2015–2024 Honda Accord Fuse Box Diagram
Engine compartment fuse box, Interior main fuse box, Interior sub fuse box (auto idle stop models): every fuse, its amp rating, and what it protects.
Quick answer
The 2018 to 2022 Accord has an engine compartment fuse box next to the battery, an interior main fuse box under the dashboard, and, on cars with auto idle stop, a small interior sub fuse box. Honda prints the slot layout on the box cover and the side-panel label rather than in the manual, so this page lists every fuse number, rating and circuit from the manual; match the number to the label in your car.
Generation: 10th generation (2018–2022) · Body styles: sedan
Engine compartment fuse box
Location: Near the battery; push the tabs to open the cover. Positions 2 to 5 are multi-fuse blocks.
The manufacturer prints this box’s layout on the fuse box cover label, not in the manual, so positions are not drawn here. Use the fuse number from the table and match it to the number on the cover.

Replace a fuse only with the same rating. A blown fuse that blows again is telling you about a short or an overloaded circuit, not about the fuse.

Frequently asked questions
- Where is the fuse box on a 2018 to 2022 Accord?
- Two or three places: the engine compartment box next to the battery, the interior main fuse box under the dashboard on the driver side (label on the side panel), and on cars with auto idle stop a small sub fuse box under the dash as well.
- Which fuse is the fuel pump on the Accord?
- Engine compartment fuse box, number 40, a 20 A fuse labeled IG1 FUEL PUMP. Check it before the relay or the pump if the engine cranks and the pump is silent.
- Why are so many interior positions empty?
- Honda uses one fuse box design across trims and markets, so positions for equipment your car does not have are left empty. An empty socket in the chart is normal, not a missing fuse.
