NTK 24567 oxygen sensor for the 2001-2003 Toyota Highlander V6 3.0L and other vehicles feeds exhaust oxygen readings back to the engine computer. This downstream sensor helps the OBDII system watch catalytic converter efficiency, and NTK controls its ceramic element from raw material to finished product.
A check engine light or poorer fuel economy can mean the sensor is worn, though a damaged harness or an exhaust leak may be behind them instead. With the engine off and cool, look over the harness and connector for chafing or melted insulation before replacing the sensor.
The 1999-2003 Lexus RX300 V6 3.0L and the 1993-1998 Toyota Supra 6-cylinder 3.0L take it too. This listing is one downstream sensor, and the 2001-2003 Toyota Highlander V6 3.0L takes one.
