Understanding your Toyota Camry’s fuse box is crucial for troubleshooting electrical issues. For 2010 Camry owners, locating the OBD2 fuse is particularly important when diagnosing engine or system problems using an OBD2 scanner. This guide will help you pinpoint the OBD2 fuse location in your 2010 Toyota Camry, ensuring you can effectively use your diagnostic tools.
Your 2010 Toyota Camry has two main fuse box locations:
- Engine Compartment: This fuse box, often referred to as the engine room fuse box, is located under the hood, usually near the battery or engine. It houses fuses and relays related to critical engine and vehicle functions.

Finding the OBD2 Fuse
The OBD2 (On-Board Diagnostics II) system is essential for vehicle diagnostics and emissions testing. The fuse for the OBD2 port in your 2010 Toyota Camry is located in the fuse box under the instrument panel, inside the vehicle.
According to the fuse diagram and list, the OBD fuse is located at position 5 in the interior fuse box. It is a 7.5A MINI fuse.
To access the interior fuse box and check the OBD fuse:
- Locate the Fuse Box: Get into the driver’s side of your Camry and look under the dashboard, above the pedals. You should see a cover for the fuse box.
- Open the Fuse Box Cover: There’s usually a latch or clip to release the cover. Open it to expose the fuses.
- Identify the OBD Fuse: Refer to the diagram printed on the inside of the fuse box cover, or use the tables below to locate fuse number 5, labeled OBD.
- Check the Fuse: Visually inspect the fuse. If the wire inside the fuse is broken or melted, the fuse is blown and needs to be replaced. You can also use a fuse tester for confirmation.

Why Check the OBD2 Fuse?
If you are trying to use an OBD2 scanner and it’s not powering up or connecting to your 2010 Camry’s computer, the first thing to check is the OBD2 fuse. A blown OBD2 fuse will cut power to the diagnostic port, preventing your scanner from working. This can happen due to a short circuit in the scanner, the OBD2 port itself, or related wiring.
By knowing the location of the 2010 Camry OBD2 fuse, you can quickly troubleshoot diagnostic issues and ensure you can effectively read your vehicle’s data for maintenance and repairs. Remember to replace a blown fuse with one of the same amperage rating to avoid further electrical problems.
