J.C. Whitney JRT96090008 Heated Upstream Oxygen Sensor 4-Wire OEM Replacement

The J.C. Whitney JRT96090008 is a direct-fit, OEM-replacement heated upstream oxygen sensor designed for the Toyota Land Cruiser (1995–1997) and Lexus LX450 (1996–1997). This 4-wire heated oxygen sensor (HO2S) restores proper air-fuel ratio monitoring to your vehicle's engine management system, helping maintain fuel efficiency and reduce harmful emissions.

Key Features:

• OEM Replacement: Engineered to meet or exceed original equipment specifications for a reliable, like-factory fit
• Heated Design: Built-in heating element reaches operating temperature faster, improving cold-start performance and sensor accuracy
• 4-Wire Construction: Two heater circuit wires and two sensor signal wires for precise air-fuel mixture feedback to the ECU
• Upstream Position: Mounts before the catalytic converter to monitor combustion efficiency and enable closed-loop fuel control
• Direct Fit: Designed as a plug-and-play replacement — no splicing or modification required
• Durable Materials: Built to withstand high exhaust temperatures and long-term exposure to road conditions

A faulty upstream oxygen sensor can trigger a check engine light (CEL), cause poor fuel economy, rough idling, and failed emissions tests. Replacing it with the JRT96090008 restores accurate exhaust gas monitoring and closed-loop engine operation. Compatible with Toyota Land Cruiser 1995–1997 and Lexus LX450 1996–1997 applications.
