1. Understanding Catalytic Converters in Your 2007 Toyota Camry
Yes, a 2007 Toyota Camry is designed with two catalytic converters to effectively reduce harmful emissions. These converters play a crucial role in converting pollutants into less harmful substances, ensuring your Camry meets environmental standards.
1.1. What is a Catalytic Converter?
A catalytic converter is an exhaust emission control device that reduces toxic gases and pollutants in exhaust gas from an internal combustion engine into less-toxic pollutants. The catalytic converter relies on chemical reactions to reduce emissions of hydrocarbons (HC), carbon monoxide (CO), and nitrogen oxides (NOx).
1.2. Why Does My 2007 Camry Need Two Catalytic Converters?
The use of two catalytic converters in a 2007 Toyota Camry enhances the efficiency of emission control. The first converter, often a three-way catalyst, focuses on reducing NOx, HC, and CO simultaneously. The second converter further cleans the exhaust, ensuring a higher level of pollution control, and meeting stringent environmental regulations.
1.3. Where Are the Catalytic Converters Located in a 2007 Camry?
In a 2007 Toyota Camry, the catalytic converters are strategically positioned within the exhaust system. Typically, the first catalytic converter is located closer to the engine, directly after the exhaust manifold. The second converter is positioned downstream, further along the exhaust pipe. This placement allows both converters to efficiently treat exhaust gases.
2. Signs Your Catalytic Converter May Need Attention
Identifying potential issues with your catalytic converter early can prevent more extensive damage. Here are some symptoms to watch for in your 2007 Toyota Camry:
- Reduced Engine Performance: A clogged or failing converter restricts exhaust flow, diminishing engine power and acceleration.
- Decreased Fuel Efficiency: Inefficient converters can cause the engine to work harder, leading to lower miles per gallon.
- Check Engine Light: This is a common indicator of various issues, including catalytic converter problems, as detected by the car’s computer system.
- Rattling Noises: Internal damage to the converter can cause rattling sounds, especially during startup or acceleration.
- Failed Emissions Test: A faulty converter often results in failing an emissions test due to high levels of pollutants.
- Overheating: A failing converter can overheat, potentially causing damage to nearby components.
- Sulfur Smell: A rotten egg smell indicates that the catalytic converter is not properly converting hydrogen sulfide into sulfur dioxide.
2.1. The Role of Oxygen Sensors
Oxygen sensors play a vital role in the proper functioning of the catalytic converter. They monitor the amount of oxygen in the exhaust gases, providing feedback to the engine control unit (ECU). This feedback helps the ECU adjust the air-fuel mixture to ensure optimal catalytic converter performance.
There should be two oxygen sensors, one above and one below the first catalyst. Usually the top sensor fails first, but I replace them in pairs.
2.2. Diagnosing Catalytic Converter Issues
A professional mechanic can diagnose catalytic converter issues through several methods:
- Visual Inspection: Checking for physical damage, rust, or leaks.
- OBD-II Scanner: Reading diagnostic trouble codes (DTCs) to identify specific issues.
- Backpressure Test: Measuring the exhaust backpressure to determine if the converter is clogged.
- Temperature Test: Using an infrared thermometer to measure the temperature difference between the inlet and outlet of the converter.
3. Replacing Your Catalytic Converter
If your catalytic converter is failing, replacement is often the best course of action. Here’s what you need to know:
3.1. When is Replacement Necessary?
Replacement is usually necessary when the catalytic converter is severely damaged, clogged, or has failed an emissions test. Ignoring these issues can lead to further engine damage and increased pollution.
3.2. Choosing the Right Replacement
When selecting a replacement catalytic converter, consider the following:
- OEM vs. Aftermarket: Original Equipment Manufacturer (OEM) converters are designed specifically for your vehicle, ensuring optimal performance and fit. Aftermarket converters are generally more affordable but may not offer the same level of performance.
- Compliance: Ensure the replacement converter meets EPA or CARB (California Air Resources Board) standards, depending on your location.
- Warranty: Look for converters with a good warranty to protect against premature failure.
If yours are the original sensors with almost 200k miles on them, I would not spend money to pay someone to tell me that they are getting old (which they are by now), and then pay him over $100 each for new sensors. I would buy a new ones on line and put them in myself. It will cost you about $80 each for sensors that fit or $40 each for generic fit that you have to attach your old plug to.
You have literally nothing to loose by trying new oxygen sensors, because if you do need a new catalyst, you will replace the sensors as well.
3.3. The Replacement Process
Replacing a catalytic converter involves several steps:
- Preparation: Gather the necessary tools, including wrenches, sockets, and safety glasses.
- Removal: Disconnect the oxygen sensors and remove the old converter from the exhaust system.
- Installation: Install the new converter, ensuring proper alignment and secure connections.
- Reconnection: Reconnect the oxygen sensors and any other components that were removed.
- Testing: Start the engine and check for leaks or unusual noises.
3.4. Professional Installation vs. DIY
While it is possible to replace a catalytic converter yourself, professional installation is often recommended. A professional mechanic can ensure the job is done correctly, preventing future issues.

I am not certain, but I presume that the two catalysts are completely different. One promotes reduction (removal of oxygen) of NOx, and the other promotes oxydation (addition of oxygen) to CO and VOC.
You can’t relocate the downstream the oxygen sensor, and even if you could, doing so would cost more and be more work than replacing the sensor.
People often scold me for “throwing parts at the problem” but if I have to remove a part to examine or test it, and it is a part that is subject to failure and it has over 100k miles on it, there is no point in testing it because I am not putting that old part back on my car.
