Common Uses

• Replacing a failed upstream or downstream oxygen sensor
• Addressing check engine light concerns related to oxygen sensor performance
• Restoring proper air-fuel ratio feedback to the engine control system
• Correcting poor fuel economy caused by inaccurate exhaust readings
• Replacing a damaged sensor connector or worn harness on the original unit

Installation Notes

Verify the sensor position before ordering, since this part is used in upstream, downstream, upstream right, and upstream left locations depending on the vehicle. Confirm the threaded mounting style, 4-wire connector, and harness length against the original sensor before installation. For Mercedes-Benz E300, E350, E550, and related models, match the exact application listed above to ensure proper placement.
