Troubleshooting common O2 sensor errors

O2 sensor problems and catalytic converter issues can trigger similar warning signs — but the fixes are very different. In this Ask the Team video, we asked Cristian: “What’s a sign your O2 sensor is failing vs. a catalytic converter issue?” He explains how to tell the difference by looking at symptoms, fault codes, and how the engine responds.
