J.C. Whitney JH960916 Downstream Heated Oxygen Sensor 4-Wire OEM Replacement

The J.C. Whitney JH960916 is a heated, 4-wire downstream oxygen sensor designed as a direct OEM replacement for select Acura TL and Acura RL models. It cross-references OEM part number 36531-P2E-A01, ensuring a precise fit and reliable performance without modification.

Downstream (post-catalytic converter) oxygen sensors play a critical role in monitoring catalytic converter efficiency and providing feedback to the engine control unit (ECU). A faulty downstream O2 sensor can trigger a check engine light, reduce fuel efficiency, and cause failed emissions testing. Replacing it with a quality unit restores proper closed-loop fuel management and emissions compliance.

Key Features:

• Heated 4-Wire Design – Integrated heater circuit allows the sensor to reach optimal operating temperature quickly, improving accuracy and cold-start performance
• OEM Cross-Reference: 36531-P2E-A01 – direct replacement with no modification required
• Downstream Position – Monitors exhaust output after the catalytic converter for accurate emissions feedback
• Direct-Fit Connector – Plug-and-play installation with factory wiring harness connector
• Restores Fuel Efficiency – Corrects rich/lean conditions caused by a failing sensor
• Clears Check Engine Codes – Resolves OBD-II fault codes related to downstream O2 sensor performance

This sensor is a reliable, cost-effective alternative to dealer-sourced OEM parts, delivering equivalent fit, form, and function for Acura TL (1995–1998) and Acura RL (1996–2004) applications.
