However, Mode $06 offers deeper insight. This mode displays the raw test results for non-continuous monitors. The PCM runs specific tests on the catalyst monitor to verify OSC.<\/p>\n\n\n\n<p>Access Mode $06 on your scan tool. Locate the TID (Test ID) and CID (Component ID) for the Catalyst Monitor Bank 1. The data will show a \u201cTest Value,\u201d a \u201cMin Limit,\u201d and a \u201cMax Limit.\u201d Even if the Check Engine Light is off, Mode $06 reveals if the converter is marginally passing. A Test Value perilously close to the failure threshold indicates the <strong>OEM\u89e6\u5a92\u30b3\u30f3\u30d0\u30fc\u30bf\u30fc<\/strong> is degrading. This confirms that a P0420 code is imminent. This step validates the repair before you order expensive parts.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Causes of Converter Degradation<\/h2>\n\n\n\n<p>\u3042 <strong><a href=\"https:\/\/3waycatalyst.com\/ja\/three-way-catalytic-converter-twc\/\">\u4e09\u5143\u89e6\u5a92\u30b3\u30f3\u30d0\u30fc\u30bf<\/a><\/strong> contains no moving parts. It rarely fails on its own. External factors usually destroy it.<\/p>\n\n\n\n<p><strong>1. Thermal Shock and Melting<\/strong><br>Raw fuel entering the exhaust ignites inside the converter. This causes temperatures to exceed 2000\u00b0F (1100\u00b0C). The ceramic substrate melts. This creates a restriction. Backpressure increases. Engine power plummets. Misfires and leaking injectors are the primary causes.<\/p>\n\n\n\n<p><strong>2. Chemical Poisoning<\/strong><br>Certain contaminants coat the precious metals. This renders the washcoat inert.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Silicone:<\/strong> Enters via leaking coolant (head gasket failure) or non-sensor-safe sealants. It coats the sensor and catalyst glass-like.<\/li>\n\n\n\n<li><strong>Phosphorus:<\/strong> Enters via excessive oil consumption. Worn piston rings or valve guides allow oil into the combustion chamber.<\/li>\n\n\n\n<li><strong>\u4e9c\u925b\uff1a<\/strong> Found in certain oil additives. It accumulates on the catalyst surface.<\/li>\n<\/ul>\n\n\n\n<p><strong>3. Mechanical Damage<\/strong><br>Impacts from road debris fracture the ceramic honeycomb. The pieces rattle inside the shell. They block the gas flow. A \u201crattle test\u201d using a rubber mallet confirms this structural failure.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">High-Flow vs. OEM: Understanding Replacement Options<\/h2>\n\n\n\n<p>When replacement becomes necessary, the choice between an <strong>OEM\u89e6\u5a92\u30b3\u30f3\u30d0\u30fc\u30bf\u30fc<\/strong> \u305d\u3057\u3066 <strong>High-Flow Catalytic Converter<\/strong> impacts the repair success.<\/p>\n\n\n\n<p>\u30a2\u30f3 <strong>OEM\u89e6\u5a92\u30b3\u30f3\u30d0\u30fc\u30bf\u30fc<\/strong> contains a high density of cells (typically 400 to 600 Cells Per Square Inch \u2013 CPSI). It also contains a high loading of precious metals. The PCM calibration expects this specific efficiency.<\/p>\n\n\n\n<p>\u3042 <strong>High-Flow Catalytic Converter<\/strong> typically features a lower cell count (200 CPSI). This reduces backpressure and increases horsepower. However, the lower surface area reduces Oxygen Storage Capacity. On a standard street vehicle, a <strong>High-Flow Catalytic Converter<\/strong> often triggers a P0420 code because it cannot store enough oxygen to satisfy the strict factory monitor. You should only use high-flow units on vehicles with modified ECU software (tuning) that accounts for the different efficiency curve. For standard repairs, an OEM or a high-quality \u201cOEM-grade\u201d aftermarket unit is mandatory to keep the light off.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Manufacturer-Specific Diagnostic
