Hi guys I joined the forum. I've desperately been trying to fix my girlfriends 1998 Toyota Corolla. (Might have 1997 engine thought not sure)
She had the check engine light come on and had the code pulled and the code that came out was the P0115. I know it's Engine Temperature Sensor Circuit. We went out and bought a new one see picture below. The problem is we tried to replace it and what we thought was the engine temperature sensor but it looks different. The one we tried to replace the connection was completely different. The one her car was Shaped like a "D" connection and the one we bought is a triangle shaped connection. Also the end that goes into the engine is different as well.
I guess my I have 2 questions.
1) Where is the Engine Temperature Sensor located exactly? Pictures would help tremendously.
2) Is there a difference between a 1997 Engine Temperature sensor and a 1998 Engine Temperature sensor?
Sensor I bought to replace on the car
Drawing of the Sensor connection that I took out. Located behind Alternator.
Please any help would be useful. Thanks.
P.S. I have noticed her car start to idle higher from time to time on it's own when in park.
