O.2 Sensor

[owenrich]

Hi, has anyone replaced an O.2 sensor? If so are there any points to watch for and how easy is it? I have the code P0131 showing which is "O.2 sensor circuit low volts". I understand that the sensor can not be cleaned, but should be replaced. The car is a 2003 SLK200K with the M111 engine (Same as 230K). Any advice would be welcomed.

Replace the sensor with OEM quality parts. Just don't burn your hands on the hot exhaust.
