Details of the Honda p0087 OBD Code
The fault code P0087 on a Honda indicates low fuel rail pressure.
Code P0087 on a Honda means that the fuel rail pressure is too low.
This code is triggered by the Engine Control Module (ECM) when it detects that the actual fuel pressure is below the desired fuel pressure.
The fuel pressure sensor provides feedback to the ECM regarding the fuel pressure in the system.
If the actual pressure is lower than expected, the ECM will trigger code P0087. This issue can be caused by a faulty fuel pump, clogged fuel filter, fuel pressure regulator malfunction, or a leak in the fuel system.
Mechanic’s Tech Notes
Detailed information on diagnosing and repairing Honda code P0087 related to low fuel rail pressure.
To diagnose and fix OBDII code P0087 on a Honda, start by checking the fuel rail pressure sensor and its wiring for any issues.
Use a voltmeter to test the sensor’s voltage and resistance.
Next, inspect the fuel pump and fuel filter for proper operation and clogs.
Ensure the fuel pressure is within specifications.
If all checks out, consider looking into the fuel pressure regulator and its control circuit.
A scan tool can help monitor fuel pressure readings and system operation.
If no visible issues are found, consider replacing the fuel pressure sensor or regulator as needed.
