My check engine light comes on for low temperature.
I have a 2005 Chevy Venture van. The check engine light comes on and says
the thermostat is bad. I have had thermostat replaced and coolant sensor
replaced. But still has the same problem. I had a local repair shop hook up
there Snap-on diagnostic tool and it showed that the computer was actually
seeing a tempature reading 186 degrees. I'm to the point I do not know what
to try now?
