Of course, the obvious option for checking the converter for clogging is disassembly and subsequent inspection for the presence of a gap in it. But the fastening of the spare part sometimes gets so stuck that it can only be removed using a bolt cutter or other similar tools. In addition, some manufacturers’ exhaust systems are so complex that replacing them can take a long time to remove.
Today we will talk about the signs of a faulty element without cutting it out. But if you have a spare part that has already been removed on hand, do not throw it away. Using the special Autocatalyst platform, you have the opportunity to profitably sell your old part. You can explore nissan catalytic converter scrap value here. There are many other brands on the site, including Toyota, Rover, Suzuki, Ford, Hyundai and others.
What does it tell you about severe blockage?
Even an inexperienced car owner can easily determine the presence of a malfunction in this unit. If exhaust gasses begin to flow poorly, this will affect the operation of the car as follows:
- The car begins to accelerate much more slowly, which is felt up to a certain point, depending on the degree of contamination or damage to the converter. As a result, it may feel as if there is a significant load in the rear of the car, which causes a slower acceleration.
- A light on the dashboard lights up, indicating problems. When some electronic control units are significantly dirty, an indicator is activated that requires an engine check to warn the driver of a malfunction. An error message may also appear on the on-board computer, indicating problems with the efficiency of the motor.
- The amount of gasoline consumed increases due to a dirty unit. Note that increased consumption indicates a malfunction of the exhaust system only in case of problems with slow acceleration. If a component is severely damaged or clogged, the engine may fail to start or may stop operating within seconds of starting.
If signs of a malfunction of the converter are obvious, then the consequences of operating such a car will be fraught with unpleasant consequences.
Driver options
Experienced drivers advise solving the problem in advance before it causes others. There are several methods:
- Cleaning or flushing the device. This only helps in situations where the blockage is not severe. If the neutralizer is destroyed or melted, or the honeycomb is completely clogged, then this method will not solve the problem.
- Replacing the device with a new one. Original components are expensive, and universal ones are difficult to match to the system configuration.
- Install a flame arrester. The ECU will need to be reflashed or dupes installed.
In case of serious doubts or detection of malfunctions, it is recommended to contact qualified specialists for more detailed diagnostics. Carrying out regular checks will make it possible to prolong the performance of the exhaust gas purification system, but also to prevent more serious breakdowns, ensuring reliable and safe operation of the vehicle.
