Properly Troubleshooting Your Catalytic Converters


The catalytic converter is a very important part of the emissions control system on your vehicle. Occasionally it does fail, though it’s usually good for the lifestyle of a vehicle. The best thing you can do is be alert for signs of head and trouble for a service facility if you suspect the catalytic converter is malfunctioning.

If it changes things, and replace the catalytic converter, if necessary, technicians will put your automobile on an electronic diagnostic machine to locate the original source of the problem, possibly get rid of the oxygen sensor from the exhaust manifold or exhaust pipe ahead of the catalytic converter to discover.

It’s from the law in numerous states to get rid of a catalytic converter and run a vehicle without one.

Listed below are five signs that something may be wrong with your catalytic converter:

Your vehicle’s fuel efficiency suddenly drops.

Your car doesn’t accelerate when you step on the gas pedal.

Your vehicle may refuse to start.

Your automobile fails an emissions test.

The MIL or Check Engine light comes on.

It becomes so clogged that the exhaust gases can’t get through it for the muffler and out of the car. That’s the most typical cause of failure in a catalytic converter in a older car. It can’t come in the front end, so the engine dies because no air is coming straight into form the fuel/air mixture., (If air can’t get out the back of the vehicle)

Every car sold in the United States since 1996 has had an OBD (On-Board Diagnostic) II system that tests the catalytic converter (among many other things). In case the unit allows too much pollution to escape through the tailpipe, it illuminates the MIL and produces a trouble code that can be read by a technician with what’s called a “scan tool.”

If the cylinder head gasket is damaged, allowing oil or coolant to get into the combustion chamber and be burned in the cylinders, the catalytic converter is sensitive to alterations in the contents and temperature in the exhaust gases, so another possible cause of failure is. Also, if your ignition system isn’t operating properly, unburned fuel within the exhaust gases can cause the catalytic converter to wear out or break up. This is another good reason for opting for tune-ups at specified intervals!

Because the catalytic converter can become extremely hot, it’s important not to park your vehicle spanning a bed of dry grass or dry leaves, which may catch fire and destroy not only your vehicle but also the surrounding area!
