AE92 NTK Downstream Oxygen Sensor | 4A-GE California Emissions (1989-91 Corolla)

NTK Downstream Oxygen Sensor

For 1989–1991 Toyota Corolla AE92 coupe equipped with the 4A-GE and California emissions.

Overview

This NTK oxygen sensor replaces the No. 2 downstream sensor on 1989–1991 U.S.-market Toyota Corolla AE92 GT-S coupes with the 4A-GE and California emissions. It is intended for the original sensor position after the catalytic converter, not the upstream sensor at the engine.

The attached harness and connector provide a replacement for the specified original application without converting to a universal splice-in sensor. Confirm the vehicle's emissions specification and sensor position before ordering; Federal-emissions and SR5 applications use different sensors.

Key Features

• Connector-equipped harness connects to the original downstream sensor wiring.
• Unheated zirconia sensing element matching the specified two-lead sensor configuration.

Vehicle Fitment

Toyota Corolla — AE92

• 1989–1991: GT-S coupe (U.S.-Market) / 4A-GE / California emissions / No. 2 downstream oxygen sensor.

Fitment Notes

• Fits the California-emissions No. 2 sensor position after the catalytic converter. It is not a replacement for the upstream sensor.
• Not for Federal-emissions GT-S or SR5 applications. Do not select this sensor by engine size or wire count alone.
• Fitment is limited to the original exhaust and wiring configuration; engine swaps, altered emissions systems and universal sensor conversions require separate evaluation.
