What are the Signs of a Faulty Fuel Rail Pressure Sensor in a Car

WHAT ARE THE SIGNS OF A FAULTY FUEL RAIL PRESSURE
SENSOR IN A CAR?
2
The primary job of a fuel pressure sensor or fuel
rail pressure sensor is to monitor the fuel
pressure on the fuel line of a car.
3
Such types of sensors play a vital role in the
performance of an engine which has a fuel
injection system.
4
Pressurized fuel runs through the fuel rail to
reach the combustion chamber through the fuel
injection system.
5
A sudden drop or rise of the pressure on the fuel
rail would adversely affect the operation of an
engine.
6
The engine control unit or ECU uses the data
provided by the fuel rail pressure sensor to
regulate the performance of an engine.
7
Mechanical or electrical malfunctions in such an
important sensor might adversely affect the
performance of the engine.
8
So, signs of a faulty fuel pressure sensor should
not be overlooked.

SIGNS OF A FAILED FUEL RAIL PRESSURE SENSOR
10
The ECU uses data from different types of sensors
including fuel rail pressure sensor to keep the
engine operational.
ILLUMINATION OF CHECK ENGINE LIGHT
11
Malfunctions in different types of sensors used
in the car for various purposes would trigger the
check engine light on the dashboard.
12
Appearance of the check engine light might not
help to detect the root cause behind the
illumination of check engine light, but
illumination of such an important warning sign
should not be ignored.
13
Timely action should be taken to find and fix the
problem in order to prevent any major mechanical
failure.
14
As mentioned earlier, the ECU uses data from the
fuel rail pressure sensor in order to regulate
the fuel injection system.
DIFFICULT TO START THE ENGINE
15
Incorrect data provided by the fuel rail pressure
sensor to the ECU might negatively influence its
ability to regulate the injection of fuel into
the combustion chamber.
16
Unavailability of an adequate amount of fuel
inside the combustion chamber might affect the
ignition process.
17
An engine needs sufficient fuel to generate the
power required to move a vehicle.
POOR PERFORMANCE BY THE ENGINE
18
However, errors in the data provided by the fuel
rail pressure sensor to the ECU would definitely
affect the power output of the engine.
19
Besides, such problems could also increase the
rate of fuel consumption by the engine.
20
BOTTOM LINE
21
Outputs provided by the fuel rail pressure sensor
helps the ECU to keep the engine in working order.
22
Failure of such a sensor could adversely affect
the efficiency of an engine and even could bring
down the vehicle to a halt.
23
So, it is highly recommended to fix the problem
immediately.
