J.C. Whitney JRD96090005 Heated Downstream Oxygen Sensor 4-Wire OEM Replacement

The J.C. Whitney JRD96090005 is a heated, 4-wire downstream oxygen sensor designed as a direct OEM replacement. This sensor monitors exhaust gases after the catalytic converter, providing critical feedback to the engine control module (ECM) to ensure optimal fuel delivery, emissions compliance, and engine performance.

Key Features:

• OEM Replacement: Direct fit replacement for the original factory oxygen sensor — no modifications required
• Heated Design: Integrated heater element allows the sensor to reach optimal operating temperature quickly, improving cold-start emissions and fuel efficiency
• 4-Wire Construction: Two heater wires and two signal wires for precise, reliable exhaust gas measurement
• Downstream Position: Designed for the post-catalytic converter (downstream) location to monitor catalytic converter efficiency and satisfy OBD-II requirements
• Durable Build: Constructed to withstand high exhaust temperatures and harsh under-vehicle conditions

Replacing a faulty downstream oxygen sensor can resolve check engine lights related to O2 sensor circuit codes (P0136–P0141) and restore proper emissions system function. The JRD96090005 is a straightforward, plug-and-play solution for restoring your vehicle's exhaust monitoring system to factory specification.
