How to Fix P115A Code 6.0 Powerstroke Engine?

What does the code P115A code 6.0 Powerstroke engine mean? It means a low fuel level has forced limited power of the vehicle.  The 6.0L Powerstroke engines represented a considerable step up for Ford trucks. However, they have been plagued with problems since their release.

In this article, we’ll walk you through the most common causes and symptoms of code P115A on 6.0 Powerstroke engines to get your truck back up and running as quickly as possible. While the fixes may be daunting, following this guide can help your vehicle rerun like new.

P115A Code 6.0 Powerstroke

Most of the time, the communication system between the vehicle’s center console and PCM sends information about how much gas is in the tank. Suppose the powertrain control module receives too much low fuel level input information from the instrument cluster. In that case, the powertrain control module limits your vehicle’s fuel rail pressure and sets the error code P115A. 

This error code is set to try and avert injector damage. A low or empty fuel tank is the most common reason behind the P115A code on 6.0L Powerstroke.

Reasons Behind The P115A Error Code On The 6.0 Powerstroke EngineSymptoms You may Face
Low or empty fuel tankVehicle won’t start, the engine stalls when idling or at low speeds, and the engine may also run rough and hesitate when accelerating
Dirty fuel filterThe vehicle emits excessive smoke, loss of power, and hard starts
Faulty fuel level sensorThe dashboard lights went out, the gauges stopped working, misfires and increased emissions
The fuel level sensor circuit has a poor electrical connectionThe vehicle misfires, an erratic fuel gauge reading, and the engine shuts down unexpectedly

Now, let’s discuss these symptoms, reasons, and solutions elaborately.

Low Or Empty Fuel Tank

If you’re seeing the P115A error code on your 6.0 Powerstroke engine, it’s likely because the fuel tank is low or empty. The vehicle stopping when it is decelerating or traveling at cruising velocities represents the most prevalent sign of this condition. The engine may also stutter and jerk when you accelerate.

Sometimes, your 2006 Ford F-350 truck won’t start, and you will get the P115A error code. This problem happens when you have a low or empty fuel tank. In this case, you need to refill your fuel tank to solve the P115A code on 6.0L Powerstroke issue.

Dirty Fuel Filter

The P115A code is associated with a dirty fuel filter. The fuel filter mainly removes dirt or debris from fuel. Over time, however, the filter can become clogged with dirt and grime, preventing the engine from getting the clean fuel it needs to run correctly.

Some owners of the 2007 Ford F-250 have complained that their trucks emit excessive smoke. They will get a P115A error code, and their trucks won’t start. This problem happens because of a dirty fuel filter. Generally, after driving 25000 miles, the truck’s fuel filter becomes dirty. 

Symptoms of a dirty fuel filter include a loss of power, decreased fuel economy, and hard starts. There is also a possibility that the engine will stall completely or operate erratically. If you notice any of these symptoms, it’s essential to check the fuel filter for the P115A code on 6.0L Powerstroke and clean it if necessary.

All those owners who have complained have driven their trucks more than 25000 miles, like 37000 miles. In order to fix this problem, you will need to clear the clogged fuel filter. If the problem is still not solved, you must replace the fuel filter.

Faulty Fuel Level Sensor

A faulty fuel level sensor is one of the most common reasons behind the 6.0 Powerstroke P115A engine. The sensor itself is located in the fuel tank, and its purpose is to measure the amount of fuel in the tank. If the sensor isn’t working correctly, it can cause the engine to run lean, leading to several problems.

We have found out that the 2005 Ford F-250 trucks sometimes have electrical issues like the dashboard lights going out and the gauges stopping working. In such cases, you will also see the P115A error code in the truck.

The light on the dashboard is the more prevalent indicator of a malfunctioning gasoline pressure gauge. Other symptoms can include reduced fuel economy, misfires, and increased emissions. If you are also facing this problem, then the reason behind it is a faulty fuel level sensor. To solve this problem, you must replace the defective fuel level sensor.

The Fuel Level Sensor Circuit Has A Poor Electrical Connection

This is another common reason behind the P115A code on the 6.0L Ford Powerstroke engine. Many people complained that their trucks misfire. They have also complained that their trucks jerk. Other symptoms of this problem include an erratic fuel gauge reading and the engine shutting down unexpectedly.

So, in this case, the solution is to fix the electrical connection, so it is secure and free of corrosion. This can be done by cleaning the terminals or replacing the connector entirely. Once the connection is fixed, the problem should be resolved, and the engine will run smoothly again.

How to fix code P115A on 6.0L Powerstroke?

If you have a 6.0L Powerstroke with code P115A, there are a few things you can do to try and fix the problem. Initially, verify that the coolant storage is filled. If it is insufficient, add more coolant and watch for the error message to disappear. The next step is checking the ECT sensor to see if the coolant level is acceptable. This sensor can sometimes get dirty and cause issues. Check to see if the error code is removed after cleaning the sensor. You may need to consider replacing the sensor if the error code does not go.
