Two catalytic converters.
In the 2007 CR-V, Honda uses a dual catalytic converter system in the exhaust. A front catalytic converter sits near the engine to start emissions reduction, with a second converter located further back to complete the process before exhaust exits.
The dual-cat configuration in the CR-V
The 2007 CR-V employs two catalytic converters in series to meet emissions standards while supporting engine performance.
What to expect inside the exhaust
The two converters are positioned along the exhaust path: a front pre-cat near the manifold and a rear main-cat downstream. Each converter is monitored by sensors to ensure proper operation.
- Front catalytic converter (pre-cat) near the exhaust manifold begins the emissions-reduction process early in the exhaust stream.
- Rear catalytic converter (main cat) sits further downstream to finish the emissions treatment before the exhaust leaves the vehicle.
In practice, this dual-cat arrangement provides two stages of emissions control and helps the CR-V meet regulatory standards for its year and market.
Location and sensor setup
Placement and sensor arrangement can vary a bit by market or trim, but the general layout remains two catalysts in series with monitoring sensors around each stage.
Maintenance and replacement considerations
If you suspect a catalytic converter issue, consider the symptoms and whether to replace one unit or both. The two-converter system can fail in different ways, and replacing only one may affect emissions monitoring.
Common indicators of a failing catalyst include a check engine light related to catalyst efficiency issues, reduced performance or fuel economy, sulfur smell, or unusual noises from the exhaust. Always consult a qualified mechanic for an accurate diagnosis and proper replacement.
- Check Engine Light or MIL indicating catalytic efficiency issues.
- Decreased acceleration or power loss.
- Lower fuel economy and increased exhaust emissions.
- Unusual sulfur smell from the exhaust.
- Rattling sounds if a converter is physically damaged.
When replacing, mechanics may replace one or both converters depending on damage, emissions requirements, and local regulations. Ensure the work passes any applicable emissions tests.
Summary
The 2007 Honda CR-V uses two catalytic converters—one near the engine and one downstream—forming a dual-cat exhaust system. This configuration is common for this model year and helps meet emissions standards while maintaining performance. If you’re diagnosing issues or planning replacement, consult a qualified technician to confirm the exact setup on your vehicle and ensure proper installation.
How many catalytic converters does a 2007 Honda CRV have?
You don't have two catalytic converters. The front most one is the catalytic converter and behind that, in the middle part of the exhaust is a resonator.
