I think it is suppose to fit the coolant sensor in the front of the intake but the connector is round and the sensor I bought is not. The wires appear to be light yellow and black.

 

That should be it. Here is a picture of the same plug, yes I know it is on a tbi but it is the same on my tpi also.

 

Is that the coolant temp sensor? I have a cts and it does not fit with the connector. Is it possible is it for the mat sensor? When I got the car the sensor's plastic top was broken off. Just two little prongs sticking up with the wire attached.

 

The one circled is definately a CTS. The Mat sensor wire for a tpi does not come that far forward in the bundle. It exits the wire loom at back top of the driver side vavle cover area and then there is an intermediate wire that goes from the main harness to the MAT.

 

And FWIW, I believe the CTS and the MAT are totally interchangeable......

 

you are correct

 

Does the cts come with a round top or oblong (like circled).The connector I have is round (top picture w/arrow) Thanks

 

Notplayn, what brand of paint did you paint your T/B and tensioner in that pic.?...Looks great.

 

I went out and took two pics.

first my cts on tpi



Second pic of plug oblong

 

Brut, to answer your question I used plasti-kote engine enamel primer and then dupli-color engine enamel cast coat aluminum.

Novass, thank you for going to the trouble. Looking at you pics it hit me like a brick. The end of the sensor was still attached to the connector (cant see the forest for the trees). I am so used to fixing the connectors that I expected something wrong when there was not. Looking at the connector unpluged I knew something was wrong on my end. Thank you and everyone else for the responses. I am sure I will be posting again. My next sensor to tackle is going to be the MAT.
