Default What is the P.E.D. Connector for on my L67? (New Pics)

I was changing the back valve cover gasket, and I noticed that there was a connector dangling. I looked at it and the head of the connector was broken off like this...

The connector says P.E.D. on one side and has a number 6 on the other side. I have not turned the car over to see if it acts differently, first I would like to know what this connector regulates. Any info on it would be greatly appreciated, Thanks!

I don't think it is, all the connectors to my injectors are counted for. I thought that too when I saw it dangling to the head of the other connector it was supposed to be connected to.

So, you know where it is supposed to connect? If so, a picture of that would be more helpful.

Sorry for the dirty engine bay. I did not have a chance to clean it after getting oil all over it after changing the gasket. Do these pics help?

That is the coolant sensor. Should replace it ASAP.

Since the connector head is broken off, how would I be able to replace it? Can I strip and extend the wires somehow?

Yeah, that will be a coolant temp sensor. There will be one underneath the TB, as well. One is for the PCM, and one for the gauge, I believe. If your gauge reads normal, your PCM is flying a little blind. Get a new one. Be prepared for a little coolant to come out. And put some sealant on the threads so it won't leak.

You will need a new sensor. I don't think those are real expensive. They are very simple components.

Is it a module? When I felt it it kinda felt like the wire was coming from the lim metal area not from a sensor???
