subaru girl Posted January 23, 2006 Share Posted January 23, 2006 i have 2 that are out of the car. is their any way to test them to see if they work. Quote Link to comment Share on other sites More sharing options...
NoahDL88 Posted January 23, 2006 Share Posted January 23, 2006 What year, as the resistance will be different depending on model. For an Ea-82 the resistance should be... 14F 7-11.5 k Ohms 68F 2-3 K ohms 122F 700-1000 Ohms Basically, the hotter it gets, the less the resistance should be.

NoahDL88 Posted January 23, 2006 Share Posted January 23, 2006 Ok, those specs will be way off then, i'll look around the garage to see if i can find my legacy FSM's Quote Link to comment Share on other sites More sharing options...

I think I may have a minor problem that the cold temp sensor may be the issue. Thanks. Quote Link to comment Share on other sites More sharing options...
TheBrian Posted January 23, 2006 Share Posted January 23, 2006 Like Noah said, you have to heat up the coolant temperature sensor while measuring the resistance across its terminals with a multimeter. I'd recommend you throw the sensor in the freezer, measure the resistance, then move it to a pot of water on the stove. I don't have the specs on your engine's coolant temperature sensor, but as long as the resistance varies with temperature, it's probably still good.

Don't have for the OBW, but those specs should be very close Its the same basic sensor, as the temp increases the resistance should go down. 32F approx 3Kohm 68F 2.5 K ohm 176F 1.25-1.5 K ohm Quote Link to comment Share on other sites More sharing options...
Legacy777 Posted January 23, 2006 Share Posted January 23, 2006 If you have any question that they're not working properly, just buy a new one. They're $20 from www.subarugenuineparts.com It's a critical sensor that can cause you lots of issues if it's being tempermental. Quote Link to comment Share on other sites More sharing options...
avk Posted January 24, 2006 Share Posted January 24, 2006 That's right, the failure mode of those sensors can be intermittent. If there's a trouble code, replace. Cam, temp. and knock sensors that I replaced all showed a correct resistance reading. Quote Link to comment Share on other sites More sharing options...
