Hyundai Oxygen Sensor Replacement Cost

As a Hyundai model owner, you will eventually need to take control of maintenance and long-term repairs, with oxygen sensor replacement and costs being one thing to keep in mind. When it comes to the Hyundai oxygen sensor replacement cost and process, this can be tricky for someone who doesn't know where to begin. Luckily, the pros at Colonial Hyundai in New London are here to discuss price and timeline and explain when you need to replace your oxygen sensor. Stick around as we dive into this topic below!
What is the Oxygen Sensor?
The oxygen sensor of a car, truck, or SUV measures the amount of oxygen in the vehicle's exhaust system. It can then work with the engine control unit (ECU) to help the engine run efficiently. Newer cars often have two oxygen sensors, one before the catalytic converter and one after. Of course, Hyundai models might differ slightly based on make and model, but all engine-based vehicles will see an oxygen sensor or two to maintain an efficient, safe-running system.
Hyundai Oxygen Sensor Replacement Cost
An oxygen sensor replacement will normally cost between $250 and $350 for Hyundai drivers, but it can improve a car's MPG and performance, making it an investment for the future. For the actual parts, no labor included, Hyundai sells these for around $115-$225, which is worth mentioning.
Factors Influencing Replacement Costs
The factors that might impact your Hyundai oxygen sensor replacement costs are mainly attributed to labor. Depending on where you go, this can add $50-$75 or so to your final price, but this depends on the model you drive and its condition. Well-maintained Hyundais will be cheaper to work on and inside than those experiencing age or weather-related damage, which can affect your Hyundai oxygen sensor replacement cost. If you have any questions about pricing and labor, please contact Colonial Hyundai; we'll gladly assist.
Signs You Need a Hyundai Oxygen Sensor Replacement
Regarding the signs and symptoms of a bad Hyundai oxygen sensor, this can present itself in countless ways. Here are some common side effects of a bad sensor to be aware of:
- Check engine light
- Poor fuel economy
- Rotten egg smell
- Black exhaust smoke
- Rough idle
- Engine surging and hesitation
- Failed emissions tests
Again, your oxygen sensor is responsible for clean air reaching your car's engine, so without it working, you will notice smells, issues with performance and engine starting, and heightened smog/emissions.

Common Symptoms of a Failing Oxygen Sensor
For Hyundai drivers worried about a failing oxygen sensor on their model, there are quite a few 'common' failure symptoms to note. As we said, a lit check engine light, decreased fuel efficiency, rough idling, a rotten egg smell from the exhaust, black smoke, engine hesitation, poor acceleration, and failing emissions tests are tell-tale signs of this problem, only worsening as time goes on. If any of these things have started happening while you are behind the wheel, please schedule an inspection with your nearest Hyundai dealership or approved service center.
Importance of Addressing Issues Promptly
One of the most important components of a Hyundai or non-Hyundai vehicle is its engine. Every part that helps with the engine's ability to function, no matter how big or small, is extremely time-sensitive and should be addressed as such. An engine's oxygen sensor is responsible for emissions and overall efficiency, so you want to handle it ASAP when it goes bad. If your emissions become too high and smog levels outpace state standards, this can make your Hyundai illegal to drive. Therefore, the oxygen sensor is a big deal in your everyday driving experience and should be a priority.
DIY vs. Professional Replacement
If you want to try a DIY oxygen sensor replacement over a professional one, it will take time and expertise. Of course, those who are skilled in engine repair and feel comfortable with it can try this. Still, you will need an OBD reader, and you will need to purchase the right sensor directly from Hyundai. Replace both sensors if applicable, and do NOT clean it or make any alterations.
Most people prefer professional service at their local dealer, as this is backed by industry professionals. In many drivers' opinions, the $50 or so price point is worth it. Colonial Hyundai is always here to help.
Pros and Cons of DIY Replacement
The pros and cons of a DIY Hyundai oxygen sensor replacement are another factor to consider, especially if you are 100% confident in your engine repair skills. A pro would be saved costs on labor, although you still have to buy the essential repair parts and new Hyundai-approved sensor(s). Therefore, you could actually end up spending more money to get this done. You also risk damaging your engine and voiding your industry-favorite Hyundai warranty, which nobody wants to do.
These are some good points to keep in mind while making your choice.
Benefits of Professional Service
Weighing in on the benefits of a professional Hyundai oxygen sensor replacement service, you do have a few perks and securities by doing this. As we mentioned above, by scheduling with your dealer, you won't void your warranty, nor will you need to do anything but pull in and receive fast, friendly service from a certified technician. Moreover, the labor is worth it when considering what could go wrong if you attempt this on your own.
