Direct injection, unlike port injection, injects fuel directly into the cylinder and, depending on driver demand, may inject fuel during the intake stroke or near the end of the compression stroke, or even during the power stroke. Additionally, new fuel injectors were prescribed to address this problem. Make sure you hire a qualified mechanics for a more thorough diagnosis and professional repairs. Most vehicles simply required a new cam follower, though some required a new camshaft. Some vehicles may not be equipped with an external fuel filter. Turn off and turn on ignitation will help always. In most cases, the cam follower would turn concave, sometimes blowing off the face and damaging the camshaft and the fuel pump.
Then turn your attention to fuel pressure itself. Direct fuel injection systems may or may not be paired with port fuel injection systems, but one thing they all share is the presence of two fuel pumps. . Is the pressure in range at 600 and 1800 rpm? Hello, I have an 2010 Audi S5 4. Maybe the fuel pressure check is the way to go? Test drive the truck to see if the code sets. Faruk- Please provide information about your vehicle: year, make, model, and engine? These are generally replaced as one unit since the gas tank must be removed from the vehicle in most cases.
This error code is a manufacturer-specific trouble code, meaning it does not apply to all vehicles makes. The underlying porblems have been various but solved by the garage so no probs for a while. Missfire all over the board, which it would be as rail effects all 8. If the level was under ¼ tank or 25% , fuel sloshing in the tank could be the cause of aerated fuel that could cause this code. Specification of the definition, troubleshooting, and repairs still vary from one make and model to another. Definition Error Code P1093 is set because the fuel rail pressure is low. Some plastic fuel lines are especially prone to kinking and collapse, obstructing fuel flow from the low-pressure pump to the high-pressure pump.
Also, its pump speed can vary to deliver rail at variable rate, rather than constantly running the fuel pump and regulating the pressure through pressure regulator, returning fuel back to the tank. Once the engine shuts down, leave the key on for five minutes. External fuel tank damage could impact the fuel sender inside the tank, leading to poor fuel intake by the low-pressure fuel pump. Rarely, the fuel pump plunger was affected, requiring replacement of the fuel pump. If comparing to before I replaced the sensor and fuel filter, I would feel the car begging for fuel 100% of the time.
Are there any cylinders above 70% or below -70%? Hello, I have that fault code P0087, in a Kia Sorento 2. This code is similar to P0088. An advanced scanner is also needed to monitor fuel pressure sensor data. This error code is very similar to Error Code P0088. Problem did not get fixed. Both of these readings are needed to test the fuel pressure sensor. Make sure you actually have fuel in the tank and there are no fuel leaks.
Is there a chassis fuel system issue? Clear codes and road test to verify complaint. In agreement Then I will have to go to a diesel service center to measure the actual parameters of fuel pressure, even if the scanner has become a service device, as well as a cleaning in the tank and was with many apparently cotton fabrics , there I do not know what happened before as this contamination arrived, thank you Benjamin. How to Fix The diagnosis above can offer quick fix for this error code. A qualified mechanic should be contacted and repairs should be done to get the vehicle safely back onto the road. Inspect for damage including fuel, water corrosion or bent terminals. How to Fix Since a blocked fuel filter is the common cause of this problem, then cleaning or replacing your fuel filter can fix the problem. A failed fuel pump can cause the engine to die while driving, which may result to serious problems for the driver.
I originally started with feeling like i was in limp mode but even in limp mode barely getting power. This will help a lot. Likely need someone to do a pressure test to determine the source of the leak to repair it. Then, technicians will proceed to check leakage in the fuel system. A problem usually caused by the fuel pump, fuel supply pipe blockage, fuel pressure regulator or mechanical fault. Once they fill up, they practically block all fuel flow. If code does not set, release the vehicle.
The fuel rail comes with a sensor that monitors its fuel pressure and change the pump speed accordingly. If code does not become active during road test, release the truck. What causes the P0087 code? In spite of fuel purity standards, contamination can build up over time, or experienced on at least few occasions, a bad batch of super-contaminated fuel can clog up a fuel filter in just a few minutes. If the fuel pump is failing or the fuel filter becomes completely clogged, this may cause the engine to die while driving resulting in serious issues for the driver. These vehicles will only be equipped with the fuel screen that is attached to the fuel pump. How serious is the P0087 code? To make such injection possible, particularly when injecting at the end of compression or during the power stroke, high pressure is required, and the typical high-pressure fuel injection system usually runs from 200 psi to over 3,000 psi, whereas common port fuel-injection systems usually run between just 10 psi and 65 psi.
Car started but after a very long crank. So please help me… Seems to me the fuel pressure is bleeding down after the engine is shut down, which is why it only sets the code after sitting overnight. It turned out to be the high pressure fuel pump. If the code becomes active during the road test with over ¼ tank or 25% of fuel, Go to step 4. Might require factory special tools, because the high-pressure system is dangerous.
From here on, you may also want to perform further diagnosis for the high pressure fuel system using special tools and steps. At this point, you may not be able to perform any further diagnosis, as the high-pressure fuel system requires special tools and procedures. Other repairs, of course, include repairing or replacing components to prevent fuel system leakage. Does the air flow fluctuate before or after the fuel pressure problem? I deleted the codes and than had Cyd 1,3 and 8. If code sets, Go to step 2. This allows us to check fuel pressure at the fuel rail and then use the scan tool to check what the fuel pressure sensor is reading.
