Replacement ARBS960917 Heated Threaded-In Oxygen Sensor - 4-Wire

The Replacement ARBS960917 is a heated, 4-wire, threaded-in oxygen sensor (O2 sensor) designed as a direct OE replacement for select Cadillac and Pontiac vehicles. This sensor monitors exhaust oxygen content, providing continuous closed-loop feedback to the engine control module (ECM) to maintain the optimal air-fuel ratio and reduce harmful emissions.

Key Features:

• Type: Heated oxygen sensor (HO2S) for faster warm-up response and accurate readings
• Configuration: 4-wire design for precise signal and heater circuit control
• Mounting Style: Threaded-in type for straightforward installation
• Thread Size: M18 x 1.5 standard thread
• Connector: Male connector
• Fit: Direct-fit OE replacement — no modifications required
• Manufacturer Part Number: ARBS960917

This oxygen sensor is engineered to restore proper emissions control and fuel management performance. Its heated element ensures the sensor reaches operating temperature quickly, helping the ECM achieve closed-loop fuel control sooner for improved efficiency and reduced emissions.
