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.

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.

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.

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.

This vendor is selling an ACDelco 0MOS6020 Oxygen sensor in place of the ACDelco AFS105. Initially, I was going to return the product, but after some research I determined that the connection and pinout of the connector is the same as the AFS105. The AFS105 has a heater resistance of about 15ohm, the 0MOS6020 is about 11.4 ohm, so it is well within spec. After verifying fitment, pinout, and resistance, I have kept and installed these on my '96 Chevy Silverado 5.7L and work fine. You can search on Herko Automotive website for more information on the ACDelco 0MOS6020. 4 stars because the product works but is not an actual AFS105 unit.

2000 4.3 v6 o2 sensor works as should. Same part as the one removed after many years. Installed almost a month ago, getting slightly better gas mileage. Comes with copper lubricant.

Simple easy OEM replacement for my 98 suburban.

I bought this GM AC Delco for my 1997 Chevy C1500 5.0L, been a great one, what's weird now is, Amazon says this doesn't fit my truck, and I've ran AFS105 at different auto part places and it fits my truck, so if you have a truck like mine, or the K1500, it WILL WORK, anything the year 2000 and up, it will NOT WORK.

Used this heated sensor to upgrade the single wire o2 sensor on a 1992 454 tbi engine. Selected this one based on price . Works flawlessly. Goes into and stays in closed loop quickly, even in sub zero weather . A Single wire sensor will only last 60000 km tops , then mpg tanks. Cut end , spliced wires . 1 - blue o2 wire , 2 - switched positive for heater ,element . All the rest crimp together and ground. Excellent upgrade . Also replace CTS as part of a full tune up . Quality part I assume would work perfect for its intended use.

Le quedó muy bien a una GMC Jimmy 4x4 se le borro el testigo se ve de buena calidad

Todo muy bien , es el original solo que los otros sensores he tenido mala suerte y me mandan otros que no coinciden con la fotografía publicada pero todo muy bien lo recomiendo
