Fix P0087 Code On 6.7 Powerstroke: Fuel Rail Pressure Is Low

Various diagnostic trouble codes are set by the Powertrain Control Module (PCM) for multiple reasons. Some of these codes are minor and some are considered serious.

The p0087 code on the 6.7 Powerstroke means “fuel rail/system pressure is low.” In this way, when there is low pressure in the fuel rail/system, the code p0087 will be logged. It can be a result of a faulty fuel filter or pump. So, anyone can fix this code by replacing the damaged parts of the fuel rail. 

There are also some reasons for this code and the ways to solve it. But what are they, and how much does it cost to fix these issues? To get all the necessary information you must know, let’s dive into the article below.

What Does p0087 Code Mean On 6.7 powerstroke?

P0087 on the 6.7 Powerstroke is an OBD-2 diagnostic trouble code which means fuel rail or fuel system pressure is too low. The code is logged when the PCM detects low fuel pressure at the fuel pressure sensor of the Powerstroke 6.7.

The fuel pressure sensor on the fuel system keeps measuring the fuel pressure. When the pressure falls below the minimum levels required to run the engine, the pressure sensor gives instructions to the PCM to set the code. 

Here is a breakdown of the code p0087 on what each digit means:

  • P = powertrain, which includes the engine, transmission, and other system components.
  • 0 = a generic code also known as SAE.
  • 0 = Fuel and air metering controls
  • 87 = Defines the exact problem ( in this case, low fuel rail/system pressure)

How Serious Is Code p0087 On 6.7 powerstroke?

The diagnostic trouble code p0087 on the Powerstroke 6.7 can create many serious issues for the car and the driver as well. More specifically, when the code is set, the car starts misfiring or is hard to start. It can also cause serious drivability problems. 

Besides, if the fuel filter is clogged or the fuel pump is damaged, it can damage the engine further. In simple terms, this trouble code can make your car dead. So, the code p0087 is serious enough and should be diagnosed asap. 

What Causes Code P0087 On The 6.7 Powerstroke?

How To Fix The p0087 Code On The 6.7 Powerstroke?

As there are many reasons for the code p0087 on 6.7 Powerstroke, you should fix it by diagnosing each reason and solving it as required. 

However, we recommend you get help from a professional technician in your area if you are not completely comfortable doing the job yourself. But if you are, here’s what you’ll do:

1. Replace the Fuel Filter

Start by checking the fuel filter. If you find the fuel filter is not working, it’s better to replace it. Here are steps to replace a fuel filter:

Step 1: Relieve the Fuel Pressure

First you have to remove pressure from the fuel line. So remove your fuel pump fuse or relay. Start your engine and allow it to idle until it stalls. This may trigger your check engine light. 

Once it stalls, crank the engine for about five seconds to release fuel pressure. This should relieve most of the pressure, but there could still be a little fuel that will squirt or leak when you detach the filter. 

Step 2: Perform Some Preparatory Work 

Turn the ignition back to the off position. Now disconnect the battery ground cable marked with a minus sign. Set it to the site and make sure that it isn’t touching anything metal. Raising and supporting your vehicle. 

In this case, have a drain pan of some kind in place under the filter to catch any fuel that is left in the line or filter when you detach them. It’s also a good idea to have some rags handy. 

Step 3: Dispose of the Old Fuel Filter

Once you’ve located the filter, use a screwdriver to detach the clips from the line. Be careful not to kink your fuel lines as you detach the fuel filter. It can cause leaks. Then disconnect the fuel line fittings and remove the filter. 

Step 4: Install the New Fuel Filter

ln a new filter, the direction of fuel flow will always be toward the front of the vehicle. Now you install the new fuel filter.

Use the clips that come with the filter to attach it to the fuel line. And secure the clamp to hold it in place. 

Reinstall the fuel pump relay or fuse and reattach the group cable. Turn your ignition to the on position for a few seconds, and turn it off again. This will bring the fuel pressure back. So, finally you’re done. 

2. Replace the Damaged Fuel Lines

If the fuel filter is fine, it may be a problem with the fuel lines. So, visually inspect the line. If you find the fuel line is faulty, replace the damaged part of the line. To do so, here are the steps to follow: 

First, cut the damaged section of the fuel line. Now measure the inner diameter of the fuel line and choose a sleeve of the appropriate size. Insert a sleeve into the fuel line. Now measure the outer diameter of the line and choose a rubber hose of the right size. 

Then cut the required length of the rubber hose. Now insert the fuel line into the hose. To do so, place ABA mini clamps over the sleeve and tighten. Now insert the connector onto the other side of the hose and tighten it with an ABA mini clamp. Connect the repaired fuel line to the other end of the spigot. 

3. Change the Faulty Fuel Pump

If the p0087 code is still on your 6.7 Powerstroke after replacing the fuel line, it may be a problem with the fuel pump. Here’s the process to follow to change the pump:

Step 1: Locate the fuel pump

First, locate the fuel pump on your 6.7 Powerstroke. The fuel pump is usually located in the fuel tank.  

Step 2: Remove the fuel pump

Once located, detach the old fuel pump. To do so, relieve the fuel pressure. Then disconnect the negative wire. Now check if there’s any fuel in the fuel tank. If so, drain the fuel as much as possible. 

After that, detach the rubber hose and the electrical connections. Then remove all the straps holding the pump to the tank and lower the tank. While doing this, make sure to support the tank with a jack and a wood block. 

Now disconnect the fuel lines connected to the module and remove the pump. 

Step 3: Install the new fuel pump

Once you remove the old fuel pump, compare it with the replacement fuel pump to confirm that it is the right size. Now, all you need to do is just reverse the process. 

In this way, install the new fuel pump and reconnect the fuel lines to the pump. Now reconnect the hoses and electrical connectors. Rejoin the negative battery cable and fill the tank with fuel. Then check if the trouble code is fixed. 

4. Remove the Faulty Fuel Pressure Sensor and Replace It 

When the code p0087 appears on Powerstroke 6.7, diagnose if the sensor is working. If it doesn’t work, it must be replaced. Here are the steps to go through:

Step 1: Look for the Fuel Pressure Sensor

Generally, a fuel pressure sensor is located inside the fuel tank. To be more sure, check out the manufacturer’s manual of your 6.7 Powerstroke. 

Step 2: Remove the Faulty Fuel Pressure Sensor

Now remove the bad fuel pressure sensor. For doing this, start by disconnecting the battery from the car. Then remove the fuel tank and take out the fuel pump. Now locate the sensor and take it out of the fuel pump. 

Step 3: Impose the New Sensor

Once you detach the faulty fuel pressure sensor, install the new one. Then reassemble the fuel pump and the fuel tank. Finally, reattach the battery and recheck if the sensor works properly. 

5. Replace the Faulty PCM 

If you find all the possible parts of your Powerstroke 6.7 are fine, your car’s PCM may be damaged. To be sure, check fuel pressure and see if it matches with the reading the PCM is showing. 

If the PCM detects a fault, it means it needs to be replaced. Here is the procedure from first to last:

Step 1: Disconnect the battery and locate the PCM

First of all, disconnect the car’s battery and locate the PCM of your 6.7 Powerstroke. The PCM is usually mounted in the engine compartment. Now disconnect the electrical connections in the car.

Step 2: Remove the bad PCM 

After that, take out the old PCM. To do so, remove all the bolts that hold the part in the right place. You can do it using a screwdriver or socket wrench. 

Step 3: Install the new PCM

Install the new one after removing the old one and tightening the bolts. Then rejoin the electrical connections and the battery connection. Now check if the code is removed, and with this, you have just finished your job.
