Sure do. the bank 1 sensor 1 oxygen sensor is located in the exhaust pipe on the same side as the number 1 cylinder. So if the number 1 cylinder is on the driver's side, then the bank 1 sensor will be the forward most oxygen sensor on the drivers side, then next one in line will be the bank 1 sensor 2. Obviously, the other side will be bank 2, sensor 1 and bank 2 sensor 2.....good luck!

if u have one oxygen sensor then u need to take a deep look at the bottom of ur car it will be somewhere at the Exhaust pipe if u have a catalytic converter then u will have two oxygen sensors one before the catalytic converter & the other will be after the catalytic converter. Note: the catalytic converter is located at after a little bit of beginning in Exhaust pipe.

bank one in a C280 99 sport its located on passanger side where 1st cylinder its located, When you step front of you car, take out the plastic cover and see right on top of the front spark plugs, you will see numer 1 on you left side (diver side) 1st top of 1st spark plug you'll see number 4 on you right side same first spark plug from your right.
In you want to replace bank 1 1-2 or 1bank-2nd sensor. you'll need to remove exhaust pipes about 6 bolts total in you garage your car well lifted and a 12pack of beer one friend of you may take about 3 hrs be patiente.. beers are for after job done!!
