🔥 Enhanced AFS105 Heated Oxygen Sensor by GM Genuine Parts Review

This is the third one I've bought for our 99 Blazer. Bought two first to replace the pre-cat originals and they worked great. I've decided to only buy the third one that goes after the cat as it has 180,000. However, it arrived defective. The ground wire has not been welded to the sensor. There was a trace of sweat, but it didn't stick. I only fixed it, welded it, because it was easier for me to do than to mess around with sending it back. Works well.

This supplier sells ACDelco 0MOS6020 oxygen sensor instead of ACDelco AFS105. Originally I wanted to return the product, but after doing some research I found that the connector connector and pinout is the same as the AFS105. The AFS105 has a heater resistance of around 15 ohms, the 0MOS6020 has a heater resistance of around 11.4 ohms so within spec. After checking fit, pinout and resistance I saved them and installed them on my 1996 Chevy Silverado 5.7L and they work fine. For more information

I ordered this (AC DELCO AFS105) for my 1997 C2500 5.7 liter. Revane initially said they fit. When they arrived they didn't fit. After reading more, I found that the front oxygen sensors are different depending on the transmission. I assume this is one of the differences between 7400 GVW and 8600 GVW trucks. After figuring this out and changing the transmission spec on my truck in My Garage from 4l60e to 4l80e, Revain said no more that they fit and I ordered some of these later I hope it fits…

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…

1999 gmc jimmy 4.3 4x4 got: p0135 code: row 1 sensor 1 bad O2 heater sensor. For this price I decided to trade all three at once for this one. for above and below. its 2 upstream 1 downstream. I cleared the check engine light. they changed. I started the car and let it warm up for 10 minutes, then I drove 20 km. OBD 02 said not done yet. So I waited until it was "very cold early morning", quickly started the car, let it warm up and drove a few miles .OBD 02, then it "finally" went into starting
