Replacement ARBP960904 Heated Oxygen Sensor 4-Wire Threaded-In O2 Sensor

The Replacement ARBP960904 is a direct-fit, heated oxygen sensor designed as an OEM-quality replacement for vehicles requiring a 4-wire, threaded-in style O2 sensor. This sensor monitors exhaust gas oxygen levels and sends real-time data to the engine control module (ECM), enabling precise fuel trim adjustments for optimal combustion efficiency.

Key Features:

• Heated Design: Built-in heating element allows the sensor to reach operating temperature quickly, reducing cold-start emissions and improving fuel economy
• 4-Wire Construction: Two heater circuit wires and two signal wires ensure accurate readings and compatibility with OEM wiring harnesses
• Threaded-In Type: Standard threaded bung mount for straightforward installation using a conventional oxygen sensor socket
• OEM Replacement Quality: Engineered to meet or exceed original equipment specifications for reliable, long-term performance
• Direct-Fit Design: Drop-in replacement with correct connector and thread pitch to match the original sensor

Replacing a faulty oxygen sensor restores proper air/fuel ratio management, helping eliminate rough idle, poor fuel economy, and failed emissions tests. The ARBP960904 is a cost-effective solution for restoring factory-level performance without the dealership price tag.
