What Does Code P0087 Mean On Cummins? (How to Fix It)

Your vehicles with a cummin engine may face many issues such as fuel system error, fuel pressure problems, or supply pipe issues. Whatever the problem is, you must find a proper solution, right? Then, a diagnostic trouble code will help you find the exact issue immensely.

The code p0087 on Cummins represents the issue related to the fuel delivery process of your pickup trucks. There are many factors responsible for this issue. Among them, supply pipe blockage, mechanical issues, problems in pressure regulation, etc., are common.

However, this article will let you know how serious the code p0087 is for the automobile with a cummin engine, what to do in this situation, the cost of repair, and many more associated crucial things. So, without wasting any more time, let’s start to learn.

What Does P0087 Means For Cummins?

The fuel sensor of your vehicle determines how much fuel the engine needs. Now, if you notice the code p0087, it means the engine is facing fuel pressure issues. However, let’s look at the breakdown of the code p0087.

  • P= Powertrain, a system that helps the vehicle to move forward.
  • 0= a generic (SEA) number
  • 0= Fuel and air metering
  • 87= Specific fault index (In our case, this represents fuel system pressure too low )

The vehicle’s fuel pressure can be raised by PCM whenever it needs more power. But when the fuel rail pressure remains too low, your Cummin engine vehicle faces an issue supplying the fuel. Hence, the vehicle’s engine will not get the necessary fuel.

Consequently, the PCM of your vehicle will log the code p0087. However, the Society of Automotive Engineers (SAE) has specified this p0087 code to trigger the described issue.
