How Much Does An Oxygen Sensor Replacement Cost?

All modern cars are equipped with the emissions control system which includes the oxygen sensor. If the oxygen sensor fails, then your car starts to lose its efficiency, more fuel is used up, and more harmful emissions will be released. The check engine light will indicate the oxygen sensor failure. If you notice this lamp blinking, then it is a sign to replace it as soon as possible to avoid other component failures.

Oxygen Sensor Labor and Part Costs

Depending on your car, the oxygen sensor cost may vary from $20 to $100. The labor cost depends on your vehicle model and the mechanic to whom you go. A Mechanic's labor rates range from $50-$150 an hour. Usually it will not take them more than 30 minutes and will cost you less. However, in some vehicles it’s required to remove other components before the oxygen sensor can be reached, that’s why the labor time and cost might be higher.

The table below shows examples of the oxygen sensor prices for five different models of vehicles. The table also shows the location of the sensor for each car. This price is only for one oxygen sensor. If you purchase oxygen sensors as kits and sets as they recommended to replace at the same time, you will save a lot of money. All these examples are for new aftermarket sensors.

As we already mentioned, the replacement of the oxygen sensor is an easy process, that’s why you can do it by yourself and save money on the labor cost. You just need to know its location and to replace it, and the job is done!

How to Save Money on an Oxygen Sensor?

First of all, don’t rush on buying a replacement oxygen sensor from the local shop or your mechanic. Just ask for the exact manufacturer part number and with this part number search on an online catalog to find the oxygen sensor you need.

Second of all, try not to let the oxygen sensor to fail. Keep it maintained on a regular basis, check it and if you notice that its efficiency gets down, then replace it. This way, you can save on an average fuel cost per year or avoid the failure of the catalytic converter which is one of the more expensive parts to replace.
