What Does Fuel Rail Pressure Too Low Mean? Error Code P0087 is defined as Fuel Rail/System Pressure Too Low. This indicates a fuel system problem, which is usually a fault within the fuel delivery system.
What causes low fuel rail pressure? Typical causes for low fuel pressure include a dirty fuel filter, weak pump, incorrect tank venting, restricted fuel lines, a clogged pump inlet strainer and faulty electrical control.
How do you fix fuel rail system pressure too low? What repairs can fix the P0087 code
What happens if fuel pressure is too low? Decreased Fuel Pressure
What Does Fuel Rail Pressure Too Low Mean? – Related Questions
What is fuel rail system pressure too low?
Diagnostic Trouble Code (DTC) P0087 stands for “Fuel Rail/System Pressure Too Low.” It may get logged by the PCM when the pressure inside the fuel rail or the fuel system dives below the minimum levels needed to supply the engine with enough fuel to run properly.
How do I know if my fuel rail is bad?
Usually a bad or failing fuel rail sensor will produce a few symptoms that can alert the driver to a potential issue.
Hard starting. One of the first symptoms of a potential problem with the fuel rail sensor is hard starting.
Decrease in power, acceleration and fuel efficiency.
Check Engine Light comes on.
How do you test a fuel rail pressure sensor?
Symptoms of a bad fuel rail pressure sensor
The engine does not start or has a difficult start.
Fuel consumption is increasing.
Check engine light (MIL) is on.
Weak acceleration power.
Engine stalling.
You feel like you’ve lost a lot of engine power.
Will low fuel pressure throw a code?
When your vehicle’s Engine Control M (ECM) records a code of P0087, it means the fuel pressure in the system is below specification. Symptoms of a P0087 diagnostic trouble code may include a misfire because of a lean fuel condition, and the vehicle might run rough or lack power on acceleration.
How much pressure should be in a fuel rail?
For a GM, this pressure is usually set to 58psi (factory fuel pressure in the rail). The vacuum/boost referenced regulator will help to change the pressure in the rail based on the pressure in the manifold. When an engine is idling, it may be pulling 20 inHg of vacuum, which translates to roughly 10psi.
Can you drive with low fuel pressure?
If you put too little fuel then your engine will run lean which is probably ok, but it will run hotter. This may damage your valves or pistons, requiring an engine rebuild. But yes the engine will probably run and feel ok. Sure as long as you still have good fuel pressure.
Can a clogged fuel filter cause low fuel pressure?
A clogged fuel filter causes low fuel pressure that results in a lean fuel condition and engine misfire. This can result in poor fuel mileage, rough idling and possibly cause the check engine light to come on.
How do I know if my fuel filter is clogged?
Signs Of A Clogged Fuel Filter
Trouble Starting the Engine. The most common sign of a clogged fuel filter is trouble starting the car, since it depletes the oil supply going to the engine.
Issues Accelerating.
Frequent Idling and Sputtering.
Strong Odors.
Engine Misfires/Low Performance.
When to Replace the Fuel Filter.
Will a bad fuel pump throw a check engine light?
A weak fuel pump may throw off your car’s air/fuel ratio, causing the engine control module (ECM) to turn on the check engine light. In some cases, pump electrical issues may trigger the light as well.
Does AutoZone check fuel pressure?
AutoZone makes checking fuel pressure easier than ever. Get a fuel pressure test kit and check the fuel pump and fuel system on your ride today.
How do you check fuel pressure while driving?
Check your fuel pressure when you first start your engine then check it again after the engine compartment has warmed-up. If it reads lower when hot as compared to cold, with the engine running pour some cold water over the gauge and check the pressure.

Can you drive with a bad fuel rail pressure sensor?
It’s going to be impossible to get your car to continue running for more than a few seconds at a time. Once you reach this point, you should not continue to drive your car around with a bad fuel rail pressure sensor in it.
How much does it cost to replace a fuel rail pressure sensor?
On average, expect to pay between $200 and $340 total for a fuel rail pressure sensor replacement. Parts alone will set you back about $60 to $100 and the labor cost to replace the sensor will cost between $140 and $240.
Will a clogged fuel filter throw a code?
Check engine light comes on: While the fuel filter is not directly connected to the engine computer, a blocked fuel filter can trigger a variety of trouble codes, including: Low fuel pressure. Lean running condition.
