Numerous issues could arise from a faulty catalytic converter. If you believe your catalytic converter may be faulty, keep an eye out for these symptoms.
Catalytic converters are notorious for breaking down and are sometimes very expensive to replace, particularly if you're searching for a brand-new one.
To address a problem with your car before it becomes worse, it's critical to recognise the early warning signs of a problem and book your car in with a car services and repair garage.
To avoid replacing a catalytic converter that is in good working order, it is crucial to diagnose a damaged catalyst. What are the most typical symptoms of a damaged catalytic converter, then?
These are the most typical symptoms, though there are many more.
It is advised to check MOT expiry date of your car and, if you are having any problems, have it fixed before your next MOT test to avoid a failure. A defective catalytic converter can also result in an emissions test failure.
If you think your catalytic converter may be malfunctioning, schedule a complete inspection by searching online for a car service near me garage. When the engine is warm and the check engine light is on, the sulphur smell is the most common sign of a failed catalytic converter. In addition, you can observe engine performance difficulties like misfiring, fuel economy issues and sluggish acceleration.
The following are 9 faulty catalytic converter symptoms:
1. Check Engine Light Illuminated - This is one of the most blatant signs that something is wrong with your car, is also one of the best signs that your catalytic converter is failing. It will display a catalytic converter-related issue code when checked with a suitable OBD scanner, which you must be interpretated with the aid of the owner's manual. The P0420 trouble code is the one that is most frequently associated with a faulty catalytic converter. If you check MOT history for your car and establish that a previous MOT test failed due to the engine management light, this could well have been linked to a faulty or clogged catalytic converter. Refer back to any old car repair invoices (if available) to confirm exactly how this issue was fixed.
2. Acceleration Lag - If all other components, such as spark plugs, filters, sensors, etc., are working properly but you notice delays when accelerating or a loss of power when driving up hills, the problem may be with the catalytic converter. Many times, mechanics will confuse a malfunctioning catalytic converter with other parts, such as a bad oxygen sensor or any other sensor.Keep your hand near the end of the exhaust pipe while having someone else press the accelerator pedal to raise the car's RPM to 2000 to check the catalytic converter. You can have a blocked catalytic converter if your exhaust output is insufficient. If you can, compare the flow to a comparable car.
3. Fluctuating Fuel Consumption - One of the signs of a bad catalytic converter is high or low fuel consumption, higher or lower fuel mileage. Even though getting greater fuel mileage can seem like a good bargain, it can harm your engine and lead to even more costly repairs. Your car's engine will be much less efficient and require more effort to produce the same level of power due to inefficient combustion of the fuel when the exhaust is clogged. Therefore, even if lower fuel consumption is occasionally feasible, a defective catalytic converter will typically result in higher fuel use.
4. Smell of Sulphur – A blocked catalytic converter will hinder the airflow of exhaust fumes, causing the air-fuel ratio of the engine to become rich (too much fuel, leading to unburnt fuel). The smell of burnt sulphur or rotten eggs is produced when this extra air-fuel mixture burns, which is a clear sign that your catalytic converter is broken.
5. Discoloured Housing – If you notice that the catalytic converter's housing has taken on a blue or other colour, it may be clogged and producing too much heat. Unburned fuel may enter the catalyst if your engine is not operating as it should, which is another possibility. Due to the heat, this combination then ignites in the converter and melts the inner material, resulting in even additional obstructions. You should not drive your vehicle if you believe that the catalytic converter is faulty since it may be clogged and generate excessive heat inside the engine, which might quickly harm other components.
