85 cutlass with the 231 3.8 v6. I am getting a code 15, I turn the car on and after about 5 minutes the check engine light comes on. I've replaced the temperature switch but I'm lost on the temperature sensor. My car has what I'm assuming is the sensor located on the front center of the engine. It doesn't look like the 2 pin sensor it has a white plastic nipple but there isn't a plug on it. I've searched everywhere for something that looks like would plug into it but I see nothing. Auto parts and internet keep showing me the black 2 pin sensor. Anybody have pics of there sensor and plug or can I make the 2 pin sensor work?
