Catalytic clogged converter

You may need to fix other engine problems in order to solve your catalytic converter problem. A lazy oxygen sensor might falsely indicate a catalytic converter problem, yet not set a DTC for itself.

A technician can determine if the sensor is responding as it should. Other engine problems, such as fuel trim running too rich or too lean, oil or coolant burning, or engine misfire problems could all lead to catalytic converter contamination or premature failure.

Depending on the extent of the damage already done, fixing engine problems might save the catalytic converter from a meltdown. Exhaust leaks are common and can skew oxygen sensor readings without setting other DTCs. Worn exhaust gaskets and corroded flex pipes are two common issues that are significantly less expensive and more effective than replacing a catalytic converter.

Removing and cleaning the catalytic converter is another potential fix. After removing the catalytic converter, use a pressure washer to blast out any contaminants from the matrix. Be sure to flush the unit from both ends. Another way to clean the catalytic converter is to soak it overnight in a combination of hot water and degreaser or laundry detergent. This process takes longer but is necessary to dissolve the deposits clogging up your catalytic converter.

After washing or soaking, be sure to dry the catalytic converter completely before reinstalling. This happens if your catalytic converter is so clogged that pieces of debris break off and get stuck in the muffler.

As for the simple answer, if the O2 exhaust sensor voltage fluctuates a lot, your catalytic converter is clogged.

Although do keep in mind that it is also possible for the muffler to be clogged if your catalytic converter got so bad that parts of the debris flew out into the muffler. To check what voltage your O2 sensor is, and determine if it is clogged or not, do the following procedure:.

Engine problems could be in the form of poor acceleration, difficulty starting the engine, rpm instability, capped speed, etc. Often the temperature gauge will run a little bit hotter because the exhaust gasses are staying in the engine for too long, making it run hotter. Or the car will only go up to a certain speed and no further.

Another way to tell if your catalytic converter is clogged is by the use of the infrared thermometer. Since clogged catalytic converters tend to run hotter, you can check the temperature of the exhaust pipe before the catalytic converter and after.

However, when this does happen, it means that your catalytic converter might get flooded with unburnt gasoline which can clog the converter or even start an engine fire.

This can be extremely dangerous, so be sure to take your car in for an inspection. Another fairly common symptom of a clogged catalytic converter is a significant decrease in fuel economy.

If your cats are clogged, your engine will burn more fuel because there is a reduced amount of oxygen in the engine. As far as clogged catalytic converter symptoms go, this one is indeed easy to spot. However, be sure to pinpoint the issue before you start repairing the converter. If your catalytic converter becomes extremely clogged, your performance is also bound to suffer, more specifically, your acceleration.

Whenever there is an excessive carbon buildup inside your catalytic converters or there is just too much unburnt fuel, your cats will become clogged. As such, your engine is not going to be able to breathe properly which will result in subpar acceleration. Many countries around the world are imposing strict rules on obligatory emissions testing, and in the US you are obligated to test your car for emissions every 1 to 2 years.

Most newer cars are usually tested through the OBD port, but older models are usually tested with special hoses connected to the exhaust. A clogged catalytic converter is one of the most common reasons why people fail such testings. This symptom usually means that your cats are unable to convert sulfide into odorless sulfur dioxide, which indicates either a broken or a clogged cat.

Be sure not to leave your car running in a closed garage as sulfur is extremely toxic. If the pressure inside the catalytic converter grows to an uncontrollable level, it clogs itself completely.

This means that the pressure inside the engine is going to grow dramatically and is likely going to completely lock the engine thus making it unable to start up. Engines such as these have usually been under a lot of stress before they stopped working entirely.

Whenever your catalytic converter starts clogging up, it usually means that the gasses leaving the exhaust will be significantly darker in color. This is because higher pressure starts building up in the engine until the pressure is finally high enough for those gasses to be pushed out. To make sure that your catalytic converter remains unlogged, you can regularly drive at a high rev for half an hour at least once a month.

Unplugging a catalytic converter is easy, but there are regulations in some areas against operating a street vehicle with converters that have been unplugged. When a catalytic converter gets plugged, the only way to unplug it is by removing the mesh screens that are blocked with deposit material.

When a catalytic converter starts to fail, such as when clogs occur, deterioration can happen quite quickly. You can go for a catalytic converter cleaner at any automotive supply store and can buy it online according to the make and model of your car.

You can take advantage of a useful fuel or fuel additive to unclog a catalytic converter. Your email address will not be published. Save my name, email, and website in this browser for the next time I comment.
