Nja motsåndet varierar ju med värmen
0C-- about 6000 ohms within a range of +/- 10%
20C -- about 2300 ohms
40C -- about 1300 ohms
60C -- about 600 ohms
80C -- about 300 ohms
100C -- about 190 ohms
Den mest exakta mätningen får du väll i en kastrull med vatten på spisen tillsammans med en termometer som du litar på.
Annars så kan du ju mäta strömen iställe med givaren sittandes i motorn
Sitat från ovansående länk:
"With the control unit connected, connect a voltmeter across LH ECU terminals 13 and 5 (ground). This unit is in the passenger side footwell, under the plastic cover. Remove the cover of the large electrical connector to access the backs of the pins for the test. Turn the ignition switch ON.
20C the voltage should be 2.0 +/-.5v volts.
40C the voltage should be 1.2 +/- .3volts
80C the voltage should be .5 +/- .2volts.
(Så med varm motor ska det inte vara över 0,5 Volt)

"This sensor is at the rear of the head and requires a mirror taped to the firewall and a 19mm "open-end" wrench for removal (drain the antifreeze and remove the heater hoses first). Work from the top of the engine, standing on a stepstool and using a pillow on which to kneel. It has a 2-pin D-type connector mounted right on the brass housing. The large size of the connector keeps you from being able to get a good "box-end" wrench on it, but mine was not very tight anyhow (just very hard to get to). [Tom Irwin] Those rear ECT's are a pain in the ass."
