J.C. Whitney JN960917 Downstream Heated Oxygen Sensor 4-Wire OEM Replacement

The J.C. Whitney JN960917 is a direct-fit OEM replacement downstream oxygen sensor designed for compatible Nissan Maxima and Sentra models. This heated, 4-wire oxygen sensor restores proper exhaust emissions monitoring, helping your vehicle maintain optimal fuel trim and pass emissions testing.

Mounted downstream of the catalytic converter, this sensor monitors catalytic converter efficiency and reports data to the engine control unit (ECU). The built-in heater element allows the sensor to reach operating temperature quickly, ensuring accurate readings even during cold starts and short trips.

Key Features:

• Direct OEM Replacement — engineered to match original equipment fit and function
• Downstream / Post-Catalyst Position — monitors catalytic converter efficiency
• Heated Design — integrated heater element for faster warm-up and accurate readings
• 4-Wire Construction — two heater wires, one signal wire, one ground wire for precise signal output
• Threaded-In Mounting Type — threads directly into the factory bung in the exhaust system
• Restores proper air/fuel mixture feedback and emissions compliance

Replacing a faulty oxygen sensor can resolve a lit check engine light, poor fuel economy, and failed emissions inspections. The J.C. Whitney JN960917 is a reliable, cost-effective solution to restore your vehicle's exhaust monitoring system to factory specification.
