Cadillac STS Oxygen Sensor

You enjoy taking care of your STS.

Select Your VehicleAuto enthusiasts appreciate the luxury built into each Cadillac, and understand that only top quality repair STS parts will suffice when your car or truck needs fixing. When your Cadillac STS left the factory, it was destined for a person with discerning taste who wants unique styling in their automobile. Make no mistake, you didn't buy your STS unless you wanted to buy long-lasting quality and a trusted brand both rolled up into one car, truck, or SUV. Anyone who owns a Cadillac knows that when it comes to maintaining their vehicle only the most superior replacement parts will do.

What Oxygen Sensor does for your vehicle.

Reducing harmful emissions that come from your car or truck depends on the quality and performance of the parts you use. The fuel-injection system on your Cadillac STS is runs on signals sent by your ECU which uses data collected by your oxygen sensors. Your Cadillac STS oxygen sensors sit in the exhaust manifold, exhaust pipes, and catalytic converter and analyze the quality of the exhaust gases to determine how well your fuel delivery and emissions reduction parts are working. When oxygen sensors fail your engine will not be operating as it should; lacking in power and lowering gas mileage, and emissions from your tailpipe may be in excess of legal levels.

What CPD has to make it special.
