[make mine an aston]

Hi
I own a 1997 520 m52 with it seems an OBD1 socket, does anyone know how many oxygen sensors it should have?
My understanding is that OBD1 equipped cars only have one sensor, down stream of the cat', but some suppliers are advertising front and rear sensors for my car:conf
Any one got any ideas?
thanks

Good luck and welcome to the Werkz

Thanks for the links Brettski, it now seems like i have 3 sensors, one for each 3 branches of the manifold and one downstream of the cat!
Guess i'll have to get the bonnet (hood) up and see if i can see them.
