J.C. Whitney JRS96090014 Downstream Heated Oxygen Sensor 4-Wire OEM Replacement

The J.C. Whitney JRS96090014 is a direct-fit OEM replacement downstream heated oxygen sensor designed for the Suzuki Swift (1996–2001) and Geo/Chevrolet Metro (1998–2001). This 4-wire heated sensor restores proper exhaust gas monitoring after the catalytic converter, allowing the engine control module (ECM) to accurately assess catalytic converter efficiency and maintain optimal fuel trim.

Replacing a faulty downstream O2 sensor can resolve check engine lights triggered by catalyst efficiency codes (P0420/P0430) and help ensure your vehicle passes emissions testing. The integrated heating element allows the sensor to reach operating temperature quickly, even during cold starts, ensuring accurate readings from the moment the engine fires.

Key Features:

• Direct OEM replacement — plug-and-play fitment with no modifications required
• 4-wire heated design for fast warm-up and consistent signal accuracy
• Downstream (post-catalytic converter) positioning for catalyst monitoring
• Manufactured to meet or exceed original equipment specifications
• Helps resolve P0420/P0430 catalyst efficiency diagnostic trouble codes
• Restores proper closed-loop fuel management and emissions compliance

The J.C. Whitney JRS96090014 oxygen sensor is engineered to deliver reliable, long-term performance as a cost-effective alternative to dealer-sourced parts for the Suzuki Swift and Metro platforms.
