A worn oxygen sensor can show up as a check engine light, a rough idle or poorer fuel economy, though a problem elsewhere in the engine could be behind any of them. With the engine off and cool, look over the wiring and connector for damage or burn marks; if this sensor is the cause, it replaces the old one.

Fits

The same sensor fits the 1990-1993 Toyota Celica 4-cylinder 1.6L and the 1989-1992 Geo Prizm 4-cylinder 1.6L. This listing is one upstream sensor, and the 1.6L four-cylinder takes a single one.
