P0627 on Honda
Fuel Pump "A" Control Circuit/Open
P0627 on Honda vehicles indicates fuel pump "a" control circuit/open. Au7o has documented this code across 1 Honda model — most commonly on HR-V. 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.
Common Causes of P0627
- •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)
P0627 on Honda by Model
Honda HR-V(1 issue)
- Fuel Pump Impeller Swelling Causing Engine Stall (Recall C2P / 20V-314 / 23V-858)2018-2020
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.

What does P0627 mean on 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 specifically, this code is documented across 1 model.
