Unmetered air sneaking in to the intake.
Look for vacuum leaks.
O2 sensor/leaky injecters/fuel pressure regulator.
there is no fuel pressure regulator " sensor ", there is a fuel pressure regulator controled by vacuum located at the front end of the fuel rail.
The fuel tank pressure sensor is actually the fuel pressure regulator. There is a sensing unit within the regulator.
there is none.there is a pressure regulator however.and there is a tank sensor sometimes that measures pressure in the tank. but not on all vehicles.
The fuel pressure sensor is located on the fuel rail attached to the fuel pressure regulator.
Are you referring to the (oil pressure sensor) or the (oil pressure regulator)?
The fuel pressure regulator is underneath the fuel filter bowl on the righthand side of the motor. It has a two wire connector plug that goes into it. Also it is underneath the oil pressure sensor switch.
It has a 2.2L and i have replaced fuel pressure regulator plugs map sensor and to other sensors on the throttle body. Driving habits may be an issue.
No, the sensor will need replaced.
check fuel pressure regulator
Does not have a regulator. There is a sensor on the driver side fuel rail under the upper intake manifold
A fuel rail pressure regulator could cause trouble.
