The NGK OE‑type 4‑wire air/fuel sensor for 2012–2019 Toyota Prius C models is a direct replacement that restores accurate air–fuel ratio sensing for the hybrid’s engine control system. Matching the factory four‑wire configuration and fit, it supplies the feedback necessary for fuel‑trim and emissions monitoring and installs in the original location as an OE‑style service part.
