J.C. Whitney JARBP960910 Heated Upstream Oxygen Sensor 4-Wire OEM Replacement

The J.C. Whitney JARBP960910 is a direct-fit, OEM-replacement oxygen sensor designed for select Chevrolet Silverado and Impala applications. This heated, 4-wire upstream (pre-catalytic converter) O2 sensor restores proper air/fuel mixture feedback to the engine control module (ECM), helping maintain optimal combustion efficiency, fuel economy, and emissions compliance.

Key Features:

• OEM Replacement: Engineered to match the original sensor's fit, form, and function for a hassle-free swap
• Heated Design: Integrated heating element allows the sensor to reach operating temperature quickly, reducing cold-start emissions and improving engine response
• 4-Wire Construction: Two heater circuit wires and two signal wires for precise air/fuel ratio monitoring
• Upstream Position: Mounts before the catalytic converter to provide real-time exhaust gas feedback to the ECM
• Plug-and-Play Installation: Direct connector match eliminates the need for splicing or adapters
• Helps Resolve Fault Codes: Addresses common diagnostic trouble codes (DTCs) such as P0130, P0135, and related O2 sensor circuit faults

Replacing a faulty oxygen sensor with the JARBP960910 can restore fuel efficiency, reduce harmful exhaust emissions, and eliminate the check engine light associated with upstream O2 sensor failures. This sensor is a reliable, cost-effective solution for maintaining your vehicle's emissions and performance systems.
