Poor idle or erratic jerking at steady throttle are just a few problems it may cause. The last but not the least thing is high fuel consumption — that’s why we having a finely made oxygen sensor is so important.
The oxygen sensor is must-have for any vehicle — the part is mounted in the exhaust manifold to check how much unburned oxygen exits your vehicle’s engine. It’s one of the best way to gauge the fuel mixture. It all ends in your four-wheel friend’s computer so it knows should it burn less or more oxygen.
Can you drive a vehicle with bad oxygen sensor? Well, technically yes. Automotive OS would be displaying different calculations, however, driving with poorly functioning auto part is like avoiding dentist, especially when oxygen sensor is not the least piece in your vehicle.
If there’s a light on the engine or you see bad gas mileage as well as rotten egg smell, it’s likely that your oxygen sensor went bad. Thanks to the cost of aftermarket parts, they won’t break the bank and due to the Web you can choose and order the needed oxygen sensor in a few clicks.
We have gathered and tested automotive oxygen sensors which truly worth your attention. Go through our review to find out about editor’s choice and other decent devices.
Things to Consider
Materials. Even though oxygen sensor is not a big part, it’s one of the primary parts in a vehicle. Make sure that a device you are about to purchase was made of durable and dependable materials since you don’t want to change oxygen sensor each year.
Installation. The easiness of installation matters as well if you don’t want to spend hundred of bucks for it. The vast majority of oxygen sensor kits have detailed instruction and explain from A to Z how to replace worn-out part for a new one. However, even if you get lost in it, you may always hire someone who’ll do that for you since oxygen sensor replacement is not a rare service at all.
Brand. Sometimes it matters — if you found an oxygen sensor that has been produced in the USA or stands for a famous brand, pay attention to it. It’s not the primary factor when selecting an oxygen sensor, however a decent brand oftenly means dependable materials and good functionality. Pay attention to Bosch and ACDelco oxygen sensors in our review down below.
Measurement. Even though an oxygen sensor seems to be not a big deal, we insist you need to check all details before purchase. Sometimes even one wire that does not fit your vehicle may cause additional money spending. If you want to avoid that and don’t want to waste your time — check twice all specifications on oxygen sensor you’re getting and of the car you currently own.
Vehicle economy. Many auto enthusiasts seek for instant fuel economy once they have replaced oxygen sensors. You need to ride at least a hundred miles to check difference in your auto economy as well as compare your car performance.
Mileage. If you still have doubts to replace or not to replace, here’s the thing — it’s recommended to replace oxygen sensors every 80,000 km.
Look. There are some oxygen sensors which look different, however, you should not worry. The first thing you have to do is to check connector plug, cable length and other detailed listed in kit. If there’s a whole package, there should not be any problems with installation and use.
Number of sensors. Depending on a model and production year, your vehicle may have one or two oxygen sensors. Check your auto’s engine, year and make in order to find out about it.
Assembly. There are brands (as Denso in our review) that openly claim they do not produce every single piece of oxygen sensors by themselves. If you are interested in durable O2 device that will deliver excellent performance to your four-wheel friend for many years, pick brand that claims its assembly and ensures device’s quality.
To find out about oxygen sensors type, let’s go deeper to the definition. A sensor is a device that provides output in order to detect the changes in quantities. This device produces electrical signal and corresponds about all inputs.
Nowadays we got used to use many different types of sensors — not only for vehicles, but for different electronics appliances as well.
There are two types of oxygen sensors: narrow band and wide band.
Speaking about the first one, it rolled out to the market in the mid-1970s. In those years only two automotive brands used them: Saab and Volvo, but in 1980 those sensors came to American market.
Narrow band sensors are the most popular and they are known as ‘oxygen sensors’. This is because of dozens years it has been the one and only type of sensors. They are named so because a device can detent a narrow band of air fuel ratio. Usually it has on/off switch, however, it does not provide information how lean or how rich the mix is.
As for wide band type, they are more precise, but at the same time they are pretty rare at the market. Before purchasing you need to check your vehicle’s make, year and model in order to make sure you’re getting an oxygen sensor that will find your vehicle.
In this review we’re talking mostly about narrow band oxygen sensors as we tested them out.
