In the 2001 six-cylinder Toyota Solara, the oxygen sensors are located in the exhaust system: one before the catalytic converter (upstream) and one after it (downstream). To determine which sensor may need replacement, you can check for diagnostic trouble codes (DTCs) using an OBD-II scanner; codes related to oxygen sensor performance issues will indicate a faulty sensor. Additionally, physical inspection for signs of damage or contamination can help identify a failing sensor. If the vehicle exhibits poor fuel economy or rough idling, these may also suggest a malfunctioning oxygen sensor.
