GM Genuine Parts AFS105 (19178918) Heated Oxygen Sensor

I have a 1996 2 door tahoe that had a check engine light with the code PO155. This code is a heat circuit code for your 02 sensor on bank 2 sensor 1. I replaced this sensor and it fixed the problem and cleared the check engine light. The sensor is good quality and like OEM. Fit just like stock. Installation was smooth as well. You'll just need a 22mm wrench. Plug unclips and it comes with new plastic fastner to clip into bracket. Worth every penny. The 105 sensor is for bank 1 and 2, sensor 1 on both driver and passenger side before the cat. The 106 sensor is for the 2 sensors after the cat on both driver and passenger sides. When I change these 105 sensors, I always do both sides at the same time on banks 1 and 2, sensor 1 on both sides before the cat.

I replaced the upstream sensors in my 1998 Chevy Blazer after the computer started throwing O2 codes, P0131 and then P0135 under hard acceleration. For the last several thousand miles, the engine had started running very rough, the idle would slowly creep upward if the truck was left alone, it was pinging and hard to start. I knew the old sensors were definitely bad when I removed them because they were caked with a thick white dust. According to the service manual, this is a tell-tale of a dead O2. Well, I'm not complaining, the originals were in there for 200k miles. After replacing these sensors, the engine starts quicker, runs very smooth, no more pinging, and the POWER. I used to push the accelerator to the floor on the hill in my neighborhood, at the top of the hill, I would be going 20MPH. Now, I only push the pedal 1/2 way down and I am going 50 a the top! This thing spins tires through first and all the way to the top of second gear now if I'm not careful. This is with a brand new set of Firestone Transforce A/T tires that are a size bigger than the original. Only time will tell if they last as long as the originals, but one thing is for certain: installing these was like taking 10 years off the age of this truck.

Got an error code for bank 2 sensor 1 oxygen sensor (pre-cat) in my 1997 Chevy Silverado C1500 5.7L. Got the part, looks a little different than the original but matches images from GM/ACDELCO websites. Replaced it and my check engine light is gone and my truck runs better. Would recommend ordering these parts from Amazon. It’s been a week and so far no issues, no additional codes.

This fit my 97 Blazer perfectly and has been working great. Only took 15 minutes to remove and replace the old o2 sensor. Check engine light (MIL) turns off after several successful drive cycles with out the ECU detecting any problems or if you have a scan tool you can erase the DTC's set in the ECU and that will clear the check engine light (MIL) and if the o2 sensor was your true problem then the light should not come back on. If it comes back then you miss diagnosed the problem and you probably changed a good o2 sensor. Don't blame the sensor for poor a mechanical diagnoses. Check engine lights are only indicators to symptoms they don't tell you how to fix the car even with a OBD2 code reader. Do your research before you buy. The biggest problem on this site are people who buy the wrong item because they did not research then give the item a bad review because it did not fit. Read! read!! read!!! and then read!!!! some more before you order.

good

1999 gmc jimmy 4.3 4x4 got the : P0135 Code : bank 1 sensor 1 bad O2 heater sensor . for the price I just decided to change all three of them at the same time with this one. for both the up and down. its 2 Upstream 1 Downstream. I cleared the check engine light. changed them. crank the car and let it warm up for 10 minutes then drove it for about 20 miles. OBD 02 said still not ready. so I waited till it was "cold real early in the morning" started the car fast didn't let it warm up and drove it a couple miles .OBD 02 then 'finally' changed to ready. so I started it back up and just let it idle for 30 minutes. drove it to the shop didn't shut it off "inspection granite" Happy Customer. good product fair price. .. ps for the love of God use some anti seize on the threads people. and yes the anti seize will burn off smoke and smell like your cars on fire for the first time or two you drive it afterwards.
