Does a Dodge Avenger have a catalytic converter?

Yes. The Dodge Avenger uses a catalytic converter as part of its exhaust emissions-control system, and most versions have at least one catalytic converter. The exact number and arrangement depend on the model year and engine.

Overview of the Avenger's exhaust and emissions system

The Avenger, produced between 1995 and 2014, follows the standard practice for gasoline-powered cars of its era by incorporating catalytic converters to meet federal and, in some markets, California emissions regulations. The exhaust system typically includes catalytic converters along the route from the engine to the tailpipe, sometimes with additional resonators and a muffler to tune performance and noise. While all Avenger models use catalytic converters, the precise configuration—whether there is one or two converters in series—depends on the engine option and year. If you’re diagnosing a problem or planning replacement, the exact setup should be confirmed for your specific vehicle year and engine via the factory service manual or a parts diagram.

Common catalytic converter configurations

To understand how many catalytic converters a Dodge Avenger might have, it helps to know the two most common setups across its production years. The following outlines the general possibilities you may encounter on different Avengers.

• Single catalytic converter setup: A single unit is located along the exhaust after the manifold. This configuration is found on some engines and model years, typically where emission requirements could be met with one converter.


• Dual catalytic converter setup: Two converters in series, usually a close-coupled converter near the engine and a second converter downstream along the exhaust path. This arrangement is used on some engines and markets to meet stricter emissions standards.

In practice, the exact count and placement vary by year and engine, so the precise configuration for a given Dodge Avenger should be verified from the vehicle’s service information or by inspecting the exhaust system.

Where to look on your specific vehicle

If you want to identify whether your Avenger has one or two catalytic converters, here are practical steps to check the underside and review the engine’s exhaust layout.

• Inspect near the exhaust manifold for a small metal canister—that is typically the close-coupled (near-manifold) catalytic converter.


• Follow the exhaust pipe toward the rear of the car; a second canister farther back indicates a dual-cat setup.


• Consult the vehicle’s VIN-specific service manual or a trusted parts diagram to confirm the exact number and location for your exact year and engine choice.

Knowing the exact configuration helps with parts replacement, diagnostics, and emissions testing. If you’re unsure, consult a qualified mechanic or a Dodge dealer to confirm your model’s exact emissions equipment.

Summary

The Dodge Avenger does have catalytic converters as part of its emissions-control system. The number and arrangement of converters vary by engine and year, with common possibilities including a single converter or two converters in series. For a precise answer on a specific car, check the factory service manual or a reliable parts diagram for that year and engine, or have a professional verify the configuration.

Which vehicles have a catalytic converter?

All modern gasoline and hybrid cars with an internal combustion engine, manufactured from 1975 onwards, have catalytic converters to reduce emissions. Examples include a wide range of vehicles such as the 2024 Toyota RAV4, Honda CR-V, and Chevrolet Equinox, among many others. Older vehicles (pre-1975) and electric vehicles do not have them.
 
Characteristics of cars with catalytic converters

• Engine type: Any car with an internal combustion engine (gasoline or hybrid) will have one. 
• Manufacturing date: Most vehicles made in or after 1975 are required to have them by federal law to control emissions. 
• Examples: A broad range of popular cars, SUVs, and trucks, from brands like Toyota, Honda, Chevrolet, and Ford, are equipped with catalytic converters. 

Cars that do not have catalytic converters

• Electric vehicles (EVs): These vehicles do not have an internal combustion engine, so they do not need a catalytic converter. 
• Pre-1975 vehicles: Cars manufactured before the federal mandate do not have them. 

How much does it cost to replace a catalytic converter on a Dodge Avenger?

between $1,336 and $3,898
The average cost for a Dodge Avenger Catalytic Converter Replacement is between $1,336 and $3,898. Labor costs are estimated between $161 and $237 while parts are priced between $1,175 and $3,661.

How many catalytic converters does a 2008 Dodge Avenger have?

The 2008 Dodge Avenger V6 typically has two catalytic converters—one per exhaust manifold. Inspect the camshaft position sensor and wiring for damage or poor connections. Replace the sensor if faulty.

What is the common problem of Dodge Avenger?

Common Dodge Avenger problems include issues with the automatic transmission, engine stalling, and the engine not starting. Other frequent complaints involve a faulty alternator, electrical problems from a defective TIPM (Totally Integrated Power Module), and the heater not working correctly. Problems can also occur with the independent rear suspension, brakes, and cabin components like the AC.

Engine and starting problems

• Engine stalling and not starting: This can be caused by a failed alternator, faulty starter, a dead battery, or issues with the engine control module (ECM). 
• Engine overheating: A faulty thermostat, radiator fan, or coolant leak can cause the engine to overheat. 
• Engine failure: In some cases, the engine may fail due to a faulty PCM (Powertrain Control Module).
• Misfires: Worn spark plug tube seals can cause misfires, poor fuel economy, and rough running. 

Transmission issues

• Erratic shifting: The automatic transmission may have problems with rough or erratic shifting. 
• Stuck in gear: The transmission can get stuck in a lower gear. 
• Delayed engagement: Delayed shifting, especially between park, drive, and reverse, can occur due to internal component wear or control system issues. 

Electrical and other systems

• Faulty TIPM: A defective TIPM is a known cause of various electrical problems, such as the engine not starting or stalling, dimming lights, and the battery light coming on.
• Alternator failure: The alternator can fail, leading to dimming lights, slow cranking, and a dead battery.
• Electrical issues: Other electrical problems may include the radio and remote keyless entry not working correctly.
• Knocking AC compressor: Owners sometimes report a knocking noise coming from the AC compressor.
• Wet carpet: A clogged evaporator drain can lead to wet carpets inside the car. 

Suspension and brakes 

• Faulty rear suspension: The independent rear suspension, with its multiple links and bushings, is prone to failure. It is recommended to inspect and replace these components if necessary. 
• Squeaking brakes: Squealing brakes are a common complaint reported by owners. 

Interior and body

• Heater failure: The heater core is a weak point and can plug up, resulting in heat only on one side of the car.
• Interior wear: The plastic trim inside the cabin may break, and the edges of seats can show wear.
• Chrome peeling: The chrome on interior door handles can peel, becoming a potential hazard if the edges are sharp.
