Shop Saturn L300 Replacement Oxygen Sensor

Saturn L300 owners receiving error codes relating to their oxygen sensors, codes such as P0050, P0150 and P0030, may be required to replace one or more of their vehicle's O2 sensors in order to fix the problem. Saturn L300s were made with four O2 sensors installed, two upstream and two downstream. While the two upstream sensors require the same part for replacement, the two downstream sensors are different parts, designated left and right, for a total of three part numbers but four total units, if all O2 sensors are to be replaced. PartsGeek.com has more than a dozen models of oxygen sensors designed to fit the Saturn L300, model years 2001, 2002, 2003 and 2005. This includes units manufactured by Bosch, Denso and Delphi, all of which offer OEM parts plus Walker Products Inc. All are made to work with Saturn L300s with V6, fuel-injected, naturally aspirated gas engines.
