What You Need to Know About P0195 Fuel Rail Pressure Sensor Circuit Intermittent
When your check engine light comes on, it’s important to address the issue immediately before it turns into a more significant problem. One of the codes you may encounter is P0195, which indicates a “fuel rail pressure sensor circuit intermittent” error.
This code can be confusing and frustrating to deal with, but in this article, we’ll break down what it means, its causes, symptoms, and how to fix it.
What is P0195 Fuel Rail Pressure Sensor Circuit Intermittent Code?
P0195 is a diagnostic trouble code (DTC) that is triggered by the powertrain control module (PCM) when it detects an intermittent signal from the fuel rail pressure sensor circuit.
The fuel rail pressure sensor is a critical component of the engine management system that monitors the pressure in the fuel rail and sends signals to the PCM to adjust fuel delivery to the engine.
When this sensor circuit fails to provide consistent signals, it can cause the engine to run poorly, or even stall.
Causes of P0195 Fuel Rail Pressure Sensor Circuit Intermittent Code:
There are several potential causes of the P0195 code, including:
- Faulty fuel rail pressure sensor
- Damaged wiring or connectors in the fuel rail pressure sensor circuit
- Corrosion or dirt buildup on the fuel rail pressure sensor
- Powertrain Control Module (PCM) failure
- Fuel pump failure
- Clogged fuel filter
- Fuel pressure regulator malfunction
- Fuel injector failure
- Low fuel pressure
- Vacuum leaks in the fuel system
Symptoms of P0195 Fuel Rail Pressure Sensor Circuit Intermittent Code:
When the P0195 code is triggered, you may experience several symptoms, which can include:
- Illumination of the check engine light
- Rough or uneven idling
- Stalling or hesitation during acceleration
- Reduced engine power
- Poor fuel economy
- Difficulty starting the engine
- Engine misfires
- Increased exhaust emissions
How to Diagnose P0195 Fuel Rail Pressure Sensor Circuit Intermittent Code:
To diagnose the P0195 code, you will need to use an OBD-II scanner to retrieve the code and then perform a visual inspection of the fuel rail pressure sensor and its circuit.
Check for any signs of damage or corrosion on the wiring, connectors, and the sensor itself.
Next, perform a fuel pressure test to verify that the fuel pressure is within the manufacturer’s specifications. If all the tests come back normal, then the fuel rail pressure sensor itself may be the issue.
How to Fix P0195 Fuel Rail Pressure Sensor Circuit Intermittent Code:
Fixing the P0195 code will depend on the underlying cause. Here are some possible solutions:
- Replace the fuel rail pressure sensor
- Repair any damaged wiring or connectors in the fuel rail pressure sensor circuit
- Clean the fuel rail pressure sensor and its connector
- Replace the Powertrain Control Module (PCM) if necessary
- Replace the fuel pump or fuel pressure regulator if they are malfunctioning
- Replace the fuel filter or fuel injectors if they are clogged or faulty
- Check for vacuum leaks in the fuel system and repair them
P0195 Fuel Rail Pressure Sensor Circuit Intermittent Code is a common problem that can cause a range of symptoms from poor fuel economy to stalling or hesitation during acceleration. By understanding the causes, symptoms, and how to diagnose and fix this code, you can avoid more significant engine problems and keep your vehicle running smoothly.
