Your Cadillac Eldorado oxygen sensor may remain largely unnoticed by you, but it serves an important function in your engine. As you may be aware, your engine relies on a mixture of oxygen and fuel to create power. The purpose of your oxygen sensor is to measure the amount of oxygen in the exhaust leaving your cylinders.

The Eldorado oxygen sensor is part of a network of sensors, but it is the only one located near your exhaust manifold, where it is able to obtain the most precise measurements. A properly working oxygen sensor will send measurements to your vehicle's onboard computer hundreds of times per minute.

Without the data from your Cadillac Eldorado oxygen sensor, your car has to rely on estimated measurements. As a result, it will err on the side of caution and inject too much fuel rather than too little. This means a faulty oxygen sensor wastes gas. Other consequences of a bad Eldorado oxygen sensor include a hot running engine and black exhaust smoke. Over time, the excess fuel traveling through your exhaust system as a result of your faulty oxygen sensor can also damage your catalytic converter. It can be hard to detect a failing Cadillac Eldorado oxygen sensor; most often, it is discovered during an emissions test.
