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...
