J.C. Whitney JARBL960902 Heated 4-Wire Upstream Oxygen Sensor OEM Replacement

The J.C. Whitney JARBL960902 is a direct-fit OEM replacement heated oxygen sensor designed for use on the upstream (pre-catalytic converter) position. Built to restore proper air/fuel mixture monitoring, this sensor helps your vehicle's ECU maintain optimal fuel delivery and emissions performance.

Key Features:

• Heated Design: 4-wire heated construction allows the sensor to reach operating temperature quickly, improving cold-start accuracy and reducing emissions
• Upstream (Pre-Cat) Position: Installs before the catalytic converter to monitor exhaust gases directly from the engine
• OEM Replacement: Engineered to match the fit, form, and function of the original factory sensor
• 4-Wire Configuration: Two heater circuit wires and two signal wires for full compatibility with factory wiring harness
• Direct Fit: No modifications required for a straightforward installation

Replacing a faulty oxygen sensor with the JARBL960902 can restore fuel economy, eliminate a check engine light triggered by O2 sensor fault codes, and help the engine run cleanly and efficiently. Ideal for restoring factory emissions performance on compatible Lexus vehicles.
