## Overview

The GM Genuine Parts AFS98 Heated Oxygen Sensor is a high-quality, OE-spec sensor engineered to measure oxygen levels in exhaust gases, enabling your vehicle’s ECM to optimize fuel efficiency and emissions.

## 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).

## Questions & Answers

**Q: What are the symptoms of a bad O2 sensor?**
A: A failing or failed O2 sensor may not detect the engine’s air-fuel ratio running too rich or too lean. Common signs include an illuminated check engine light, poor fuel economy, rough idling or failed emissions testing.

**Q: Can a bad O2 sensor cause the check engine light to come on?**
A: Yes. When incorrect oxygen levels are detected in the exhaust, the sensor will trigger the sensor to send a fault code and turn on the check engine light.

**Q: Will replacing an O2 sensor improve gas mileage?**
A: A properly functioning O2 sensor can help the vehicle maintain the optimal air-fuel ratio for combustion, helping balance fuel economy, engine performance and emissions.

**Q: How long do O2 sensors last?**
A: O2 sensors can last between 60,000 and 100,000 miles. However, O2 sensor longevity depends on numerous factors including heat, carbon buildup and normal wear.

**Q: Why choose GM Genuine Parts O2 sensors instead of aftermarket brands?**
A: GM Genuine Parts O2 sensors are engineered to original equipment specifications for precise fit, form and function. They are designed to integrate seamlessly with your vehicle’s engine.
