Question about 1995 Oldsmobile 88
The check engine light comes on after driving a little while. I brought to the mechanic. He tells me that the engine is only getting to 205 degrees with an actual thermostat. The computer is telling him it is running 285 to 305, thus causing the check engine light to come on. he has change the sensor plug that sits high on the engine to no avail. Please advise a solution.
I have ran into a few instances like this in the past. 1. the sensor itself is bad-not the connector. and 2. you have a blown head gasket that is blowing hot cobustion gases directley at the area where the temp sender is.I ran into this same problem on a 350 chev this past spring and was the head gasket. You can take to your machanic and see if he has a tester he can out on the radiator that checks for combustion gases, this would be your for shure check!
