Mitsubishi Outlander 2006 3.0L Front Right Oxygen Sensor 1588A081 Direct Replacement

When 2006 Mitsubishi Outlander 3.0L idles roughly, fuel consumption climbs, MIL is on and reports oxygen sensor fault codes, the front-right oxygen sensor (1588A081) has aged and failed. This sensor monitors oxygen content in exhaust and feeds the ECU for precise air-fuel control; replacement with OEM 1588A081 fits 2006 Outlander 3.0L. Install on a cold engine; avoid contact of sensor harness with exhaust hot spots; clear fault codes and road-test after installation.
