How to Test a Bad Catalytic Converter, 2003 Honda Accord Case Study

Join me and learn the steps necessary to condemn a faulty catalytic converter! I covered many different techniques in addressing catalyst efficiency trouble codes, as well as how to do basic testing for exhaust leaks that can potentially cause false converter codes to be set. Some of the techniques I touched on... ~Analyzing downstream oxygen sensor switch rates ~Using tubing to find exhaust leaks ~Using a flammable gas to identify exhaust leaks ~Oxygen storage testing of converters using scan data For more information on the oxygen storage test performed, as well as other catalytic converter testing principals, head on over to the ScannerDanner channel. Here's a link to a video he did covering the subject.    • Diagnosing a catalyst efficiency code (P04...
