P0627 on Honda by model: symptoms, diagnosis and fix
The low-pressure in-tank fuel pump (Denso-supplied) was built with out-of-specification impellers that absorb fuel, swell, and deform over time. A deformed impeller can bind and seize the pump, cutting off fuel delivery. The engine can crank but fail to start, or stall without warning while driving, which is a crash hazard. The defect is part of the massive Honda/Acura fuel-pump recall campaign (originally ~136,000 vehicles, later expanded to ~2.5 million across the brand), with 2018-2020 HR-V 2WD among the affected populations.
Common Symptoms
- Engine cranks but will not start
- Sudden stall while driving
- Whining noise from fuel tank area
- Hard starting when tank is low
- Loss of motive power at speed
How to Fix
This is a safety recall (Honda recall codes including the 2018-2019 HR-V fuel-pump-motor campaign; NHTSA 20V-314 and the expanded 23V-858). Dealers replace the entire fuel pump module/assembly free of charge. Owners should verify VIN status at nhtsa.gov/recalls and schedule the free replacement; out of recall, a Denso/OEM fuel pump assembly runs roughly $400-$800 installed.

Frequently asked questions
What does P0627 mean on a Honda?
P0627 stands for "Fuel Pump "A" Control Circuit/Open." This code means the engine computer detected an open (broken) circuit in the control wiring it uses to command the primary fuel pump, so it cannot reliably switch the pump on. The fuel pump delivers pressurized fuel to the engine, so a control-circuit problem can cause low fuel pressure, hard starting, stalling, no-start, or loss of power. Because it can leave the vehicle stranded, it should be diagnosed promptly. On Honda it is documented across 1 model: HR-V.
What are the most common causes of P0627?
The most common causes of P0627 are: Faulty fuel pump relay or fuel pump driver module, Open, damaged, or corroded wiring in the pump control circuit, Bad electrical connector at the pump, relay, or PCM, Blown fuse in the fuel pump circuit, Failed fuel pump (internal open), Poor ground for the fuel pump circuit, PCM/ECM control driver fault (rare). The specific cause varies by vehicle.
