J.C. Whitney JDI96090002 Heated Upstream Oxygen Sensor 4-Wire OEM Replacement

The J.C. Whitney JDI96090002 is a heated, 4-wire upstream (pre-catalytic converter) oxygen sensor designed as a direct OEM replacement for select Infiniti Q40, Infiniti Q50, and Nissan Altima vehicles. This sensor monitors the air-fuel mixture entering the catalytic converter, providing real-time feedback to the engine control module (ECM) to optimize combustion efficiency, fuel economy, and emissions output.

Key Features:

• OEM Replacement: Engineered to match original equipment specifications for a direct fit and reliable performance
• Heated Design: Integrated heating element allows the sensor to reach operating temperature quickly, reducing warm-up emissions and improving cold-start performance
• 4-Wire Construction: Features a dedicated heater circuit (2 wires) and signal circuit (2 wires) for precise and stable oxygen level readings
• Upstream Position: Installs in the pre-catalyst position in the exhaust stream for accurate air-fuel ratio monitoring
• Plug-and-Play Installation: Designed to connect directly to the factory wiring harness without modification
• Helps Resolve DTCs: Addresses common diagnostic trouble codes related to oxygen sensor faults (P0130–P0167 range)

Restoring a faulty oxygen sensor with the J.C. Whitney JDI96090002 can improve throttle response, restore fuel efficiency, and ensure your vehicle passes emissions testing. Built to meet the demands of everyday driving for Infiniti Q40 (2015), Infiniti Q50 (2014–2018), and Nissan Altima (2015–2017) applications.
