Description
LS4169 Front Lambda (Oxygen) Sensor – Before Catalytic Converter
The LS4169 front lambda (oxygen) sensor is positioned before the catalytic converter and measures exhaust oxygen content to help the ECU control air-fuel mixture accurately. A faulty upstream oxygen sensor can lead to higher fuel consumption, rough running, or an engine light.

- Jeep Compass 2.4 (ED3 / EGD) 2009–2017 — front sensor before catalytic converter
- Jeep Patriot 2.4 (ED3 / EGD) 2009–2017 — front sensor before catalytic converter
Position
- Fitting position: Front (upstream)
- Location: Before catalytic converter
Notes for Fitment
- Confirm engine code (ED3 / EGD) and that you need the upstream sensor (before cat), not the downstream sensor.
- If you’re unsure, send your VIN and we’ll verify the correct sensor before dispatch.
