Oxygen Sensor Installation questions. C43 W202
As some of you know I am going to replace all 4 sensors. I ordered Bosch ones that just plug in.

All four sensors are basically identical but all have a different length of connector wire on them.

My question is which sensor replaces which one? Should i just remove all of them and compare wire lenghts with the replacements?

Also is there a diagram that lets me know where they are all located? I know Speed43 said it wasn't hard at all. I know 2 are at the engine and other two are before cat and after.

Thanks everyone. She's just about ready to purr here...

Get under the car and you will see them all. Pretty easy to understand once you do.
