Emission control device is subjected to constant stress and sooner or later it will fail. In Ford Expedition cars, this can happen for various reasons: because of bad fuel, because of mechanical damage, simply because of natural wear, which comes to all devices after 100-200 kilometers of mileage (depending on the operating conditions).
If the part is no longer working at all, the only option is to sell it on the AutoCatalystMarket platform page https://autocatalystmarket.com/us/en/models/ford-expedition and buy a new one. And further we will consider the signs, by which you can suspect problems with this node.
Main characteristic signs of exhaust purifier failure
Let’s consider a few of the most common phenomena that are associated with the breakdown of this part of the car. If you notice any of these at yourself – be sure to contact the car service as soon as possible.
- First – the indicator on the dashboard lights up.
We are talking about the very icon “Check Engine”, which indicates many problems, not just the “diseases” of the device. However, it is still worth mentioning it, because in a complex with other problems, it accurately indicates a specific problem.
- Power problems.
You may notice that when you press the gas pedal, the car doesn’t respond as quickly as it used to.The engine becomes generally not as productive as before, which is often due to a malfunctioning emission control device. This is because it is unable to fully process the gases that are released when the fuel is burned. This affects both the engine and other parts of the car.
- Unsteadiness of the car during idling.
When the car is started but standing still, the engine runs at minimum rpm just to avoid stalling. If the device that cleans the exhaust is malfunctioning, the idling can be affected. When the car is standing still, you may experience twitching, uneven engine performance, or even stalling.
- Increased fuel costs.
Motorists always know how many kilometers they have enough for one refueling. If the consumption becomes higher, but the motorist does not drive more, it is a reason to think about it. Perhaps there are problems with the exhaust treatment system. This is due to the fact that the fuel is not burned as efficiently as when the node is working properly.
- Strange sounds or odors.
It is very easy to notice if when driving the car has new sounds that do not resemble normal sounds. When there are problems with the catalytic converter, it can be a tapping sound that can be heard from the rear of the car. This happens if something has broken inside the design of this device.
Odors also appear quite quickly, if there is a malfunction with this node. In the cabin, you can hear a characteristic smell of gases or sulfur. This will be evidence that you urgently need to go to a car service and find out the cause of unpleasant changes.
