Congrats my friend, It really is great news to hear that you got it working and that she purrs like a kitten now. Wish we could have stumbled on to it earlier so that we could have saved you the frustration. Ive been looking around as well for the second ECT sensor, it has to be in the back of the motor if its moved. Im not to sure tho.

God speed and great job.

I've got a 98 1500 Pickup with the 5.2. I've searched extensively for this and come up dry. There are some mentions of there being TWO Engine Coolant Temperature sensors, but I can't verify that through the shop manual. I was told by a local shop that the truck was throwing the code for that, and it's running terribly, dying all the time in a similar fashion to what I've seen posted on here a number of times.

I replaced the sensor (twice), and can't get the check engine light to go off, or the truck to get back to running properly. It's driving me insane, and I'm planning on trying an IAC Valve replacement on Tuesday, but I'm concerned that the check engine light didn't go off after the ECT replacement, so I'm wondering if there is, in fact, another one somewhere. Rock Auto lists an Engine Coolant Temperature Sensor as well as a SENDER, with different part numbers, but the photos of the units appear nearly identical.

Any help would be greatly appreciated, and thanks for having such a tremendous site.
Did u unhook the battery b4 doing the sensor? If not then unhook it for 5 to 10 min. Then hook it back up. It should be off, as long as the problem is fixed it won't come back on. If it's not fixed it will come back on eventually.
