what does it mean if my Honda Accord Eleventh Generation (2023-present) is showing a B3 code

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure vehicle is parked on a level surface and the engine is cool.
• Disconnect the battery before starting any electrical work.

2. Change Engine Oil

1. Drain the Old Oil:

   • Locate the oil drain plug under the vehicle.
   • Use a socket wrench to remove the drain plug.
   • Allow the oil to fully drain into a container.

2. Replace Oil Filter:

   • Locate the oil filter.
   • Use an oil filter wrench to remove the old oil filter.
   • Apply a small amount of new oil to the rubber gasket of the new oil filter.
   • Install the new oil filter by hand until snug, then tighten slightly more with the wrench.

3. Add New Oil:

   • Replace the drain plug and torque to manufacturer specifications (typically 20-25 ft-lbs).
   • Pour the recommended type and amount of new engine oil (typically 0W-20 for Honda Accord) into the engine via the oil filler cap.
   • Start the engine and let it run for a few minutes to circulate the oil, then check for leaks.

3. Tire Rotation

1. Lift the Vehicle:

   • Use a jack to lift the vehicle and secure it with jack stands.

2. Rotate Tires:

   • Remove the lug nuts using a socket wrench.
   • Swap the front tires with the rear tires and ensure they are properly seated.
   • Reinstall lug nuts and torque them to the manufacturer's specifications (typically 80-100 ft-lbs).

4. Reset Maintenance Light

1. Access the Maintenance Menu:

   • Turn on the ignition without starting the engine.
   • Press the "Home" button on the infotainment system and select "Settings."
   • Navigate to "Vehicle" then "Maintenance."

2. Reset the B3 Code:

   • Select "Reset" for the engine oil and tire rotation maintenance items.
