Jeep catalytic converter failure symptoms

The catalytic converter is located on the exhaust pipe system, between your muffler and the exhaust pipe manifold. Depending on the car model, it is installed at different lengths away from the exhaust pipe manifold. My recommendation is always to replace it with an OEM catalyst to reduce future problems with it. Catalysts are susceptible parts and must be first class. A good repair manual will save you both time and money. Check out the best options here.

Hi, I got my engine light on last month and I used OBD II to scan the computer which later came out the code is P, catayltic converter problem too.

However, the light will soon off like running km without touching anything. After, few hundred km running again, it turn it on again and turn it off automatically later as same as above mentioned.

This kind of on and off was appeared more than 4 times already. The catayltic converter was replaced 3 years ago with only about km on it. Could you please to tell any other problem comes out to my case. The exact location of the catalytic converter is going to depend on the model year and engine size of your Jeep Compass.

But, they are not that difficult to locate. The catalytic converter itself is a part of the exhaust system. They almost always have a heat shield around them and an oxygen sensor somewhere before them. It is necessary for the catalytic converter to be before the muffler.

Jeep P Symptoms Check Engine Light is on Lack of power from the engine Decreased fuel economy Rotten egg or sulfur smell Jeep P Causes Faulty oxygen sensor Worn and internally failing catalytic converter Leak in exhaust system Jeep Code P Severity — Moderate While P does not pose a danger to the driver and may not produce any symptoms with issues related to drivability, it can cause severe damage to other components of your Jeep if not addressed in a timely manner.

If other codes are present, they must be addressed first. Examine the exhaust system for damage and leaks.

Pay close attention to the exhaust manifold, gaskets, and exhaust pipes pre-catalytic converter. If any leaks are found, repair the leak, clear the code, and complete several drive cycles to verify that was the fix.

With the Jeep running and at normal operating temperature, use the digital multimeter to check the voltage reading of the downstream O2 sensor.
