3. Step-by-Step DIY Repair Guide for Honda Odyssey
Connect an OBD-II scan tool and inspect live Mode $01 telemetry for Fuel Rail Pressure (FRP). Compare actual pressure against the ECU's desired setpoint during idle and 2,500 RPM revs. on the Honda Odyssey equipped with 3.5L SOHC VTEC V6 (280HP / 10-Speed Auto).
Verify the low-pressure lift pump is delivering 55–75 PSI to the HPFP using a mechanical fuel pressure gauge on the Schrader valve. on the Honda Odyssey equipped with 3.5L SOHC VTEC V6 (280HP / 10-Speed Auto).
Check the 3-wire FRP sensor harness for 5V reference, ground, and signal voltage (typically 0.5V at key-on to 4.5V at peak pressure). on the Honda Odyssey equipped with 3.5L SOHC VTEC V6 (280HP / 10-Speed Auto).
If low-pressure feed is verified but rail pressure remains under threshold, replace the camshaft-driven HPFP and follower. on the Honda Odyssey equipped with 3.5L SOHC VTEC V6 (280HP / 10-Speed Auto).
Clear DTC memory with scanner, start engine, check for fuel leaks, and drive for 15 minutes to verify fuel pressure monitors pass. on the Honda Odyssey equipped with 3.5L SOHC VTEC V6 (280HP / 10-Speed Auto).

4. Honda Odyssey P0087 FAQs
What causes code P0087 to trigger on a Honda Odyssey?
On the Honda Odyssey (3.5L SOHC VTEC V6 (280HP / 10-Speed Auto)), P0087 is most frequently caused by Failing High-Pressure Fuel Pump (HPFP) or Clogged fuel filter or restricted in-tank low-pressure fuel pump (LPFP).
Where is the OBD-II port located on my Honda Odyssey?
On the Honda Odyssey, the 16-pin DLC diagnostic connector is located Under driver dash, behind small flip cover near hood release. Plug in any standard OBD-II scanner with the ignition in the ON position to read freeze-frame parameters.
Can I safely drive my Honda Odyssey with code P0087?
No. Low fuel pressure causes severe engine hesitation, misfires, stalling at speed, and lean detonation. Given that P0087 carries a Critical severity rating, we advise avoiding heavy towing or aggressive throttle inputs until sensor readings are verified.
