The 5th generation CR-V (2018-2022) is included in Honda's fuel pump recall 23V-858, which covers about 2.49 million U.S. vehicles. Denso-manufactured fuel pump impellers were made with improperly molded low-density material that swells and deforms under fuel exposure, interfering with the pump housing and causing the pump to slow or fail. Engine stalling at highway speeds has caused collisions. This is the same recall affecting the 2018-2022 Accord, Passport, Pilot, and other Honda models. Honda expanded the recall multiple times as the scope widened to cover additional production dates.

Common Symptoms

  • Difficulty starting - engine cranks longer than normal before starting
  • Rough idle on first start of day
  • Engine hesitation or stumbling under acceleration
  • Engine stalling while driving at any speed
  • Check engine light with P0087 (fuel pressure too low)
  • Engine cranks but does not start (complete pump failure)

How to Fix

Frequently asked questions

What does P0230 mean?

P0230 stands for "Fuel Pump Primary Circuit Malfunction." P0230 means the engine computer detected a fault in the fuel pump primary circuit — the control side that switches the fuel pump (or its relay) on and off. The PCM energizes this circuit to run the electric fuel pump that delivers fuel to the engine; if it sees voltage that is too high, too low, or out of expected range, it sets this code. Because the pump may not run correctly, the engine can crank without starting, stall, lose power, or hesitate. This is a circuit/control fault rather than a direct measurement of fuel pressure.

What are the most common causes of P0230?

The most common causes of P0230 are: Faulty fuel pump relay, Damaged wiring or connectors in the fuel pump control circuit, Corroded or loose ground/power connection, Failed fuel pump or fuel pump driver module, Blown fuse or fusible link, Open or short in the primary control wiring, Faulty PCM driver output (rare). The specific cause varies by vehicle.

Repair costs for P0230 range from $50 to $2,000, depending on the vehicle and root cause.
