How do I fix code P0193?
What repairs can fix the P0193 code?
- Add fuel to the fuel tank.
- Repair broken or shorted wires.
- Repair corrosion of the wiring and/or connectors.
- Replace clogged fuel filter.
- Replace fuel pump relay.
- Replace fuel pump fuse.
- Replace fuel pump.

What causes P0193?
What are the Possible Causes of the P0193 Code? A high fuel rail pressure signal condition may be caused by an electrical or mechanical fault. The cause may depend on the vehicle manufacturer, fuel system, and fuel type. You are likely to fail an emissions test if your car has code P0193.
Where is fuel rail pressure sensor?
A fuel rail pressure sensor (commonly known as a fuel pressure sensor) is used in many diesel and some gasoline engines. This sensor is usually located near the middle of the fuel rail and is linked to the engine control unit (ECU), which is the central computer of a vehicle.
What does the p0193 code on the fuel rail sensor mean?
Fuel rail pressure data is one of the variables that the PCM uses to calculate the amount of fuel that needs to be delivered to the engine. If the PCM receives a signal from the fuel rail pressure sensor that is abnormally high over a set period, the P0193 code may be registered.
What is the FRP sensor on a fuel rail?
The Fuel Rail Pressure (FRP) sensor is a diaphragm strain gauge device in which resistance changes with pressure.
What causes fuel rail pressure sensor to fail?
Here are some of the most common. RPS Failure – The fuel rail pressure sensor, like most semiconductor sensors, is prone to failure from heat and vibration, both of which are present in abundance in the engine compartment. This is the most common failure in the system. What are the symptoms of code P0193 ?
What is the OBD code for a fuel rail sensor?
OBD2 Code P0193 Volvo definition: The Fuel Rail Pressure (FRP) sensor is a diaphragm strain gauge device in which resistance changes with pressure. The electrical resistance of a strain gauge increases as pressure increases, and the resistance decreases as the pressure decreases.
