Official Dodge Website What is an Oxygen sensor? AutoTrader.com      CARFAX      edmonds.com      Kelley Blue Book '04 Dodge Stratus SXT 2.7L Oxygen Sensor Information This article will tell you how you can self test for oxygen sensor diagnostic codes and locations of the oxygen sensors on a 2004 Dodge Stratus SXT 2.7L engine. If you turn the key on three times without starting the vehicle the third time you will see code numbers located where the odometer is. (See list below for code reason.) This will not clear the codes only give you a reading. Right bank is located near the firewall; cylinder 1 is on the left side facing engine, closest to cylinder 1 will be right bank (upstream) sensor 1 at the catalytic converter, below that on the exhaust pipe is right bank (downstream) sensor 2. Left bank is located near front of car; cylinder 2 is on the left side facing engine, closest to cylinder 2 will be left bank (upstream) sensor 1, below that on the exhaust pipe is left bank (downstream) sensor 2.
