Oxygen Sensor Upstream Air-Fuel Ratio Lambda for Toyota Camry Avalon Sienna

Upgrade your vehicle’s air-fuel management with the IWOKPHD Oxygen Sensor Upstream Air-Fuel Ratio Lambda, designed for Toyota Camry, Avalon, Sienna and Solara models (upstream position). This heated, upstream oxygen sensor continuously monitors the exhaust gas’s lambda value before the catalytic converter, delivering precise feedback to the engine control unit. The result is cleaner combustion, improved fuel economy, smoother idle, and reduced emissions—especially during cold starts and load changes where a fast sensor response matters most.

Compatible with multiple 3.0L V6 applications, this sensor aligns with OE references such as 89467-41040 and its related variants (including 89467-41030, 234-9021, 2349021, and 89467-33030). Fitment covers Lexus ES300 (2000–2001), Toyota Avalon (2000–2004), Toyota Camry (2001), Toyota Sienna (2000–2003), and Toyota Solara (2001–2003), with two sensors required per vehicle for upstream installation. It’s described as a perfect match for the car and delivers stable installation, making it a reliable choice for ongoing maintenance or performance restoration.

Each unit is a 100% brand-new IWOKPHD part, thoroughly tested before shipment to ensure consistent performance. The upstream design and heating capability help maintain accurate readings across temperature swings, contributing to optimal engine operation and compliance with emission standards. This description reflects the product’s stated features and compatibility to help you make an informed replacement decision.

Benefits & Tips

• Improve fuel economy and throttle response by ensuring the ECU receives accurate pre-cat oxygen readings at all engine temperatures.
• Restore stable idle and smoother drive in vehicles that previously showed fluctuating air-fuel ratios or intermittent sensor signals.
• Use as a direct replacement for worn OEM sensors with OE equivalents—ideal for preventative maintenance on 3.0L V6 Toyota/Lexus setups.
