Consumer Description
This is in regards to toyota CSP 24TE04 and the Engine Bypass System. This was also included in a class action lawsuit that got dropped. Engine Bypass System is faulty and shows check engine requiring replacing of Bypass Valve and or wiring. According to 24TE04 it has been affecting over 2 million cars, but not all are being fairly covered. They need to include all models with this system that were produced during this time. Thank you
