What Does the B125 Honda Service Mean?

Your Honda’s Maintenance Minder system monitors oil life, fluid levels (like engine coolant and transmission fluid), and engine conditions to generate a service code like B125. It monitors important safety features of your Honda vehicle (be it a Honda Civic, Accord, or any other model). 

The B125 code in any vehicle by the Honda Motor Company means:

 

  • B = Replace the engine oil and filter. Clean the rear brakes, adjust the parking brake, and perform an inspection of brake hoses, exhaust system, fluids, fuel lines, and other connections.
  • 1 = Rotate tires, perform tire pressure inspection, and check for damage. 
  • 2 = Replace the air filter or air cleaner element (used to catch dust) and inspect the drive belt.
  • 5 = Replace the coolant.

The triggering of a B125 code varies based on driving habits, oil type, and overall vehicle condition. It’s best to get it diagnosed and fixed by a reliable mechanic or any Honda dealership to have confidence in your vehicle’s safety.

How Do You Fix a B125 Honda Service Code?

1. Get an Oil Change

Your Honda’s motor oil reduces friction between parts, prevents wear, and dissipates heat from fuel combustion. As it circulates around the engine parts, it collects debris and dirt, reducing the engine oil life. 

The oil filter catches contaminants, preventing them from blocking the system. However, dirty engine oil can clog the filter over time, and you may even notice a lit oil warning light. You’ll need to replace the oil filter and get an oil change.

2. Rotate Tires

Since the front tires bear more force than the rear tires, their treads (the deep groove and line on your tires) wear out faster. 

Swapping the order of your Honda vehicle tires balances the wear and prolongs tread life.

3. Replace the Air Filter

Aside from breathing in clean air inside the cabin, your car needs filtered air to burn fuel properly.

Your Honda Motor Company vehicle has two air cleaner elements: the cabin air filter and the engine air filter. Both parts work by filtering pollutants, allergens, dust, and more from the air that enters the vehicle. 

4. Flush Out the Old Coolant

Engine coolant fluid absorbs engine heat, cools in the radiator, and cycles back. A coolant or radiator flush is a routine maintenance service. It involves draining the old engine coolant and replacing it with fresh fluid.

How Much Does Honda B125 Service Cost?

The B125 service typically costs $400 to $550 in a service center. However, this rate may vary depending on your Honda model. For example, the average annual repair cost of a Honda Accord is $400 per year, while that of a Honda Civic is $368.

Here’s an overview in detail of how much you may need to pay at the Honda Dealership or your local mechanic for specific parts and any additional service:

  • B Service: The ‘B service’ costs between $50 and $100, mostly due to the purchase of the oil filter and fluids (like transmission fluid and engine coolant). However, using synthetic oil and having rear brakes or parking brake problems can increase the cost
  • 1 Service: The ‘1 service’, or tire rotation and tire pressure inspection, can cost about $30 to $45.
  • 2 Service: The ‘2 service’ includes engine and air filter replacements and a drive belt (not to be confused with the timing belt) inspection. As you’ll have to purchase a few parts for this, it can typically cost $100 to $150.
  • 5 Service: The ‘5 service’ can range from $150 to $250, depending on your vehicle’s coolant capacity.

When Should You Get a B125 Service?

You should typically get a B125 express service whenever the Maintenance Minder tells you to. It’ll allow you to drive with more confidence without worrying about your car’s safety. But here’s a bit more detail on how often your Honda model needs an additional service:

  • Oil flush and oil filter change: Every 7,500 to 10,000 mile interval
  • Tire rotation: Every 5,000 to 7,500 mile interval
  • Air filter (cabin air filter and engine air filter) replacement: Every three years or 15,000 to 30,000 miles
  • Coolant flush: Every two years or 30,000-miles

Note: Your driving habits and the oil you use can affect these ranges. Refer to your owner’s manual or contact your mechanic for more detailed information.
