J.C. Whitney JARBM960918 Heated Downstream Oxygen Sensor 4-Wire OEM Replacement

The J.C. Whitney JARBM960918 is an OEM-replacement heated oxygen sensor designed for downstream front installation. This 4-wire heated O2 sensor delivers accurate exhaust gas monitoring to help maintain optimal fuel trim and emissions performance, replacing a worn or failed factory sensor with a direct-fit solution.

Key Features:

• Heated design — integrated heating element brings the sensor to operating temperature quickly, improving cold-start accuracy and reducing emissions
• 4-wire configuration — two heater wires and two signal wires for plug-and-play compatibility with factory wiring harness
• Downstream front position — monitors catalytic converter efficiency, supporting proper OBD-II diagnostic function
• OEM replacement — engineered to meet original equipment specifications for accurate air/fuel ratio feedback
• Durable construction — protective housing and high-temp sensor tip designed to withstand harsh exhaust environment temperatures

Installing a fresh oxygen sensor restores proper closed-loop fuel control, helping eliminate check engine lights related to O2 sensor codes (P0136, P0141, and related downstream sensor DTCs). The J.C. Whitney JARBM960918 is a reliable, cost-effective alternative to dealer-sourced parts.
