Review on 🔥 Enhanced AFS105 Heated Oxygen Sensor by GM Genuine Parts by Bill Wieser

It fits my 97 Blazer perfectly and works great. It only took 15 minutes to remove and replace the old oxygen sensor. The Check Engine Light (MIL) will go off after a few successful drive cycles with the ECU not detecting any problems, or if you have a scan tool you can clear the DTC set in the ECU which will clear the Check Engine Light (MIL). , and if the O2 sensor was your real problem, the light shouldn't come back on. If it comes back, you haven't diagnosed the problem and you probably replaced a good oxygen sensor. Don't blame the sensor for a bad mechanical diagnosis. Check Engine Lights are symptom indicators only, they don't tell you how to fix the car, even with an OBD2 code reader. Do your research before you buy. The biggest problem with this site is people buying the wrong product because they haven't researched it and then giving a bad review because it doesn't fit. Read! read! read! and then read! little more before ordering.
