DriveWire ARBC960901 Unheated 1-Wire Upstream Oxygen Sensor Threaded-In

The DriveWire ARBC960901 is an OEM-replacement upstream oxygen sensor designed as a direct-fit solution for compatible GM vehicles. This unheated, 1-wire sensor installs in the threaded bung located before the catalytic converter on either the driver or passenger side of the exhaust system.

As a 1-wire unheated oxygen sensor, it relies on exhaust heat to reach operating temperature and uses a single signal wire with grounding achieved through the sensor body. This design is consistent with the factory configuration found on many mid-1980s through mid-1990s GM applications.

Key Features:

• Type: Unheated, 1-Wire Zirconia Oxygen Sensor
• Installation Type: Threaded-In (bung-mounted)
• Location: Before Catalytic Converter (Upstream / Bank 1 Sensor 1)
• Position: Driver or Passenger Side
• Design: OEM replacement — matches original factory specifications
• Quantity Sold: Single sensor

Restoring proper oxygen sensor function helps the engine control module (ECM) accurately regulate the air-fuel mixture, which is essential for fuel efficiency, emissions compliance, and overall engine performance. The DriveWire ARBC960901 is built to meet or exceed original equipment standards for a reliable, straightforward replacement.
