Signs of a Faulty Jeep Liberty Catalytic Converter
A catalytic converter is an important component of your Jeep Liberty's exhaust system. By changing noxious gases into usable compounds, it helps reduce the harmful effects of emissions and helps improve the performance of your vehicle. However, the catalytic converter is a bit pricey compared to other car parts; it also needs to be checked from time to time to make sure that it works and that your car will pass the smog test. To save yourself from unexpected high costs and further trouble, you must diagnose a converter problem before it worsens. Read on for some of the common signs of a faulty Jeep Liberty catalytic converter:
Heed a warning when you see it. If the "check engine" light of your Jeep Liberty turns on, make the necessary diagnosis. Though the CEL will come on for a number of reasons, it is best to check the primary parts of the vehicle right away-that includes the precious catalytic converter. There are readers available in most car parts retailers that can help you read the error code to easily identify the root cause of the LED warning.
Rattling, as in most cases, suggests a problem. If you hear consistent noise in the converter area, check for internal trouble. You can do this by hitting the converter with a rubber mallet, but make sure first that the converter has already cooled. Loose parts will expectedly make some noise. In this case, consider immediate replacement.
Poor engine performance
Have you experienced adding pressure on the car's throttle, only to be answered with a refusal to go faster? If you answer yes and you observe no increase in the RPMs of your car, your Jeep Liberty catalytic converter might be plugged. In the long run, this could result in poor fuel mileage and optimum performance reduction. You can use a pressure gauge to check if you really have a plugged converter. Install it in place of the front oxygen and test the converter for excessive exhaust pressure. If it is positive of extra compression, try loosening the exhaust connections and then restart the engine. A noticeable change after that also indicates the need for immediate replacement.
Other troubleshooting notes
Even if there are reliable kits and repair manuals available for DIYers, it is still best to consult automotive professionals once symptoms of a failing catalytic converter arise. Most converters are also covered by a warranty, so you can also seek assistance from retailers when problems occur.
