What is a catalytic converter and how is it checked and replaced on 1997 through 2001 Toyota Avalon?

The catalytic converter is an emission control device in the exhaust system that reduces pollutants. There are two types: oxidation catalyst, which reduces HC and CO levels, and three-way catalyst, which also decreases NOx. Checking the converter requires expensive equipment. During underbody servicing, inspect for leaks, corrosion, and damage. If any damage is found, replace the converter. To diagnose a restricted converter, use a vacuum gauge to assess the impact of a blocked exhaust on the intake vacuum. Connect the gauge to a vacuum source, warm the engine, and note the vacuum reading at idle and after opening the throttle. If the reading is more than one in-Hg lower after the fourth test, there may be a restriction. When replacing the converter, spray the nuts on the exhaust flange studs before removing them, and then proceed to remove the nuts and separate the converter from the exhaust system. The installation process is the reverse of the removal procedure.

How to replace the exhaust manifold and catalytic converter on 2007 through 2015 Toyota Avalon?

Because of a Federally mandated extended warranty that covers emissions related components such as the catalytic converter, check with a dealer service department before replacing the converter at your own expense. The catalytic converter(s) are incorporated into the exhaust manifold(s). Exhaust manifold replacement procedure. Remove the upstream oxygen sensor(s). Remove the exhaust manifold(s). The catalytic converter(s) is an integral part of the exhaust manifold and cannot be replaced separately. If the catalytic converter(s) is bad, the exhaust manifold must be replaced.

Toyota Avalon Catalytic Converter

The Catalytic Converter in Toyota Avalon vehicles is a critical part of the emissions system, which consists of the Carbon Monoxide, Hydrocarbons, and Oxides of Nitrogen and changing them to less hazardous matter such as Water, Carbon Dioxide, and Nitrogen. Usually in the form of a honeycomb structure that is coated with the catalytic components such as platinum, palladium, and rhodium; the converter brings about redox reactions to achieve the above transformation. The year some catalytic converters that incorporated ceramic beads instead of the typical honeycomb construction were used. Despite these difficulties, these converters can poison, steal and be expensive due to the content of the noble metals integrated into them, but new developments have been made regarding the reduction of exhaust restriction and general performance. Toyota Avalon has converters that are both series fit and universal, the series fit do not warrant any changes before installation.
