For some context, I am rebuilding a 2016 ST that was modified by the original owner (who died) so I cannot get any references to the modifications he has done to the car. After plugging the battery in and putting the car in acc position, the temperature gauge rises even before starts up. I had already checked a temp sensor on the car and seems like it is in a functional condition.
Just by looking at the engine bay, I can tell that the original owner installed some COBB intake parts and some blow off valve and maybe modified the engine harness because there some connectors that are not connected to anything.
Is there cylinder head temp sensor that is I don't know of, because I am about to give up and send it to a dealer
