What is the purpose of a catalytic converter and how can you check if it is malfunctioning or restricted on Nissan Xterra?

The catalytic converter is an emission control device added to the exhaust system to reduce pollutants from the exhaust gas stream. A monolithic three-way (reduction) catalyst design is used. The catalytic coating on the monolith contains palladium, platinum and rhodium, which lowers the levels of oxides of nitrogen (NOx) as well as hydrocarbons (HC) and carbon monoxide (CO). The test equipment for a catalytic converter is expensive and highly sophisticated. If you suspect that the converter on your vehicle is malfunctioning, take it to a dealer or authorized emissions inspection facility for diagnosis and repair. Whenever the vehicle is raised for servicing of underbody components, check the converter for leaks, corrosion, dents and other damage. Check the welds/flange bolts that attach the front and rear ends of the converter to the exhaust system. If damage is discovered, the converter should be replaced. Although catalytic converters don't break too often, they can become plugged. The easiest way to check for a restricted converter is to use a vacuum gauge to diagnose the effect of a blocked exhaust on intake vacuum. Connect a vacuum gauge to an intake manifold vacuum source. Warm the engine to operating temperature, place the transmission in park and apply the parking brake. Note and record the vacuum reading at idle. Open the throttle until the engine speed is about 2000 rpm. Release the throttle quickly and record the vacuum reading. Perform the test three more times, recording the reading after each test. If the reading after the fourth test is more than one in-Hg lower than the reading recorded at idle, the catalytic converter. muffler or exhaust pipes may be plugged or restricted. Remove the flange bolts and disconnect the exhaust pipe from the catalytic converter. If necessary, remove the necessary exhaust system hangers and move the exhaust pipe rearward. Be sure to support the exhaust system. Remove the flange bolts and separate the catalytic converter from the exhaust pipe or exhaust manifold. Installation is the reverse of removal.

Q: What is the purpose of a catalytic converter and how can you check if it is malfunctioning or restricted on Nissan Xterra?
A:
The catalytic converter is an emission control device added to the exhaust system to reduce pollutants from the exhaust gas stream. A monolithic three-way (reduction) catalyst design is used. The catalytic coating on the monolith contains palladium, platinum and rhodium, which lowers the levels of oxides of nitrogen (NOx) as well as hydrocarbons (HC) and carbon monoxide (CO).

Whenever the vehicle is raised for servicing of underbody components, check the converter for leaks, corrosion, dents and other damage. Check the welds/flange bolts that attach the front and rear ends of the converter to the exhaust system. If damage is discovered, the converter should be replaced. Although catalytic converters don't break too often, they can become plugged. The easiest way to check for a restricted converter is to use a vacuum gauge to diagnose the effect of a blocked exhaust on intake vacuum. Connect a vacuum gauge to an intake manifold vacuum source. Warm the engine to operating temperature, place the transmission in park and apply the parking brake. Note and record the vacuum reading at idle. Open the throttle until the engine speed is about 2000 rpm. Release the throttle quickly and record the vacuum reading. Perform the test three more times, recording the reading after each test. If the reading after the fourth test is more than one in-Hg lower than the reading recorded at idle, the catalytic converter. muffler or exhaust pipes may be plugged or restricted. Remove the flange bolts and disconnect the exhaust pipe from the catalytic converter. If necessary, remove the necessary exhaust system hangers and move the exhaust pipe rearward. Be sure to support the exhaust system. Remove the flange bolts and separate the catalytic converter from the exhaust pipe or exhaust manifold. Installation is the reverse of removal.
