Code P0087 can be a bit of a mystery for drivers. However, don’t worry! We’re here to help clear up some of that confusion and provide resources so you can get your car back on the road.

What Does Code P0087 Mean?

Code P0087 is a Malfunction Indicator Lamp (MIL) code. The Powertrain Control Module (PCM) has detected a problem with the Engine Coolant Temperature (ECT) sensor.

The ECT sensor measures the temperature of the engine coolant and sends this information to the PCM. The PCM uses this information to control the engine cooling system. If there is a problem with the ECT sensor, it can cause the engine to overheat.

Although Code P0087 is considered a “minor” code, it’s still important to diagnose and repair it as soon as possible to avoid further damage or potential safety hazards.

Symptoms of Code P0087

The symptoms of this code can vary depending on the severity of the issue, but they usually include the following.

Check Engine Light On The Dashboard

The check engine light on your dashboard is the most common symptom of code P0087. This code means that the fuel pressure is too low.

After this light is on, you may not be able to pass an emissions inspection because a low fuel pressure can cause your car to emit higher pollution levels. If you ignore checking the engine light for too long, it could damage your fuel injectors or other engine parts.

Vehicle May Run Poorly

Code P0087 is a fault code that indicates that the fuel system has too little or no pressure. Low fuel pressure can lead to poor combustion and reduced power, so the vehicle will often run poorly. In extreme cases, the engine may even stall.

A few different things can cause your vehicle to run poorly, such as:

  • Your fuel pump is not working correctly (If your fuel pump is not working correctly, the car may not be able to get enough fuel to the engine)
  • Your fuel injectors are dirty or clogged.
  • Your oxygen sensor may be damaged or not functioning properly.

Loss of Engine Power

When the P0087 code is present, the engine doesn’t produce enough power to meet its required load. It can cause problems, from decreased acceleration to a complete loss of power.

If there is time is getting your vehicle fixed, you can take the following measures to ensure your safety.

  • Check the fuel pressure and make sure it’s within the normal range. If it’s not, that could be the cause of the problem.
  • Check for any leaks in the fuel tank.
  • If there are any, they need to be fixed before the engine runs properly.

Engine Misfire

Engine Misfire can be caused by code P0087 in some cases. But it’s usually a symptom of an ignition or fuel system problem. It can happen for several reasons, but usually, there’s not enough fuel reaching the engine.

If your engine is misfiring, it’s important to diagnose it as soon as possible. Otherwise, you could end up damaging your engine.

Bad Fuel Economy

Decreased fuel economy is a frustrating symptom of code P0087, but you can usually track down and fix the problem with a little detective work.

  • The first thing you should do is check the FRP sensor. If it’s faulty, replace it.
  • If the problem persists after replacing the sensor, the Sensor Circuit may have an electrical problem.
  • Check all of the wiring and connections to the FRP sensor, and if everything looks good, try replacing the sensor itself.
  • The fuel pressure regulator is to blame if you’re still having trouble after replacing the sensor. It is a more serious problem and will require professional help to fix.

What Causes DTC P0087?

Here are several causes that are responsible for DTC P0087.

Clogged Fuel Screen or Filter

A clogged fuel screen or filter can cause the code P0087 to be stored in your vehicle’s computer. This code is set when the engine’s control module (ECM) detects that the fuel pressure is too low or a restriction in the fuel flow.

When the fuel pressure is too low, it can cause various problems, including losing power, stalling, and even engine failure. If your vehicle is experiencing these problems, it’s important to have the clogged fuel screen or filter cleaned or replaced ASAP.

Bad Fuel Pump

Bad fuel pumps can cause problems for your car, but one of the most common is a code P0087. This code indicates something wrong with the fuel pump’s pressure regulator.

A few things can cause a bad fuel pump, including a failed motor or wiring problem. But the most common cause is a clogged filter. When the filter gets clogged, it doesn’t allow enough fuel to flow through. This means that the fuel pump has to work harder to deliver the same amount of fuel, eventually leading to failure.

Restricted Fuel Line

It’s important to know how your car’s fuel system works and what can cause problems. One of the most important parts of the fuel system is the fuel line. The fuel line is responsible for carrying gasoline from the gas tank to the engine. When the fuel line becomes restricted, it can cause problems in the fuel system, including a code P0087.

Fuel Pressure Sensor Improperly Reading

When the fuel pressure sensor reads an improper pressure, it can set off the check engine light and trigger a code P0087.

Common causes for this to happen are:

  • A loose or damaged gas cap
  • A faulty fuel pump
  • A blockage in fuel lines

If the code is triggered, it’s important to have the vehicle checked out by a mechanic to find and fix the root cause. Failing to do so can result in poor fuel economy and even engine damage.

Is Diagnostic Code P0087 Serious?

Yes, sometimes it can be serious. P0087 is an engine code that indicates a problem with the fuel pump, pressure, delivery, or wiring. If the fuel pump isn’t working properly, your car won’t be able to start, and you could end up stranded on the side of the road.

But sometimes, P0087 is not a serious diagnostic code. It’s generally just an indication that there’s something wrong with your fuel system—for example, a leaky fuel injector. However, if you’re experiencing symptoms, it’s best to get it checked out by a mechanic to ensure there’s no underlying issue.

How to Diagnose and Repair Code P0087?

  • Check the fuel pressure at the rail. If it’s below 60 psi, there could be a problem with your fuel pump or injectors. If the pressure is within specs, there might be a blockage in your fuel system. Try clearing any debris from the line and see if that solves the problem.
  • Check the wiring and connector for the ECT sensor. Ensure that they are connected properly and that there is no damage to the wiring.
  • If the wiring and connector are good, you’ll need to test the ECT sensor. To test the ECT sensor, you’ll need a multimeter. Check the resistance of the sensor at different temperatures. If the resistance doesn’t change or changes erratically, then the sensor is most likely damaged and will need to be replaced.

Tools Needed to Diagnose Code P0087

You’ll need to use some specific tools to diagnose Code P0087. The most important tool is a scanner or diagnostic tool to read and interpret OBD-II codes. Other tools that may be necessary include

  • Digital voltmeter
  • A test light
  • A vacuum gauge.
  • Manual Fuel Pressure Tester

A failing fuel pump is one of the most common causes of throwing a P0087 code. Therefore, a manual fuel pressure tester is a necessary tool to check the fuel pressure in your system.

  • OBDII Scan Tool

In some cases, a mechanic may be able to use a handheld diagnostic tool or even a code reader to determine the problem. However, an OBDII scan tool can provide more information about the issue and may be necessary in some cases.

How Do I Fix Code P0087?

If you see the code P0087 pop up on your car’s dashboard, don’t panic! There are several things you can do to try and fix it.

  • Clean the air filter. You can usually find this filter near the front of the engine, and it’s typically easy to remove and replace.
  • Check the air intake hose. This hose carries air from the air filter to the engine, and if it’s blocked or damaged, it can cause the code P0087 to appear.
  • Check if the fuel filter is dirty or clogged. If it is, remove it and soak it in a solution of degreaser and water. Once soaked, rinse it off with clean water and then dry it completely before reinstalling it.

If neither of these solutions works, you may need to take your car to a mechanic or dealership to have it checked out. They can run some tests to diagnose the problem and figure out the best way to fix it.
