Correct Temperature Sensors for w124
Its for an 1988 300TE
My mechanic stated I was getting an error code for Coolant Temperature Sensor and Altitude Temperature Sensor I am assuming the coolant temp sensor is the water temperature sensor right? If so, which one is the correct sensor? http://catalog.worldpac.com/mercedesshop/sophio/wizard.jsp?partner=mercedesshop&clientid=catalog.mercedesshop&baseurl=http://catalog.peachparts.com/&cookieid=2C7020XP82C70216EZ&year=1988&make=MB&model=300-TE-001&category=C&part=Water+Temp.+Sensor&appEngines=_any --- Any sites have the Altitude sensor? Fastlane doesn't seem to have any. Much appreciated. Thanks! Ps2cho,

There were several production changes for sensors. You need the engine serial # and then just go see where you fit on the parts eng # designation next to the part you posted..
We can't tell you which one w/o that info..............they tell you right there

Ok thanks!
I just filled my 300TE up and 100% city driving net me 12.5mpg Thats horrible isn't it? The car wasn't idling and I was driving gently. I suspect if I were driving a little harder I would have been at like 11!!! Do you have any thoughts that my Thermostat could be at fault? I have no engine temperature problems but I heard somewhere this effects MPG if its bad. Any thoughts?

The temp sensor in question is an input for controling a/f mixtures. If it is off/broken/out of calibration, the fuel management thinks the car is not up to temp and runs the a/f on the rich side...so, that is why your mechanic said you need a sensor..and why you get crap milage
The temp that you see on the guage is a different sensor altogether and only reports coolant temp back to that gauge. If that gauge is reading correctly, you do not have a thermostat problem... http://catalog.worldpac.com/mercedesshop/sophio/wizard.jsp?partner=mercedesshop&clientid=catalog.mercedesshop&baseurl=http://catalog.peachparts.com/&cookieid=2AO123CS42C70U3Y8C&year=1988&make=MB&model=300-TE-001&category=P&part=Water+Temperature+Sender You can see that your car had CIS sensor changes , so, as previously posted, you have to have the engine # to find which sensor your engines system is designed to use...

I can't seem to find the engine serial # anywhere....Where is it located? I did searches online and all I found was "left side of engine block" but I looked as good as I could and found no numbers.

Doesn't have either for the two numbers
Engine: 10-016764- Engine: 12-082792- ^Those are the two engine's listed on Fastlane.

They are not your EXACT engine number . b/c they are serial numbers . If your engines serial is BEFORE that#, that is the part they want you to use ..If it is After, then that is the part you use. Your engine is a 103.983, with a serial # following that. It is the serial# they want and it is the serial # that determines where your car came in the production run and therefore which production changed sensor that engine requires. That is what the " - " signifies. That means "up to and including serial xxxxx" or "including and after serial xxxxx" And the 10 or 12 means the car is a Manual trans or an Auto trans..so you use that to narrow yours down. 10 is man , 12 is auto. Rather than listing the FastLane #s, why don't you just list YOUR serial # and someone here will be happy to tell you which sensor fits YOUR chassis by simply using the FastLane info................

Thanks! Hopefully this will fix my MPG, and maybe (although I doubt) the misfire. Will report back in a few days with the results. Much appreciated bearing with my "noobyness" Arthur. I have zero experience with cars so I am learning very fast!! I have no help outside of these forums so its all me learning. I really do appreciate it.

But there is still a serial # range for the auto ones [ 12], so you still have to use the serial # to determine the correct part. Do you see the question they ask you when you go to look up the part?? http://catalog.worldpac.com/mercedesshop/sophio/wizard.jsp?partner=mercedesshop&clientid=catalog.mercedesshop&baseurl=http://catalog.peachparts.com/&cookieid=2AO123CS42CA0T61CZ&year=1988&make=MB&model=300-TE-001&category=C&part=Water+Temp.+Sensor If you still find this confusing, then you may just want to call Phil @ FastLane and give him the chassis/yr/engine # and he will surely send you the correct part.
