What causes fuel rail system pressure too low?
Potential reasons include: Fuel Filter issues. A crimp or restriction in the fuel supply line. A bad or failing fuel pump or fuel pump control module.
What does fuel rail low pressure mean?
Trouble Code: P0087 Fuel Rail/System Pressure – Too Low This means the fuel pump can vary its speed to deliver fuel as needed, rather than running constantly at a steady speed. There is a sensor on the fuel rail that monitors fuel pressure and determines if the vehicle needs more or less fuel.
Can a fuel filter cause 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.
What does the p0087 DTC mean on a fuel pump?
The PCM (powertrain control module) or ECM (engine control module) has detected that fuel pressure is below specification for the supply commanded to the fuel pump driver module or fuel pump assembly. Symptoms of a P0087 DTC may include:
What does ODB II code p0087 mean?
When going up grade pulling fifth wheel camper, check engine light will occassionally luminate. ODB II code is p0087. DIC shows “change fuel filter” or engine power is reduced. Fuel filter changed 5k miles ago.
What does the code p0087 mean on a Chevy Silverado?
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.
