Coolant Temp Sensor help...
Been asked a few times on the site but each time seemed to be a bit different of a solution.
So I'll ask in a new thread. I am getting the 'AC Off Due To High Engine Temp' message. Been going on intermitantly for a while now. Well it's permanent now. I can reset the ECU but it will come back after a few miles. I swapped sensors and put a new connector on it. Wires look good. I have tested the sensors (both old and new) and tested power and continuance to the connector. Changed the thermostat with a new one and tested the old one and found it was good anyway. New coolant of course. Dash temp gauge turns off when the issue comes on. So I'm at a total loss. The code comes on immediately upon starting a cold engine or hot engine. Unless I unplug the computer and plug it back in. Then, like I said, I'll get a few miles before it comes back on. Codes are P0116 and P0118. I get a P219A but I suspect it's a result of the hard start and low efficiency brought on by the temp issue. Interesting note, the dash temp gauge shows just a tad warm when I start it after a reset. Weird. |

This curcuit may share info in the computer to another curcuit. Didnt you wreck the car a while back. You may have a pinched harness.

The continuance test shows a full circuit. The electrical diagram shows no sharing on that circuit either.
But if so, how would I chase that down? |

Have you had a Tech 2 or MDI used on the car?

Don't know what those are. I have tested every component.

Just for laughs try leaving the old sensor out & connected to it doesn't get as hot and see if it still does it.. Meaning eliminate a real engine hot possibility.. If it still does it then it has to be an electrical issue and time to get busy there. Fans on when it does this I assume?
