GM Genuine Parts 213-4229 Heated Oxygen Sensor – OE Replacement (12609457)

Overview

GM Genuine Parts 213-4229 Heated Oxygen Sensor is a true OE replacement component designed for GM vehicles. It monitors oxygen levels in the exhaust, enabling the engine control module (ECM) to fine-tune the air-fuel ratio toward the target value of 14.7:1. When the system maintains this balance, you may notice steadier idle, smoother drive quality, and cleaner operating conditions under typical driving loads.

As a GM-recommended replacement part, this sensor is built to GM OE specifications for fit, form, and function. It carries the same quality, reliability, and durability you expect from genuine GM parts and is designed to withstand the heat and vibration of daily driving. The connector gender is female, ensuring compatibility with GM harnesses and factory wiring harnesses.

What it does

The sensor acts as a feedback device in the exhaust system, measuring oxygen concentration and relaying data to the ECM so the engine can refine the air-fuel mix in real time. This closed-loop control helps the engine respond to different driving conditions, from cold starts to highway cruising, with a focus on efficiency and emissions consistency.

Key benefits

• Detects oxygen content in exhaust gases to balance emissions and fuel economy.
• GM-recommended replacement part for your GM vehicle’s original factory component.
• Offers the reliability and durability associated with GM OE parts.
• Manufactured to GM OE specification for precise fit, form, and function.

Why choose GM Genuine Parts

Choosing GM OE parts supports factory-tested reliability and consistent performance across GM vehicles. This sensors is designed to withstand thermal and vibrational demands while maintaining operation across a wide range of driving conditions. It’s built to meet GM’s quality standards and is backed by GM’s parts network for support and warranty if needed.

• OEM-grade design that matches your vehicle’s original equipment.
• Backed by GM quality standards and warranty support.
• Easy installation with compatible female connector configuration.
• Fully compatible with in-vehicle diagnostics and emissions systems.

Real-world use

Consider replacing a worn sensor during routine maintenance or when symptoms like rough idle, high fuel consumption, or fluctuating exhaust readings appear. In many GM vehicles, a new O2 sensor can restore proper feedback to the ECM during everyday driving, from city commutes to highway trips, without requiring additional modifications.
