Oxygen Sensor Upstream Air-Fuel Ratio Lambda for Toyota Camry ES350 RX350 RX450h
Upgrade your vehicle’s fuel-management performance with the IWOKPHD Oxygen Sensor Upstream Air-Fuel Ratio Lambda, designed for Toyota Camry ES350 RX350 RX450h and a wide range of Toyota and Lexus models. This upstream oxygen sensor (before the catalytic converter) delivers precise lambda feedback to your engine control unit, helping maintain an optimal air-fuel balance for smoother driving, better idle stability, and lower emissions. Built as a heating-type, piezoelectric sensor, it responds quickly in cold starts and under changing driving conditions, ensuring your engine runs efficiently from first crank to highway cruising.
Compatible with a broad set of applications including Lexus ES350 2008-2011, RX350 2007-2009, RX450H 2010, Toyota 4Runner 2010, Avalon 2008-2011, Camry 2008-2011, Highlander 2008-2010, RAV4 2006-2012, Sienna 2011, Tacoma 2011-2012, and Venza 2009-2011, this sensor is engineered to fit the upstream (pre-cat) position on the right side for many trims. The included OEM numbers and part numbers—such as 89467-33180, 8946733180, 89467-42120, 8946742120, 8946742090, 8946760050, 8946704070, and related variants—reflect broad cross-compatibility, making it a reliable, drop-in replacement for several Toyota/Lexus models listed in the applications.
Replacing a degraded upstream O2 sensor helps restore accurate fuel trims, reduces rough idle, improves throttle response, and supports cleaner exhaust emissions — valuable for passing inspections and maintaining peak fuel efficiency. The upstream sensor plays a critical role in sensing exhaust gas composition early in the stream, allowing the ECU to fine-tune the air-fuel mix in real time for optimal combustion.
All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.
