OEM GM Oxygen Sensors

The oxygen sensor in your vehicle measures the amount of oxygen in your exhaust gas in order to determine the amount of air needed for the fuel injectors, which gives you optimal performance and fewer emissions.

This sensor helps determine the air to fuel ratio by reading the exhaust, and in turn, it sends the mixture information to the central computer, which then makes adjustments in order to make the mixture richer or leaner. An incorrect mixture in your vehicle will cause it to sputter or run rough. Whether you drive a Silverado 2500Enclave, or other GM vehicle, there is a preferred mixture for your engine.

Replacing the oxygen sensor with a genuine OEM GM part will mean that the mixture is going to be right for your vehicle and that the sensor is going to be a durable replacement part. Unlike generic sensors, the GM sensor will fit correctly and is manufactured specifically for your vehicle.

The oxygen sensor is not a regular maintenance part, but it does go out at some point in most vehicles. It is located in the exhaust, so it is subject to some intense heat, and since it is a sensor, it is sensitive. You will probably need to replace this part at some point in the ownership of your vehicle.
