3.0 temp sending gauge unit, where is it? Their are three sensors in the back drivers side. Which one runs the gague? Thanks

 

uuug this shouldnt have been moved!

Agreed and which one is the ECT sensor? The TFSM sucks ass in this one regard...

 

bryon its the one closest to the drivers side, just has one metal prong on top

 

It is a 2 wire guage in the center of the engine between the plenum and the firewall. It unplugs and I think its a 22mm deep socket you need to remove it.

 

Thanks for all of your help I found it, and it checked bad. Hopefully this will fix my gague. thanks agian

 

Not to confuse things but I just went through this last week. The Coolant Temp Sensor is the small one with the gray 2 prong connector directly behind and below the throttle body. It took a 19 MM socket to remove it I believe. The BIG one that looks the same only bigger directly in the middle area of the Intake took a 22 MM socket to remove, but the part did cross with what I was given at the parts store. I cross-referenced the part number on the side of the sensor and it turned out to be the Cold Start Injector sensor (Black Connector). I just want to make sure that we are both on the same thing. After I changed the "little gray one" my temp needle stopped bouncing all over the place, but my problem was intermittent anyway so I cannot be 100% sure until I drive it for a good while. If I am wrong, please let me know, if not then I hope that I helped out a little.
