J.C. Whitney JRS96090006 Downstream Heated Oxygen Sensor 4-Wire OEM Replacement

The J.C. Whitney JRS96090006 is a direct-fit, heated downstream oxygen sensor designed as an OEM-quality replacement. Featuring a 4-wire heated design, this sensor is engineered for precise fit and reliable performance, restoring proper exhaust monitoring and closed-loop feedback to the engine control unit (ECU).

The downstream O2 sensor is positioned after the catalytic converter and plays a key role in the vehicle's OBDII emissions monitoring system. A failing downstream sensor can trigger a Check Engine Light, reduce fuel efficiency, and lead to failed emissions inspections. Replacing it with this direct-fit unit helps restore proper engine management and catalytic converter efficiency monitoring.

Key Features:

• Direct-fit OEM replacement — engineered to match original equipment specifications for form, fit, and function
• Heated 4-wire design — integrated heater circuit allows the sensor to reach operating temperature quickly for faster closed-loop response
• Threaded mounting style — installs into the existing bung in the exhaust pipe using standard tools
• Female connector — plugs directly into the factory wiring harness with no modification required
• OEM cross-reference numbers: 1A6018861, 19060002, 24843, 234-4227, 250-24291, OS5162

Backed by J.C. Whitney's 1-year, unlimited-mileage warranty, this oxygen sensor delivers a cost-effective, reliable solution for restoring exhaust system performance.
