Ohm's range from the temp chart in the /Engine Manual-Combustion Manual-07.3 Mechanical/electronic gasoline injection system (KE injection)-121 Testing electrical components of KE injection system. page 60
Temperature °C........Resistance kΩ -20........................15.7 -10.........................9.2 0............................5.9 10...........................3.7 20...........................2.5 30...........................1.7 40...........................1.18 50...........................0.84 60...........................0.60 70...........................0.435 80...........................0.325 90...........................0.247 Same resistance values apply to KE intake air temp sensor. I think this chart applies to these 2 sensors for all KE systems but don't know for sure. Is yours 2 prong? http://catalog.eautopartscatalog.com/mercedesshop/sophio/wizard.jsp?partner=mercedesshop&clientid=catalog.mercedesshop&baseurl=http://catalog.peachparts.com/&cookieid=1FX0MB1RS1IG0SWQP6&year=1986&make=MB&model=300-E-002&category=C&part=Water+Temp.+Sensor&appEngines=_any Just un plug it and measure the resistance across the 2 prongs, compare to engine temperature...
