2001 Toyota Sienna 6 cyl Two Wheel Drive Automatic 148000 miles
Technician says need to replace ECM bases on Toyota Tech Bulletin. It is not under warranty anymore. First, is the Cat Converter really bad and needs to be fixed? Second, why would Toyota put a defective ECM and not replace it?
If it is just a false alarm because of defective ECM, can I just ignore it?
have the same problem?
