What is a Mercedes CLK320 oxygen sensor?

Your Mercedes CLK320 has an internal combustion engine. As you probably know, the sedan’s engine needs gasoline to run. What you might not know is that the engine cannot burn pure gasoline. Instead, it requires a precise mixture of gas and oxygen to create power. The Mercedes CLK320 oxygen sensor measure the amount of oxygen in the vehicle’s exhaust. The measurement indicates whether the gas and oxygen in the fuel mixture are in correct proportion. If the sensor notices that fuel is too rich or too lean, you can take steps to correct the problem and improve vehicle performance.

How much does a Mercedes CLK320 oxygen sensor cost?

At PartsGeek.com, an oxygen sensor for a Mercedes CLK320 typically costs between $60 and $130. Your CLK320’s model year, the oxygen sensor brand, and the oxygen sensor’s specifications determine the exact cost of your replacement sensor, though.

How do I know if I need to replace my Mercedes CLK320 oxygen sensor?

An illuminated check engine light is one of the clearest indicators that the Mercedes CLK320 oxygen sensor is bad. Since the light illuminates for a variety of reasons, though, you should watch for the following signs your Mercedes CLK320 oxygen sensor is bad:

  • Rough idling
  • Decreased power
  • Decreased performance
  • Worsening fuel economy
