Shop Mercedes C230 Replacement Oxygen Sensor

Mercedes is trusted for engineering performance cars that offer durability and smooth handling. For generations vehicle buyers have opted for the reliable engineering of Mercedes and valued the elegance delivered by this manufacturer. Would it make sense to fork over a big check on a great, stylish luxury car, and then skimp on new parts? To preserve the comfort and luxury you made an investment in with your Mercedes C230, it's critical to buy only the most reliable brand name OEM parts. Luxurious sedans including your well-appointed Mercedes C230 are manufactured to be used gently and also given proper repairs. The Mercedes in your carport was put together with the highest care and expertise; it needs new OEM parts of a similar high level of reliability. A Mercedes C230 Oxygen Sensor is a component of your emissions control system and helps with changes in the air to fuel ratio, removing the necessity for constant altitude adjustments. A high quality Mercedes C230 Oxygen Sensor continually tracks how much oxygen which is funneled into your car or truck's cylinders. Whenever the air-fuel ratio is not adequate, inadequate combustion will be the consequence; in addition, a too-rich air to fuel ratio leads to excessive wear to your motor and excessive unburned fuel from your vehicle's tailpipe. Your car or truck has a place in your heart because of its excellent performance and awesome style, so to have it running in top form you want the best in quality parts and accessories. First-rate engine power and automotive performance are supported by top-notch components and accessories. A great way to safeguard any vehicle's performance is by using our quality parts and incredible customer service. Caring for a vehicle with OEM quality parts is the best strategy, time after time. If there are any concerns about our parts or accessories, our customer support specialists can be reached during business hours - with our standard first-rate customer service!

Research on Oxygen Sensor for Mercedes C230

What does my Mercedes C230 oxygen sensor do?

No one wants to spend their extra money at the gas station. No one wants to intentionally pollute the air they breathe, either. Your Mercedes C230 oxygen sensor keeps you from doing these things every time you drive.

A Mercedes C230 oxygen sensor takes constant measurements of your sports coupe's exhaust gases. It sends the information back to your car's ECU, or engine control unit. This allows it to finely tailor the mix of gas and air being sent to your engine for all kinds of conditions - whether you are driving in extreme temperatures or when you are driving at high altitudes. This sensor is the one that makes sure your catalytic converter is able to do its job properly.

How can I tell if my Mercedes C230 oxygen sensor is failing?

Hopefully you have been using good quality fuel and have been changing the air filters on a regular basis. This keeps your Mercedes C230 oxygen sensors from being caked with residues and gunk before their time. Eventually, though, they will have to be replaced.

A bad Mercedes C230 oxygen sensor will show signs that it needs to be replaced in several different ways. One early indicator might be a failed emission test. Your car will emit CO outside of the acceptable range if this part fails. It is estimated that a bad oxygen sensor is the reason for 50-60% of vehicles that don't pass a mandated emissions test.

Another possible first symptom of a problem is the most general one - your dashboard's "check engine" light will come on. This light's only purpose is to indicate that one of your car's sensors is not functioning properly. If that light comes on, and you have been noticing problems like rough idling, misfires (an unmistakable jerking when one or more of your engine cylinders fires at the wrong time, with an accompanying loss of engine power), or irregular idling, it's possible that your Mercedes C230 oxygen sensor is causing your problems.

You may also notice that you are filling up the tank more often. A bad Mercedes C230 oxygen sensor will not make the adjustments necessary for your car to get a proper air to fuel ratio. Too much gas will be injected into your engine. (If you suspect this is happening, take a moment to write down how much and how often you have to fill up. If your mileage seems to be going down noticeably, a failing Mercedes C230 oxygen sensor may be why.)

If your car is a l996 or newer model, and you have access to a OBD-II code checker, you can tell which Mercedes C230 oxygen sensor is failing based on the diagnostic trouble code.

How much does it cost to fix my Mercedes C230 oxygen sensor?

Assuming that you don't also have a failing catalytic converter, a Mercedes C230 oxygen sensor replacement will cost anywhere from $200 to $400 at your local dealership or independent repair shop. It is not uncommon for them to recommend that you replace all four of them at once, since the other three may still set off your "check engine" light. Your final price may be rather steep.

However, if getting a little dirty scares you less than that estimate, you could save some serious money getting the parts you want right now at PartsGeek.

Ordered this part from PartsGeek after ordering a similar Bosch product on a different auto parts website, which I had to return at the urging of my mechanic (The Bosch universal upstream + downstream o2 sensor, my mechanic said the actual connector design was bad and would probably fail sooner). PartsGeek was the cheapest for this OEM replacement part, by at least $10-15 compared to other parts websites. My package arrived very qyickly! - Quick OEM Replacement
