Question Which is bank one?

99 C280 Sport throwing the following trouble codes:

P0141 02 sensor heater circuit malfuncion bank one sensor one

and

P0136 02 sensor bank one sensor two


My understanding is that sensor 1 is before the cat and sensor two is behind (aft) of the cat. But, which side of the exahust is bank one?

I need to buy the correct parts and most sites call them left or right.

Hey, Boschk.
In most places in the world that is also known as the driver's side, in the UK it would be the passenger's side, and in the Middle East I suppose it could be referred to as the Left Bank.
In a more specific sense it is the bank that includes the No. 1 cylinder, so for those sites that would be the left sensors you need. And if you are close to or over 100,000 miles you may as well get the right side 'bank two' sensors while you are at it as they won't be far behind.
Take care and enjoy the ride,
Greg

I have "bank one sensor one" code on 2 of my cars. For the SL500, it is on the passenger side; for the LS430 (lexus), it is on the driver side. If you don't get a definite answer, I would say go for the passenger side as my first guess. All this is for the US spec cars.

I figured it out. It is the passenger side. I got this image from an indepedant MBZ, Porsche & BMW mechanic. I called a few dealers and got different answers, some frankly just guessed.

Hey, Boschk. You have my most sincere apologies, that is the worst advice I have given on any forum ever...and it was based upon what an indie told me a while back. (I could try to be more wrong, but I would not be successful.) I had been talking to him thinking I might take my car there for some things I can't as a practical matter do, but that is sure to be a 'no' now.
Anyway, just wanted to say I am truly sorry about that.
Good luck and Happy Thanksgiving,
Greg

No worries. I'm sure you've given more more good info than bad. Nobody is 100%.
