• Pontiac Vibe — selected gasoline-engine applications

A user-maintained vehicle record specifically documents BKR5E1X-11 (5464) being used on a 2007 Toyota Corolla S. Another application source discusses the same plug in Pontiac Vibe applications. These are not sufficient by themselves to confirm every Corolla/Vibe variant.
