DriveWire ARBK960902 Downstream Heated Oxygen Sensor After Catalytic Converter - 4-Wire

The DriveWire ARBK960902 is a direct-fit, OEM-replacement downstream oxygen sensor designed for precise exhaust monitoring after the catalytic converter. Engineered as a plug-and-play replacement, this sensor restores proper air-fuel ratio feedback to the vehicle's Powertrain Control Module (PCM), helping maintain optimal engine efficiency and emissions compliance.

This sensor features a 4-wire heated design — two wires for the sensing element (signal and ground) and two wires for the internal heater circuit. The integrated heater brings the sensor to operating temperature quickly, enabling faster closed-loop engine operation and more accurate exhaust readings regardless of driving conditions.

Key Features:

• Type: Heated oxygen sensor (HO2S) — Bank 1, Sensor 2 (B1S2)
• Wiring: 4-wire configuration with 14.75 in. wire length
• Position: Downstream — after catalytic converter
• Mounting: Threaded-in type with 7/8 in. hex size for standard installation
• Fit: Direct OEM replacement for proper connector and thread compatibility
• Sold: Individually

The ARBK960902 is a straightforward, no-modification replacement that installs using standard tools. Its threaded-in design and factory-matched connector ensure a secure, reliable fit without splicing or adapter hardware.
