The NGK direct-fit oxygen sensor for Toyota Pickup (1989–1991) provides continuous closed-loop air–fuel feedback to the vehicle ECU to help maintain proper mixture, preserve engine performance and reduce emissions. It uses an advanced ceramic sensor element protected by a 3-stage contaminant-resistant plasma jet and deposit-trap overcoat to resist poisoning, with design refinements developed alongside OEM manufacturers for dependable fit and service life.
