Temperature Sensers
 

Can anyone tell me the name of these sensors. The guys at the auto parts think they are all same. lol
I bought one and put it on my car and it started to shake real bad I had to take it back and get a refund. Here is a pic of it.
It's a 93 Mazda 626 (LX) 4 cylinder with an automatic transmission. I number the sensors 1,2 and 3. One of the harness is black and the other is green, #2 is a single pin slide on. P.S I remove #1, so it's just an empty spot.:D
