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
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 causes a DTC fuel meter to fail?
Depending on year, make, and model, DTC P0090 may have number of causes. Here are some of the most common. Wire Harness Problem – Poor repair practices, bad wire routing, or other wire harness damage can cause a failure in the FRP regulator circuit. FRP Regulator Problem – A faulty solenoid coil in the FRP regulator can cause this problem.
What does diagnostic trouble code DTC stand for?
This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles (GMC, Chevy, Chrsyler, Dodge, Jeep, Mitsubishi, VW, Toyota, etc.). Although generic, the specific repair steps may vary depending on make/model.
