The firing order is 1-6-5-4-3-2.
The 2012 Honda 3.5-liter V6 belongs to Honda’s J-series family and powers several models, including the Accord, Odyssey, Pilot, and Ridgeline. This engine is a 60-degree V6 with double overhead cams and variable valve timing (i-VTEC) in many variants. The firing order—1-6-5-4-3-2—follows the engine’s cylinder arrangement and ignition system design to balance performance and smooth operation across a range of models and trims.
Firing order and cylinder layout
In Honda’s 60-degree V6 layout, three cylinders sit on each bank. The typical left bank is numbered 1-3-5 and the right bank 2-4-6. The ignition sequence 1-6-5-4-3-2 is designed to alternate banks and minimize vibrations while delivering consistent power throughout the engine’s cycle. This arrangement is characteristic of the J-series 3.5 L engines used in 2012-era Honda vehicles.
Practical considerations
When performing maintenance that depends on timing or ignition, such as spark plug replacement or timing-related work, consult the specific vehicle’s service manual for your exact model and trim. While 1-6-5-4-3-2 is commonly cited for the 2012 3.5 L V6, variations can exist between model years and markets, so verify with the official documentation for your car.
