P0115 Engine Coolant Temperature Sensor

Hey everyone,

I looked on here (and all over the rest of the interwebs) and am having trouble finding the location for the ECT that trips this code. I need the back one, not the front 4-wire one.

I've got a 2000 V6 prerunner, California emissions, if that matters.

That best I can find is this video (https://www.youtube.com/watch?v=ESsI8N0wHpI in spanish, and blurry) that sort of shows where both ECT sensors are. The bigger of the two sensors shown in this video I have already replaced, and CEL still fires.

The smaller, single wire one is near the firewall, but I could not see where, even practically laying on my engine.

Anyone have a diagram photo or good explanation?

 

no one?
