Unhappy Code #2 on a 94 E320 Wagon


I need some advice. My check engine light came on yesterday. I read the codes and code #2 came up, which is the o2 sensor?? is this true? If it is, my questions are:

- can i do it myself?? I'm pretty new to my MB since I got it a month ago, and I have no car experience but I'm willing to work on it as long as i have some documentation/advice.

- should I buy the OEM part? or should I go with the Universal part?

- where is the o2 sensor in my car?

Thanks a lot in advance!

Do a search on here on W124 codes. Get to know Arthur Dalton. These cars are straight forward as being able to read all the codes. You are just scratching the surface in regards to what an individual can do with a home made reader.

I think code 2 is the coolant temperature sensor.
