How many catalytic converters are in a 2002 Lexus ES300?
There are two catalytic converters in a 2002 Lexus ES300 — one on each bank of its V6 engine.
That means the ES300 uses a dual-bank exhaust configuration. Each bank's exhaust passes through its own catalytic converter as part of the car's emissions control system, with oxygen sensors monitoring performance to satisfy OBD-II requirements.
Configuration and layout
For owners and technicians, the layout is important for diagnosing exhaust, emissions, and sensor issues.
Key details about the setup include:
- Two catalytic converters, one per exhaust bank
- Typically four oxygen sensors in total (two upstream, two downstream) to monitor each converter and the overall exhaust stream
- Converters located close to the engine on the exhaust manifolds
- Part of the vehicle's emissions system designed to meet regulatory standards and support OBD-II diagnostics
When performing maintenance or replacement, mechanics commonly address both converters together to ensure balanced performance and avoid future issues from an aged converter mismatch.
Maintenance considerations
Keep in mind that tampering with or removing catalytic converters is regulated in many regions. Always use OEM or equivalent parts and follow local law when replacing or modifying the exhaust system.
Summary
The 2002 Lexus ES300 uses two catalytic converters, one on each bank of its 3.0-liter V6, with four oxygen sensors contributing to emissions control and OBD-II monitoring.
