The 2014 Honda Odyssey typically has two catalytic converters: a close-coupled unit near the engine and a downstream main converter further back in the exhaust system. This dual-cat setup is common for this era’s V6 Hondas to help meet emissions standards and maintain performance.
What you need to know about the Odyssey's exhaust system
In the 2014 Odyssey, the exhaust system incorporates a dual-catalytic converter arrangement as part of the vehicle's emissions control strategy. Here’s a detailed look at how this setup is organized and why it matters.
Locations of the catalytic converters
Before examining the specific components, note that the two catalytic converters are located along the exhaust path: one close to the engine to heat up quickly, and one farther back to provide additional emissions reduction.
- Close-coupled catalytic converter: mounted near the exhaust manifold, designed to begin reducing pollutants early in the exhaust stream and typically accompanied by upstream oxygen sensors.
- Main (downstream) catalytic converter: located further back in the exhaust system, often along the mid-pipe, providing additional catalytic activity and working in tandem with the first converter.
Understanding their placement helps with maintenance tasks such as sensor replacement, leak inspection, and planning repairs or replacements when needed.
Additional context
While two catalytic converters are standard for the 2014 Odyssey's 3.5L V6, regional variations or model-specific trims can influence exact routing. Always consult the service manual or VIN-specific diagrams for precise locations on your vehicle.
Why this matters
Having two catalytic converters increases the surface area available for catalysis, improves emissions performance, and can affect maintenance costs and scheduling. This configuration is typical for many modern V6 Hondas from that period.
Summary
In short, the 2014 Honda Odyssey generally uses two catalytic converters—one close to the engine and a second downstream—forming a dual-catalyst exhaust system designed to meet emissions standards and support engine efficiency.
For exact details on your specific vehicle, refer to the owner's manual or a Honda service bulletin, as there can be minor variations by region or trim.
How much does it cost to fix P0420 on a Honda?
Most Common Causes of P0420 Code
| Cause | Typical Repair Cost (USD) |
|---|---|
| Failing catalytic converter | $500-$2,500 |
| Faulty oxygen sensor (upstream or downstream) | $150-$400 |
| Exhaust leaks (manifold, pipes) | $100-$600 |
| Engine misfire (spark plugs, coils) | $100-$500 |
How many catalytic converters are on a 2014 Honda Odyssey?
three converters
The catalytic converters on your 2012-2017 Honda Odyssey are a critical part of its exhaust system. Your Odyssey's J35 V6 engine has three converters: one for the front bank of cylinders (Bank 2), one for the rear bank (Bank 1), and a third one downstream.
How much does it cost to replace a catalytic converter on a 2014 Honda Odyssey?
between $1,342 and $1,771
The average cost for a 2014 Honda Odyssey Catalytic Converter Replacement is between $1,342 and $1,771. Labor costs are estimated between $73 and $107 while parts are priced between $1,269 and $1,663. This range does not include taxes and fees, and does not factor in your unique location.
Can you unclog a catalytic converter instead of replacing it?
Unfortunately, cleaning your catalytic converter does not guarantee it will work effectively afterward. If your converter is defective, cleaning it will not make an impact, and any symptoms present before the cleaning process will return. In the end, if nothing works, a replacement is the way to go.
