Just replaced the passengers cylinder head, have everything back together, in all the pictures I took, I cannot find where this 3 prong Pink Plug / connector goes. Been looking for an hour. Bet it’s right in front of my face. Any ideas or pointers? This picture is on the drivers side.

It looks like the connection for the knock sensor. One is brown the other green. The green one has like an extension segment that plugs into the knock sensor pig tail and then up to the bundle of connections on the firewall right behind the cylinder head.

All three of them or connected there. This one reaches pretty easy as far as the coolant plug, but that’s not it. There are bends in the wire but it makes no sense where it goes.

Looks like it’s coming from under the throttle body, at least that’s is where I loose it while tracing. Since I had it all ripped apart, it could go somewhere on the other side too.

F-ME! Passengers cam sensor.

duh. Your right! I had it confused with the knock sensor. I had part of it right. It is the extension wire that runs the length of the engine to the cam sensor.

Ya, I wasn’t to that part of the motor yet to realize that’s what it was. Backyard mechanic lesson of the day.

How about this one? Know it’s the high temp sensor, but can’t find where it goes, it’s the last one and I can bleed the coolant. Any quick answers?

That is your ambient air temperature sensor. It snaps into the plastic piece that is at the loop end of the power steering cooler line. Located in the lower front of the radiator.

Ok, I’ll have to find a pic, it does look like it connects into something else. I am also getting a P0118 “engine coolant temp circuit high input” so I assumed it was that. Guess I have to find that now.
