Built to GM OE standards with a durable heated element for fast response, it guarantees a perfect fit and reliable operation backed by a 24-month unlimited mile warranty. ## Description GM Genuine Parts Oxygen (O2) Sensors are designed, engineered, and tested to rigorous standards, and are backed by General Motors. These sensors are special feedback sensors on your vehicle's exhaust system and measure the proportion of oxygen in exhaust gases. Using this measurement, the engine control module (ECM) can adjust the air/fuel ratio to near the optimal value of 14.7:1. At this ratio, engine performance, emissions, and fuel economy are all optimized. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE). Review: Fixed check engine PO155, New sensor 105 - 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. Review: Great little fix for a tired old vehicle - 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. ## Features - Detect oxygen content in the exhaust gases to optimize emissions and fuel economy - GM-recommended replacement part for your GM vehicle’s original factory component - Offering the quality, reliability, and durability of GM OE - Manufactured to GM OE specification for fit, form, and function ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0013FWACW | | Best Sellers Rank | #214,292 in Automotive ( See Top 100 in Automotive ) #915 in Automotive Replacement Oxygen Sensors | | Brand | GM GENUINE PARTS | | Brand Name | GM GENUINE PARTS | | Customer Reviews | 4.7 out of 5 stars 616 Reviews | | Global Trade Identification Number | 00707773397404, 40707773397402 | | Included Components | Oxygen Sensor | | Item Dimensions | 7.6 x 2 x 2.3 inches | | Item Type Name | Oxygen Sensor | | Item dimensions L x W x H | 7.6 x 2 x 2.3 inches | | Manufacturer | ACDelco | | Material | Ceramic, Metal | | Material Type | Ceramic, Metal | | Maximum Supply Voltage | 12 Volts (DC) | | Model | AFS105 | | Mounting Type | Flange Mount | | Output Type | Push-Pull | | Specific Uses For Product | Oxygen Sensor | | Style | Modern | | Style Name | Modern | | UPC | 707773397404 036666931587 | | Unit Count | 1.0 Count | | Upper Temperature Rating | 1292 Degrees Fahrenheit | | Warranty Description | 24 Month / Unlimited Mile Limited Warranty on parts sold on or after 04/01/18.

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. ## Frequently Bought Together - General Motors GM Genuine Parts AFS105 Heated Oxygen Sensor - ACDelco AFS106 GM Original Equipment Heated Oxygen Sensor - GM Genuine Parts AFS106 Heated Oxygen Sensor, 1 Count ( Pack of 1) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.fr/products/3922821-afs105-19178918-heated-oxygen-sensor](https://www.desertcart.fr/products/3922821-afs105-19178918-heated-oxygen-sensor) --- *Product available on Desertcart France* *Store origin: FR* *Last updated: 2026-04-24*
