Symptoms of a Bad Catalytic Converter in a Ford
When it comes to identifying a bad catalytic converter in a Ford vehicle, there are several symptoms to watch out for. Here are some common signs that may indicate a problem with the catalytic converter:
1. Illuminated Check Engine Light: The first and most common sign of a bad catalytic converter is an illuminated check engine light on the dashboard. When the check engine light comes on, the car’s engine control module (ECM) will also store a diagnostic trouble code, often a P0420 code, in its memory.
2. Sluggish Engine Performance: A bad catalytic converter can lead to sluggish engine performance. You may experience reduced power and acceleration until the issue is fixed.
3. Failed Emissions Test: A catalytic converter’s job is to clean up harmful emissions produced by the engine. If the catalytic converter is not functioning properly, it can cause the vehicle to fail a state emissions test.
4. Reduced Fuel Efficiency: A clogged or failing catalytic converter can restrict the airflow in the exhaust system, leading to reduced fuel efficiency. If you notice a significant decrease in gas mileage, it could be a symptom of a bad catalytic converter.
5. Rotten Egg Smell: A failed catalytic converter can produce a sulfuric, rotten egg-like smell from the exhaust. This odor is caused by unburnt fuel left in the exhaust due to the converter’s inefficiency.
6. Rattling Noises: Another symptom of a bad catalytic converter is rattling noises coming from under the vehicle. If the internal components of the converter become damaged or collapsed, it can cause a rattling sound.
It’s important to note that these symptoms can also be indicative of other issues with the vehicle. If you suspect a problem with your catalytic converter, it is recommended to have it diagnosed and repaired by a qualified mechanic.

How can I test my catalytic converter?
To test for blockage, Access a pressure point before the catalytic converter, install a back pressure gauge and measure the back pressure. Normal reading should be less than 9 kPa @ idle and less than 20 kPa @ 2500 RPM. A high reading indicates the catalytic converter may be damaged or blocked.
How do I know if my catalytic converter is bad or O2 sensor?
To check if it’s a clogged cat versus a bad oxygen sensor (when you don’t have a check engine light), grab a vacuum gauge. Connect the gauge to an intake manifold vacuum line. Start the engine, let it idle, and check the reading on the gauge.
How can I tell if my catalytic converter is bad?
If you’re experiencing a slow engine ability, lowered acceleration, a smell of rotten eggs or sulfur from the exhaust, dark exhaust smoke, or extreme heat coming from under the vehicle, they are symptoms of a clogged Catalytic Converter, and it should get replaced soon.
What happens if you keep driving with a bad catalytic converter?
If it does start, you might face issues like reduced acceleration or power, which isn’t ideal for a long drive. Potential Damage: Continuing to drive with a bad catalytic converter can cause further damage to other parts of your car, like the exhaust system or even the engine.
What are the 3 most leading failures of a catalytic converter?
Most catalytic converter failures fall under one of three categories: Overheated, melted or broken converters.
How much does it cost to replace a catalytic converter in a Ford?
The average cost for a Ford Explorer Catalytic Converter Replacement is between $1,218 and $1,272. Labor costs are estimated between $170 and $214 while parts are priced between $1,048 and $1,058.
What is the life expectancy of a Ford catalytic converter?
around 10 years
A new catalytic converter should last for around 10 years but, as with most other vehicle components, the exact lifespan can differ. Mileage and engine tune can impact on the durability of the item, so it’s worth checking the condition after 50,000 miles.
Will a bad catalytic converter always throw a code?
A bad catalytic converter wouldn’t in itself cause a misfire code, but if the cat. is partially blocked then exhaust gas flow will be impeded and that can cause an engine to misfire if all the old exhaust gas isn’t able to escape the cylinder before the new air/fuel charge is sucked in.
How to test catalytic converter?
To test for blockage, Access a pressure point before the catalytic converter, install a back pressure gauge and measure the back pressure. Normal reading should be less than 9 kPa @ idle and less than 20 kPa @ 2500 RPM. A high reading indicates the catalytic converter may be damaged or blocked.
How do you unclog a catalytic converter?
Soaking: One method to try is submerging and soaking the catalytic converter in a soapy water solution. A dedicated oil or degreaser product will probably work best, though you might also try dish soap. Add your cleaner to a sufficiently large bucket of water where the converter can fit.
