The engine does not overheat. I can reset the code and correct everything by disconnecting the battery with the key in the "on" position for about a minute or so. This was happening every 5 or 6 days of driving. Now it is happening about every other day. Has anyone else experienced this problem? Anyone know the cause and solution? Thanks.

I have had this problem with my 2008 Equinox, which I bought new. I replaced my engine inlet temperature gauge and it worked for two months, then, like a bad dream,
the message appeared again. I had heard about the fact of low quality replacement parts being sold, but wondered if my engine coolant needed changed. The level was not low, but I had never done a flush, think perhaps debris in the coolant had clogged up the gauge's functioning.
I changed coolant by a flush and so far on my third month, the light has not come on.

When the light came on, my engine in fact was not hot and a cooling fan ran in error, thinking the engine was hot.
