How do you test the DME Temp senor to see if it needs to be replaced?

 

You can check the resistance (around a few hundred Ohms), or the voltage drop when connected (under/around 1 Volt). Both should change smoothly when heated.
The engine will stall when the sensor gets disconnected.
What exactly are you after?

 

Please don't say you replaced the head gasket for nothing.

 

I'm not saying anything....it was a good learning experience.

 

I want to know if the sensor is bad.

 

I tested mine with help from Clark's website. I removed it from the car and heated it in a pan of water. The resistance should be 3.3k ohms at 59F and 280-360 ohms at 176F.

http://www.clarks-garage.com/ Look under Sensors and guages in the Garage Shop Manual.

 

You might start with a quick resistance measurement right at the DME connector (pin numbers, anyone?).

 

Actually would be easier to do right now, as the intake is off the engine, and i have great access to the sensor.

 

It's cheap enough that I would replace it just as a matter of course. If you were having a problem with it running poorly. I think I paid about $30 for it. You can test it if you want.

 

Did you get it from the dealer or an online vendor?

 

Haven't got it yet. But I think I am going to replace it as a matter of course. THe one in there has been in for 7 years.

 

Anyone have the part number for the temp sensor? I ordered one through the dealer, but want to make sure they are getting the right part.

 

Try these Borg/Warner numbers WT5000 or WT3063. One of those will be for the gauge the other will be the DME temp sender.

I got a replacement at Advance Auto Parts of all places. 18.00 we'll see what happens after I get the car back together.
