What the P0190 code means. The power control module (PCM) has detected that the fuel rail pressure sensor is not within range. This range has been set by the car’s manufacturer.
Where is the fuel rail pressure sensor circuit?
The fuel rail pressure sensor is located on the engine. Once you remove the engine cover, you will be able to see the fuel rail. The fuel rail pressure sensor is mounted on the fuel rail. If you are getting fault code P0190, check for power at the sensor.
What is a P0190 code?

What causes fuel rail pressure Code?
Trouble Code: P0087 Fuel Rail/System Pressure – Too Low
There is a sensor on the fuel rail that monitors fuel pressure and determines if the vehicle needs more or less fuel. When your vehicle’s Engine Control M (ECM) records a code of P0087, it means the fuel pressure in the system is below specification.
What causes code P0087?
If the fuel levels reach critically low levels, the PCM may set a code P0087 even though it has nothing to do with the fuel rail’s pressure levels. A broken or dirty fuel filter is one of the possible causes of code P0087.
How do you test a fuel rail pressure sensor?
The fuel pressure sensor is part of the fuel system on a car.
- Disconnect the Fuel Pressure Sensor.
- Turn on Your Car’s Engine.
- Check for the Voltage of the Harness’ Connections.
- Compare the Values of Voltage of the Harness’ Connections Against What’s Written in Your Car’s Manual.
- Check the Wirings on Your Car.
