How about some back-pressure in the feed and return lines, blocking the either end off and see? Filtro cambiado y sensor de presión también. Traced wiring back and found issue to the fuse that controls that valve. Me sale fallo P0087 es intermitente nada más circulando en bajas revoluciones del motor 1500-2000 también parado pisar el pedal de aceleración y soltar se apaga el motor y salta este fallo después quitando el llave y volver arrancar no sale nada. In later car models, the car's computer can usually keep the vehicle running, but the engine warning light on the dashboard goes on to warn the driver. P0087 can lead to serious drivability issues. A failed fuel pump can cause the engine to die while driving, which may result to serious problems for the driver.
The only way to see this is to perform a thorough visual inspection. These are generally replaced as one unit since the gas tank must be removed from the vehicle in most cases. But, strange things have happened. Might require factory special tools, because the high-pressure system is dangerous. If comparing to before I replaced the sensor and fuel filter, I would feel the car begging for fuel 100% of the time. De esta forma la bomba de combustible no necesita trabajar de manera constante, además de regular la presión de combustible devolviendolo al tanque. This code is similar to P0088.
Part 06E 130 757 C. When is the code detected? Fuel filter has been ordered for stand-by replacement. In some applications the pressure regulator is located on the fuel rail and operated by a spring with vacuum assistance obtained from the inlet manifold. This eliminates the pressure regulator integrated into the filter and sends delivery-pump pressure straight to the fuel rail. Check Low Fuel Pressure System for Leaks. Oh the work done was just an oil change, fuel filter change Did you closely inspect the old Fuel filter , housing and fuel for any metal flakes or sign of it before ditching for the new one.
There shouldn't be any other voltage there! Yep, couldn't fix it, not even with a Heli-Coil or Time-Sert. Step 1 Begin the diagnostic procedure by recording all stored fault codes and available freeze frame data. This indicates a fuel system problem, which is usually a fault within the fuel delivery system. Check the Fuel Quantity supplied by the Fuel Pump G6. In practice, it is more common for defective fuel pressure sensors to set low fuel pressure related codes.
Also I would like to tell you that I already changed all 6 injectores i swear! 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. ? Now don't ask yourself; What should you do with P0087 code? Start the engine, and monitor the actual pressure in the fuel system via the gauge, and the scanner. The cut-away drawing below shows the typical construction of a fuel rail-mounted fuel pressure regulator. How do you troubleshoot code P0088? Tampoco olvidar revisar o reemplazar el filtro de línea. Except that I received the code at the same time that the pump went out, not as an intermittent fault. Does the air flow fluctuate before or after the fuel pressure problem? Matt, I don't think there should be reference voltage there or residual. I have a feeling it's going to be a rocky road , check the fuel pressure going to injectors coming outa the pump.
If nothing abnormal is found during the visual inspection, than a mechanical fuel pressure tester will be used to check fuel pressure at the fuel rail. At this point, you may not be able to perform any further diagnosis, as the high-pressure fuel system requires special tools and procedures. It could also be the pressure control valve which is part of the fuel rail assembly, but this part costs more and it is harder to replace. 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. So you have to refer to the factory legends to learn the identification symbols and then refer back to circuit diagrams to find the splice and ground locations. Though scan tools will tell us what the fuel pressure sensor reading is, these may not be accurate if the fuel pressure sensor is faulty. I still don't know what it was that got it to act this way.
Consult the manual on the correct procedure to remove the pump, and to replace the regulator. Step 2 Sine code P0088 indicates an excessive fuel pressure the problem is unlikely to be caused by wiring issues, unless the fuel pressure regulator is electrically operated. Make sure you hire a qualified mechanics for a more thorough diagnosis and professional repairs. Esta falla se puede presentar por que el sensor de presión de combustible pierde la información de la presión. It may just come to that. The symptoms listed above make the vehicle unsafe to drive, so you should consult a mechanic as soon as possible before getting back on the road. Run basic settings 103 to reset system Yes.
This obviously only applies to vehicles that can still be driven. If the difference between reported and actual is greater than 73-psi, check the wiring to the fuel pressure sensor for chafing or faults. What repairs can fix the P0088 code? Well-known on diesel engines, high-pressure fuel injection systems have made their way to gasoline engines, specifically those equipped with direct injection systems. I just had some work done this weekend by a reputable senior member of this forum and he kindly ran the code reader on the car. Need help with a P0087 code? In the unlikely event that the code persists, it is possible that there is an intermittent fault present, which may have to be allowed to worsen before an accurate diagnosis and repair can be made. An advanced scanner is also needed to monitor fuel pressure sensor data.
And have not been able to duplicate it again. I've seen this happen on fuel delivery lines and hydraulic system hoses. 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. May just be dropping a Fuel delivery pump into this next. Maybe can dead-head the fuel return line near the filter and get the supply volume to increase on the rail side. Come to find out they really effed this truck up, and we still repairing various wiring from that swap even today.
