.
Can a p0090 fuel pressure regulator be malfunctioned?
If actual fuel pressure fails to comply with desired fuel pressure, as calculated by the PCM, a P0090 may be stored and a malfunction indicator lamp (MIL) illuminated. Related fuel pressure regulator engine codes: P0089 Fuel Pressure Regulator 1 Performance
What does the OBD-II code p0090 mean?
P0090 is an OBD-II code telling us there is a fault found within the fuel pressure regulator control circuit. This DTC is triggered when the ECM finds out-of-range performance from the control circuit.
How does the fuel pressure sensor work on a PCM?
When voltage is decreased, the servo retracts and a strong spring forces the valve to close; fuel pressure is decreased. The fuel pressure sensor (usually located in the fuel injector rail) allows the PCM to monitor fuel pressure and adjust fuel pressure regulator voltage accordingly.
What is the diagnostic code for fuel pressure regulator?
A P0090 diagnostic trouble code is referencing an issue with the fuel pressure regulator circuit. This code is similar to P0089, P0091, and P0092. P0090 is an OBD-II code telling us there is a fault found within the fuel pressure regulator control circuit. This DTC is triggered when the ECM finds out-of-range performance from the control circuit.

P0090 is an OBD-II code telling us there is a fault found within the fuel pressure regulator control circuit. This DTC is triggered when the ECM finds out-of-range performance from the control circuit.
How does the fuel pump control module work?
The Engine Control Module ( ECM) uses commanded fuel pump flow to determine a desired fuel rail pressure. The actual fuel pressure is monitored using the Fuel Rail Pressure (FRP) Sensor. Need more information on how to fix the P0090 code?
