Oxygen Sensor for Chevrolet Cavalier
Making sure your car has a sufficient oxygen supply is the job of your Chevrolet Cavalier oxygen sensor. You will find this sensor mounted near your exhaust manifold, where it has the strenuous task of monitoring the oxygen levels in the red-hot exhaust leaving your cylinders and sending this data to your vehicle’s onboard computer hundreds of times per minute. Your vehicle uses the information it receives from the Cavalier oxygen sensor to determine the amount of fuel that should be injected into your combustion cylinders.
The precise measurements your oxygen sensor takes helps your engine strive for an optimal oxygen to fuel ratio of 14.7 to 1. Unfortunately, your Chevrolet Cavalier oxygen sensor is the only sensor located in the direct path of your exhaust, so when it is not working right, your car has to guess at the oxygen content.
In most cases this results in too much fuel being injected into your cylinders, since too little fuel can damage your engine. There are many reasons why your Cavalier oxygen sensor may fail. If the sensor becomes contaminated with fuel additives, engine oil, gasket sealant, or antifreeze, it may not be able to perform. Additionally, your oxygen sensor will wear out over time through normal use. It can be difficult to detect a faulty Chevrolet Cavalier oxygen sensor, since it will sometimes work intermittently and a diagnostics test may not always identify a problem. You should plan to replace your Cavalier oxygen sensor whenever you have exhaust work done.You’ll find a full line of replacement oxygen sensors in our extensive online catalogue, so you can restore your fuel economy and engine performance.
