Engine Light Lexus SC430


Asked by Aug 30, 2019 at 11:14 AM about the 2002 Lexus SC 430

Question type: Maintenance & Repair

I have a 2002 Lexus SC430. Used to be the check engine light was always on. Since replacing the gaskets around the manifold exhaust it only goes on and off intermittently, seemingly randomly. It was suggested that I replace the cat converters or the O2 sensor. Is there a way to acurately diagnose which of those may be bad? or is the engine light on for a different reason? It does not impact performance. thanks.
