Honda Odyssey maintenance schedule
The Honda Odyssey maintenance schedule follows the Maintenance Minder: the van shows a code such as A1 or B124 when a service is due. The item to plan for is the V6 timing belt, which comes up under code 4 and, per the 2010 manual, every 60,000 miles if you regularly drive in extreme heat or cold. Change the oil when the Minder asks or once a year, and the brake fluid every 3 years.

How the Minder schedules an Odyssey
The display counts oil life down and shows a code at 15%. The letter is the oil job: A for new oil, B for new oil and filter plus an inspection of brakes, suspension, and fluids. Each number adds a job: 1 tire rotation, 2 air filters and drive belt, 3 transmission fluid, 4 spark plugs and timing belt, 5 coolant. The Odyssey is front-wheel drive, so code 6 never appears. All codes: Honda Maintenance Minder codes. Honda’s system across models: Honda maintenance schedule.

The timing belt on the Odyssey V6
Every Odyssey since 2008 has a 3.5-liter V6 with a timing belt. The Minder includes it in code 4, alongside spark plugs, a water pump inspection, and valve clearance. Honda’s 2010 manual adds a fixed rule for the 3rd-generation van: replace the belt every 60,000 miles if you often drive where it is over 110°F or under −20°F, because the Minder can’t sense outside temperature. The later manuals we checked put the belt under code 4; read the maintenance section of yours for any hard-use rule.
A belt job is a large bill. Get a written quote that lists the belt, water pump, and tensioner, and keep the receipt for resale. More: timing belt replacement.
Codes you will see on an Odyssey
- A1 and B1: oil and tire rotation. A heavy van wears tires faster when rotations are skipped.
- B12: engine and cabin air filters. The cabin filter matters more in a van full of kids and pets.
- B13: automatic transmission fluid. The 5-, 6-, 9-, and 10-speed automatics each use the Honda fluid named in the manual.
- B14: spark plugs, valves, and the timing belt.
- B123: a stacked visit for a van that has racked up miles.
Normal or severe?
The Minder already shortens oil life for short trips, stop-and-go traffic, and cold starts, the way most minivans are driven. It can’t see dust (replace the engine air filter every 15,000 miles on dusty roads), extreme outside temperatures (the timing belt rule above), or the age of the brake fluid (every 3 years). See normal vs severe maintenance.
