Power Loss And Acceleration Issues
Temperature and pressure tests help check if the catalytic converter is clogged. These tests measure how well exhaust gases flow through the converter. A clogged converter causes unusual temperature and pressure readings. Mechanics use these tests to find blockages inside the catalytic converter.
Temperature Test
The temperature test compares the heat before and after the catalytic converter. A healthy converter gets hotter at the outlet than the inlet. This happens because it burns harmful gases inside. If the outlet temperature is lower or almost the same as the inlet, the converter might be clogged. A clogged converter stops gases from passing freely, reducing heat buildup.
Pressure Test
The pressure test measures exhaust pressure before and after the catalytic converter. A clogged converter causes higher pressure before it and lower pressure after it. Mechanics use a pressure gauge to check this difference. Large pressure differences show a blockage that slows exhaust flow. This test helps confirm if the catalytic converter is the problem.
