Getting a check engine light for your downstream O2 sensor?

This is a direct-fit replacement sensor designed for your car.

It's a downstream sensor (that's the one after the catalytic converter), so make sure that's the one you need – don't mix it up with the upstream sensor!

It has a 4-pin male connector for a plug-and-play installation (no splicing wires if your connector is good).

This sensor is built to meet OEM specs and is designed to fit specific vehicles: the 2009-2011 Chevrolet Aveo and Aveo5 (with the 1.6L LXV engine, VIN E), and the 2009-2010 Pontiac G3 (sedan and hatchback, also with the 1.6L LXV engine, VIN E).

The reference numbers for this part are 250-24850 and 350-34321.

A failing downstream O2 sensor can affect fuel economy and cause your car to fail an emissions test.

Replacing it with a quality part can help get everything running smoothly again and turn off that pesky light.

We're so confident you'll get a good fit and function that we back it with a 1-year unlimited-mileage quality guarantee.

Just make sure your vehicle details match before clicking buy!
