Where is the catalytic converter on a Honda Ridgeline?
The catalytic converter on a Honda Ridgeline is part of the exhaust system and sits under the vehicle along the exhaust path, typically on the passenger side, between the engine and the rear section. The exact position varies by generation and trim; some models use one converter while others may use two in series.
Overview by generation
First-generation Ridgeline (2006–2014)
Use the quick-find guide below to locate the catalytic converter on Gen 1 Ridgelines.
- Where to look: under the vehicle along the exhaust path on the passenger side, roughly between the front wheels and the midsection of the truck.
- Appearance: a large metal canister on the exhaust pipe, often shielded by a heat shield.
- Sensors: you will typically find oxygen sensors near the converter (one upstream, one downstream) to monitor emissions.
- Configuration: some models may have two catalytic converters in the exhaust run (front and rear) depending on the exact trim and emissions package.
In Gen 1 Ridgelines, expect the catalytic converter to sit along the exhaust path beneath the vehicle, with the potential for more than one converter in certain configurations.
Second-generation Ridgeline (2017–2023)
Use the quick-find guide below to locate the catalytic converter on Gen 2 Ridgelines.
- Where to look: along the underbody exhaust route, typically toward the center of the chassis and often on the passenger side.
- Appearance: one or more metal canisters in the exhaust line, usually protected by heat shields.
- Sensors: expect an upstream and downstream oxygen sensor associated with the cat location.
- Configuration: many Gen 2 setups use a single catalytic converter, but some configurations may include a second converter further back in the exhaust path.
For Gen 2 Ridgelines, the catalytic converter remains part of the mid-to-rear exhaust section under the vehicle, with similar sensing features to help monitor emissions.
Third-generation Ridgeline (2024–present)
Use the quick-find guide below to locate the catalytic converter on the current generation Ridgelines.
- Where to look: along the underbody exhaust path, commonly near the center of the vehicle or slightly toward the passenger side, depending on the specific chassis layout.
- Appearance: one or more metal canisters on the exhaust line, often with heat shielding in place.
- Sensors: an upstream and downstream oxygen sensor are typically installed around the converter(s).
- Configuration: the latest generation continues to use catalytic converters as part of the exhaust after-treatment system, with variations by market and trim.
In the current generation, expect the catalytic converter to be mounted along the exhaust route under the vehicle, with variations possible by model year and region.
What to know when inspecting or working on it
When locating or servicing the catalytic converter, safety is paramount. Use proper jack stands and lighting, check for heat shields, and identify oxygen sensors near the converter to confirm you’ve found the correct component. If you’re replacing or modifying the exhaust, consult the official service manual or a qualified mechanic for model-year-specific guidance.
Summary
Across Honda Ridgeline generations, the catalytic converter is located along the underbody exhaust path, most commonly on the passenger side and roughly between the engine and the rear of the vehicle. Some models use one converter, while others may include two in series depending on year and emissions configuration. Always verify with the owner’s manual or service guide for your exact model year.
