The simple answer is that B-12 Chemtool Total Fuel System Clean-Up (part #2616), our strongest gasoline fuel additive, and a thorough tune-up might help you out. The lengthy response is as follows.
True oxygen sensor cleansers that are secure to run through your engine don’t exist. We do not advise trying to clean O2 sensors, even if some users choose to remove them and use a wire brush or an aerosol cleaner to remove deposits. We believe their function is too important to risk the sensors being harmed and inadvertently (and mistakenly) changing the air-fuel ratio. The threads on the sensor(s) might not be able to withstand repeated removal and installation cycles. They occasionally don’t even make it through an entire cycle!
You cannot directly clean a catalytic converter while it is still attached to the vehicle because anything that may be safely put through the engine will be transformed to CO2, O2, and N2, none of which will perform any cleaning. From that perspective, a “Cleaner for catalytic converters is a gimmick. You do, however, have a few choices.
Considering that catalytic converters “Under specific circumstances, they should be self-cleaning and endure the entire life of the vehicle. If the “If the engine’s internal components are sound and there is just minor catalyst buildup, using a high-performance fuel system cleanser like 2616 and making sure the engine is correctly tuned can be quite beneficial. When the two procedures are combined, it idealizes or “By addressing the combustion byproducts, the catalytic converter is given the opportunity to begin burning/shaking off the deposits and reactivating.
However, nothing can be done to revive them if the catalysts or the supporting structures are physically harmed. This may occur, for example, when unburned fuel exits the combustion chamber after an extended period of time due to old or defective spark plugs, a broken spark plug wire, filthy combustion chambers, etc. When this happens, the catalytic converter may become overheated and eventually begin physically disintegrating. If this has occurred, there is no cleanser in the world that can fix it; instead, the component must be changed.
We offer a dual recommendation as a result of these factors. Fuel lines, fuel injectors, intake valves (in non-direct-injection motors), and combustion chambers can all be cleaned using 2616. Then, having the car serviced will ensure that unburned fuel is not introduced into the exhaust system by paying close attention to the ignition system, including the spark plugs and plug wires. You must drive the car for a long time after running the 2616 and obtaining the tune-up in order to hopefully burn off any deposits that have fouled the catalysts. The best places to drive are on the highway or places with few start-stop cycles. I wish you luck!

Can you clean and reuse an O2 sensor?
An essential component of your car’s pollution control system is an oxygen sensor. Simply explained, an oxygen sensor measures the amount of emissions your automobile emits and transmits that data to the management computer in the engine. There are at least two sensors in your car, and when one of them malfunctions, you need to take action. Can an oxygen sensor be cleaned? Contrary to what you may have heard or read, such sensors should be changed when they malfunction.

What About My Catalytic Converter?
Considering that catalytic converters “Under specific circumstances, they should be self-cleaning and endure the entire life of the vehicle. If the “If the physical integrity of the guts and the catalysts only have some buildup, you can:
Why do oxygen sensors malfunction?
What Leads to the Failure of an Oxygen Sensor? O2 sensors can malfunction as a result of contamination from things like coolant and oil ash. O2 sensors can occasionally stop working for no apparent reason. Other times, contaminants like oil waste and coolant can cause an O2 sensor to malfunction.
O2 sensors’ lifespan is how long?
- Emission levels are very high.
- rotten egg or sulfur odor coming from exhaust
- exhaust black smoke
- Significant Fuel Efficiency Loss
- (and one thing we want to prevent by identifying O2 sensor problems quickly) Suddenly, your catalytic converter fails.
- Your engine stutters, skips, starts to buck, or experiences power spikes.
- When the Check Engine Light Is On
Your catalytic converter is probably at risk if you ignore the warning indications of an O2 sensor problem, and if it breaks down while you’re driving, it could result in additional harm to your car. Depending on how many oxygen sensors your car has, a service that could have cost you a couple hundred dollars could suddenly price you $500 to $2,000 more.
Second, how many oxygen sensors does my vehicle have?
Here is a fast tip to help you figure out how many your automobile has. This will vary from car to car.
Your vehicle will have one catalytic converter for each exhaust pipe (a part that turns harmful gasses into less harmful gasses). You will have two oxygen sensors for every catalytic converter. One catalytic converter and two oxygen sensors are standard in many automobiles, although others may have four or more.
What do Oxygen Sensors do?
These sensors are crucial for fuel delivery, monitoring, timing, MPG, and emissions discharge. They send this data to the engine’s computer for examination after measuring the quantity and quality of oxygen in your exhaust pipe in comparison to ambient oxygen.
And lastly, how long do oxygen sensors typically last?
O2 sensors in older automobiles typically survive 30,000–50,000 miles, or 3–5 years. The sensors used in more recent vehicles have an additional heated element, which increases their likelihood of lasting 100,000 miles, or 7–10 years.
On these sensors, carbon and soot accumulate over time. Grease, oil, or other liquids may be discharged from the exhaust system and adhere to the sensors. The tip of a spark plug is an example of a main element that merely wears out. Your first indication that something may be amiss with your sensors is a lag or Check Engine Light.
Are there ways to prolong the life of my O2 Sensors?
- To avoid using fuel with a lower octane level, check your owners manual for manufacturer advice about fuel octane.
- Avoid buying cheap or inferior gas.
- Maintain your car on a regular basis, paying specific attention to the air filters and spark plugs.
How is an oxygen sensor fixed?
Normally, an O2 sensor that is broken cannot be fixed. Because of the technology and materials used in its housing, it needs to be changed. Some DIY websites may instruct you on how to clean the sensor so you can get a few more miles out of it, but you’re merely postponing what will eventually happen.
What causes carbon to accumulate on oxygen sensors?
Numerous sensors degrade frequently as a result of carbon buildup from a heavy fuel mixture. This could be caused by a number of things, such as a blocked air filter or a fuel injector that is leaking or broken. If antifreeze gets into the combustion chamber, it can seriously damage a sensor.
How is an oxygen sensor tested?
Testing the oxygen sensor’s self-heating is significantly quicker and simpler with clamp-meters. You only need to:
- Ascertain the engine exhaust system’s temperature.
- Set the clamp meter to “DC current/DC amperage” mode and turn it on.
- Place the clamp around one of the power cables for the oxygen sensor heater (but not both). Don’t rest your hand or the tool on the exhaust or engine.
- Start the car’s engine.
- Keep an eye on the reading, which should range from 0.25 to 1.5 A.
The clamp-meter has a number of benefits over a traditional multimeter, including being speedier, more informative, and less invasive because it doesn’t affect the engine’s usual performance.
Can I remove the oxygen sensor with WD40?
It ought to be easy to remove with a 02 sensor tool. The stuck ones can be released with a little tapping and WD40/PB blaster. If not, heat, I concur. It won’t take more than a few minutes to allow the exhaust heat up. After that, focus on releasing it. Remove it entirely after allowing it to cool.
It could be challenging to stick a torch for those resistant people depending on the situation. I’ve used inexpensive o’s from Harbor Freight small and pencil torches. The sensor heats up slowly but effectively over a period of time.
Does changing the oxygen sensor increase fuel efficiency?
Further inspection is always necessary because an illuminated check-engine light may indicate either a simple problem, such as a loose gas cap, or something more significant, such as a problem with the catalytic converter. However, it can be an indication of an issue with your O2 sensor or possibly another component of your exhaust or emissions system. Your check-engine light should be readable by any repair business, and a mechanic or auto parts retailer may do this at no charge.
A rough idle, misfiring spark plugs, a lack of power, stalling, or a considerable rise in fuel consumption are further indications that you need a new oxygen sensor. The EPA claims that changing a defective oxygen sensor can increase fuel efficiency by as much as 40%, so obviously that is one place to look if your car starts to use more petrol. However, same symptoms could also be signs of other issues. A broken O2 sensor may also be to blame if your car fails an emissions test.
Without factoring in labor, the price of a new oxygen sensor can range from less than $100 on some models to $300 or more on others. This is because labor costs depend on where the sensors are positioned in the vehicle. As a result, depending on the type of vehicle you drive, the total cost of oxygen sensor replacement may differ significantly.
A catalytic converter can it self-clean?
A cat that is clogged typically can’t clear itself. However, driving for a prolonged period of time at a specific level of high RPMs is occasionally the only way a cat converter can unclog itself. Since you must maintain it for a very long time, it will be quite difficult to occur without your work.
Finding a highway where you can drive uninterrupted is important if you decide to try it. Just be sure to maintain the engine speed between 2500 and 3000 RPMs for at least 30 minutes.
Efficacy of catalytic converter cleansers
The quick response is no. Because these products contain additives that remove carbon buildup from your engine’s fuel and exhaust systems, using one of them is likely to alleviate symptoms. They won’t, however, totally get rid of them or magically fix your broken catalytic converter.
