Two days after we got the 94 E320 wagon back from the body shop (deer jumped in front of the car at 50mph) the check engine light came on. I pulled code 2 (oxygen sensor). I erased the code and it has not come back. Should I look for any detailed codes? Car still runs fine. But considering the car has 120 k miles, I already had a spare O2 sensor. My manuals say the connector plug is under the carpet. I tried to pull up the carpet on the driver's side, but am afraid I will do damage if I continue. I would appreciate more detailed instructions. tia.
