Where Is The Fuel Pressure Sensor On A Ram 1500?

Owners of the Dodge Ram 1500 truck have reported issues with the fuel pressure sensor. Some have been unable to locate the sensor, while others have found that the part is discontinued and no longer available from the manufacturer. This has left some drivers with the difficult choice of either finding a used part or driving with the check engine light on. While some have found potential solutions, such as using an OBD reader or purchasing a fuel pressure sensor for a different model year or engine type, it is unclear whether these workarounds are effective for all affected vehicles.

Fuel pressure sensor replacement issues

The fuel pressure sensor in a Ram 1500 monitors the pressure in the fuel rail and reports the reading to the engine control module. If the sensor fails, it can be replaced. However, sometimes the entire fuel rail may need to be replaced, as the sensor is a weak point in the loop that is more prone to damage.

There are a few issues that can arise when replacing the fuel pressure sensor in a Ram 1500. One common issue is that the sensor may not be available from the dealership, as it has been discontinued. In this case, it may be necessary to check local junk yards or find an aftermarket option. Even if the sensor is available, it can be difficult to find one that fits the specific make and model of your Ram 1500, as there are different sensors for different engines and model years.

Another issue that can occur is that the new sensor may not fix the problem. For example, the issue could be with the wiring or another component of the fuel system, rather than the sensor itself. In some cases, the new sensor may even cause the vehicle to shut off after starting, as in the case of a 2016 Ram 1500 where the sensor was reading high fuel pressure.

It is also important to note that the fuel pressure sensor is not part of a maintenance check and is only addressed when it fails. Therefore, it may be necessary to diagnose the issue and replace the sensor as soon as possible to avoid further complications.

Fuel pressure sensor voltage issue

If you're having trouble locating the fuel pressure sensor in your Ram 1500, you may be experiencing a fuel pressure sensor voltage issue. This issue can be caused by a faulty sensor, damaged wiring, or a short circuit.

Diagnosing the Issue:

• Check for Error Codes: Use a diagnostic scan tool to check for error codes related to the fuel pressure sensor. Common codes include P0190, P0191, P0192, P0193, and P0194.
• Inspect the Wiring: Ensure that the wiring connected to the fuel pressure sensor is intact and secure. Look for any signs of damage, corrosion, or loose connections.
• Measure Voltage: Use a digital multimeter to measure the voltage at the sensor connector. You should have 5V on the sensor feed and return circuits and ground on the third circuit. If you're measuring voltage on a disconnected sensor, a reading of 4.78V on the signal wire may indicate a short to voltage.

Addressing the Issue:

• Replace the Sensor: If the sensor is faulty, you will need to replace it. Make sure to purchase a compatible sensor for your specific Ram 1500 model and year.
• Fix Wiring Issues: If the issue is due to damaged or faulty wiring, repair or replace the affected wires. Ensure that all connections are secure and free of corrosion.
• Address Short Circuits: If you suspect a short circuit, carefully inspect the wiring harness and connectors for any signs of damage or abrasion. Repair or replace any affected components.

Preventative Measures:

• Use High-Quality Fuel: Using high-quality fuel from reputable gas stations can help reduce the buildup of pollutants and impurities in the sensor, prolonging its lifespan.
• Regular Maintenance: Regular maintenance of your vehicle, including fuel system and sensor cleaning, can help prevent sensor failure due to wear and tear.

It is important to note that working on fuel systems can be dangerous due to high fuel pressures. Always exercise extreme caution and refer to a qualified mechanic if you are unsure about any procedures.

Fuel tank pressure sensor circuit low

If you're experiencing issues with your Ram 1500 and are seeing a "Fuel Tank Pressure Sensor Circuit Low" error, there are a few things you can try to diagnose and potentially fix the issue.

First, it's important to understand that the fuel tank pressure sensor is typically located on the filler neck and is a 3-wire sensor. You should have 5V on the sensor feed and return circuits and ground on the third circuit.

In some cases, the issue may be as simple as a faulty sensor. You can try replacing the sensor with a new one or a known working used one. Make sure to check the wiring harness for any signs of damage or corrosion as well.

If you're having trouble locating the sensor, it may be helpful to refer to your Ram 1500's service manual or seek assistance from a trusted mechanic.

It's worth noting that some Ram 1500 models may not have a fuel pressure sensor. For example, a user with a 2012 Ram 1500 Sport 5.7L mentioned that their truck did not appear to have a fuel pressure sensor, and none of their scanners showed one. In such cases, you may need to add a sensor that can be integrated into live data scans.

Additionally, if you're experiencing issues with finding replacement parts for your Ram 1500, it may be worth checking with local junk yards or aftermarket suppliers. In some cases, you may need to adapt parts from other models or years that use the same engine or similar components.

Finally, if you're still unable to locate the source of the issue, it may be beneficial to consult with a professional mechanic or a Ram dealership for further assistance. They may have access to additional resources or tools that can help identify and resolve the problem.

Fuel pressure sensor code

The fuel pressure sensor code for the Ram 1500 is P018C or P018B. This code indicates that there may be an issue with the fuel pressure sensor, which is located on the fuel rail. The sensor can be replaced, but it is recommended to take it to a dealer or mechanic to diagnose and fix the issue.

Some people have reported issues with finding the fuel pressure sensor for their Ram 1500, especially for the 2012 and 2013 models. It seems that Mopar, the original equipment manufacturer (OEM), no longer makes the part for these older models. As a result, people have had to look for alternative solutions, such as checking local junk yards or adapting a sensor from a different model.

For the 2014 Ram 1500, the fuel tank pressure sensor is located on the filler neck and is a 3-wire sensor. You should have 5V on the sensor feed and return circuits and ground on the third circuit.

It is important to note that fuel pressure sensors are more common on diesel trucks, as they have two fuel rail pressure sensors. Gasoline trucks typically have a fuel rail pressure regulator instead of a sensor.

Fuel pressure sensor location

The fuel pressure sensor location on a RAM 1500 depends on the model year and engine type. For a 2012 RAM 1500 Sport 5.7L, there may not be a fuel pressure sensor, only a fuel rail pressure regulator. Diesel trucks typically have two fuel rail pressure sensors, but this does not appear to be the case for the RAM 1500. Some other model years, such as the 2013 RAM 1500 with a 4.7 V8 engine, do have a fuel pressure sensor.

For a 2014 RAM 1500 5.7L V8, the fuel tank pressure sensor is located on the filler neck and is a 3-wire sensor. You should have 5V on the sensor feed and return circuits and ground on the third circuit.

For a 2015 RAM 1500, the fuel pressure sensor is located on the passenger side of the engine, close to the firewall on the fuel rail.

It is recommended to use an OBD reader and an app to determine if your truck has a fuel pressure sensor and its location.
