Cut off wires connecting to throttle body

Does anyone recognize the missing wires in these pictures?






I discovered this while taking out the EGR cooler and intake manifold for cleaning. Both were clogged. Changed the PCV valve too. The ICE had been misfiring at idle and low speeds, and it was using up coolant. I’ve already tried new spark plugs, and I suspect a head gasket leak.

Anyway, what are these broken wires for? Are they related to the issue I’m having? I noticed them as soon as I had the air filter box out, so they must have been like that while I was driving it.

Car has 247,000 miles, I’ve only owned it for 6 months, this is my first time I’ve had to do any work on it, and I don’t know much about its prior history.

Thanks everyone for having such a great forum! I’ve never posted here before, but I have used the old threads extensively for repair and maintenance help on my other car, a 2006 Prius.

 

Thanks for the replies! I can repair the wire, but where is the other end of the wire supposed to go to?

 

Thanks, I’m downloading the wiring diagram now.

Any idea what would have caused the wires to break?

Also, what does the MAP sensor do? And could it be related to the misfiring?
