Code P0087 Lexus Description

With a cold engine, the internal pressure of the common rail is regulated by the Pressure Control Valve of the common rail assembly. With a warm engine, it is regulated by the suction control valve of the fuel supply pump. When the engine is running with a light load, it is regulated by both the pressure control valve and the suction control valve. Based on signals from the Engine Control Module (ECM), the pressure control valve opens when sudden deceleration occurs to prevent the fuel pressure from becoming too high. The Diagnostic Trouble Code (DTC) will set when the Engine Control Module has determined that the fuel rail pressure is too low for a specific engine RPM.
