Common Issues of a Jeep Wrangler Catalytic Converter
First things first: Just like other catalytic converters out there, a Jeep Wrangler catalytic converter isn't repairable. When you're having problems with it, the only solution would be to get a replacement. With that said, detailed below are the common issues that you may encounter with it.
This is the most common problem that you can encounter with your Jeep Wrangler catalytic converter. Your converter may be clogged because the catalyst materials inside it melted or has been contaminated with silicon. Apart from those, there are numerous possible explanations as to why your catalytic converter is clogged, most of which are related to the fuel system.
There are several ways to confirm catalytic converter clogging. First, you can opt to remove the oxygen sensors in your Jeep's exhaust. You see, clogging deprives your vehicle of oxygen. So if your Jeep's performance noticeably dips without the sensors, then your catalytic converter is most definitely clogged. Another way to confirm clogging is by listening for a whistling sound when your accelerator is applied. The whistling is a result of restricted exhaust flow, thus clogging is definitely present if such a sound can be heard. This sound will only grow louder as you drive at higher speeds. A decrease in fuel economy is another telltale sign of clogging. Clogged catalytic converters use up more fuel than normal-you can expect your fuel gauge to drop faster than usual when this is the case. Lastly, your Jeep's engine will generate backpressure because of clogging. That pretty much means that your vehicle won't be running smoothly.
Once you've confirmed the clogging, you better be ready to fork out some cash for a new Jeep Wrangler catalytic converter.
If contaminants don't cause your Jeep Wrangler catalytic converter to be clogged, then they can at least lower the efficiency of your converter. Aside from contaminants, an improper air-fuel mixture due to a faulty oxygen sensor can also affect your converter's efficiency. This issue can at least be fixed by replacing the problematic sensor.
The diminished efficiency of your Jeep Wrangler catalytic converter can be confirmed via an emissions test.
