Shop Saturn LW300 Replacement Oxygen Sensor

Your Saturn L300 is equipped with four oxygen sensors, two upstream and two downstream. Upstream refers to the sensors positioned between the engine and the catalytic converter. Downstream refers to those placed after the cat converter, where they are able to gather data relating to the oxygen content of the exhaust gases after they have been catalyzed. The upstream sensors, one that monitors the left bank of engine cylinders and one that monitors the right side, feed info to the engine control computer regarding O2 content of the exhaust before it enters the catalytic converter. The computer uses this information to continually adjust the air/fuel mixture being burned in the combustion chambers. Bad oxygen sensors need to be replaced. They affect fuel consumption, emissions, power and performance. PartsGeek.com has replacement oxygen sensors for your 2001-2003 Saturn L300, from Walker, Delphi, Bosch and Denso, the original equipment manufacturer for these parts.
