I asked the location of this sensor before. Car is '97 E320 (straight six). I know there is a single wire sensor in the thermostat housing. I'm assuming that is the one for the guage. I'm looking for the one read by the engine maqnagement system.
Somebody responded that it was on the rear of the block. I can't locate it from the top. Do you have to go at it from underneath? How many wires are connected to it and do you know their colors/functions? Thanks.
