Code P0087 Chevrolet Description

The Engine Control Module (ECM) uses the Fuel Rail Pressure (FRP) Sensor to determine fuel pressure to the fuel injectors. This is then compared to the calculated target fuel pressure as determined by the ECM. The ECM adjusts the FRP by modulating the duty cycle of the control driver of the fuel pressure regulator. Injector pulse duration is determined by the measured rail pressure and the target injection fuel into each cylinder. If a sensor circuit malfunction is detected, or the commanded fuel injection pump flow is not within the proper range for a given engine load and speed, the Diagnostic Trouble Code (DTC) will be set.

  • I have 07 GMC Sierra LBZ Duramax in which I reset the valves .012 and recheck with a .013 no go
    done this twice and I'm having a hard time starting it but I've learn to start it by unplugging the fuel pressure sensor then it starts with at idle about 7000 rpm then it jump up 9000 then it surges
    between 7-9 rpms I'm thinking that it the FRP sensor
