Toyota Air-Fuel Ratio Oxygen Sensor 89465-52380 Replaces 89465-20810

Toyota air-fuel ratio oxygen sensor, OEM number 89465-52380, perfectly replaces 89465-20810, fits 2009-2015 Camry 2.5L, 2010-2016 RAV4 2.5L, and 2012-2018 Highlander 3.5L. Core function is precise monitoring of exhaust oxygen content and feeding ECU to adjust fuel injection and emission controls. Replacement difficulty moderate; use a dedicated oxygen sensor socket and apply anti-seize to ensure a tight installation and stable signal transmission.
