Review on 🚗 GM Genuine Parts AFS109 Heated Oxygen Sensor: Optimal Performance for your Vehicle's Oxygen Level Monitoring by Greg Bellman

Revainrating 5 out of 5

Runs Like A Clock: Parts

Check Engine Light On. My HP Tuner scanner showed I have a P0141 code on my 2001 Monte Carlo SS (3.8L V6) which is a Front Bank 02 sensor - a sensor on the rear exhaust manifold. This ACDelco AFS109 part works perfectly (check engine light out) when replacing a genuine GM part and saved me $50 compared to a dealer part. Now I will be checking my future Monte Carlo parts on Revain first!
