 Show This displayed on the info center when I was coming him from work a few hours ago. I also noticed that the temp gauge dropped all the way down to cold. Just to be safe I pulled into a parking lot and looked under the hood. The engine didn't feel hot, and I also didn't see any steam or anything, so I started it up and drove the rest of the way home (about 6 or so miles) without anything happening. The gauge dropping down makes me think that a sensor or wire somewhere got loose or is going bad. Can anyone else think of what could be wrong? Impala While undergoing many facelifts in its history, the Impala has proved itself to both civilians and police forces as one of the most capable 4-door cars GM has ever offered. Currently moving towards its 10th generation the Impala is one of the longest lasting and popular models.

Join Date: Dec 2009 Posts: 2 Likes: 0 Received 0 Likes on 0 Posts I have an 06 Impala w/ the 3.5 liter. It gives me the same message in the odometer space: "engine hot / AC off". I know the engine is NOT overheating. The warning light does not come on, heater works fine, no coolant running into overflow, or for that matter, running anywhere. This happened about two months ago for about a day or two and it "self-corrected". The message stopped and the gauge began to work again. If I had to guess, there is a sensor somewhere that has failed, is inoperative, or could be clogged with scale. New water pump & correct % of coolant/water. Anyone have any ideas? CF Beginner

Have you googled "Engine Hot AC Off" and seen the thousands of postings about this issue. Do you think everyone of us have a short in the ECTS circuit? I'm not trying to sound rude but I have this problem with my 2010 Chevrolet Impala and it costs me $80 to have the dealership reset the codes on the dang car. They couldn't find any issues with the car so the fix was to reset the codes. Now...here's the million dollar question...how can the vehicle owner reset the codes without having to pay the dealership $80 a pop? CF Veteran

The "Engine Hot AC Off" warning actually turned off on my long commute home yesterday. Started the car up this morning and the warning signal came back on about a mile down the road and stayed on all the way to work this morning (75 miles). This issue is posted all over the internet on several different types of GM products. CF Beginner
Join Date: Oct 2011 Location: North Carolina Posts: 3 Likes: 0 Received 0 Likes on 0 Posts just happened with my 2010 impala last nite. DIC message warning popped up, gauge flat on "C". Car did not seem to be overheating. Defrost was on to clear windows. Dropped it off at dealer. The owners manual just indicated that this mean coolant hotter than normal and ok ot continue to drive but get checked out soon to prevent compressor damage. Odd the car is running hotter than normal and the concern is on the a/c compressor?? Dealer just called as i wrote this, say diag indicates thermostat needs to be replaced. .. and oh, btw, you are due for tranny fluid mtc and FI cleaning for another 300$. Can't tell me and I don't know by the gauge if the car got hot enough to do damage or not. It is hard for me to believe that with thermostat stuck in open position (he couldn't tell me how it was stuck) that the gauge would not move off C in the 25 miles i drove it (i did not really notice if before the light came on the temp guage was reading or not), so i am not sure what to assume regarding the temperature the engine may have reached. I read that default for the computer is to assume the worst and declare engine is hot, but how is it, the thermostat goes bad and the guage doesn't read more than its coldest at the same time. I guess time will tell. CF Beginner

You can simply understand this phenomenon that when your engine reaches a high temperature, at this time the engine computer system will be aware that there's too much heat or the cooling fan is not operating. To lower the load to avoid further heat gain, AC will be off.
What does engine Hot AC off mean on 2008 Chevy Impala?banzay answered 5 years ago. Temperature coolant sensor you meant. Check the coolant level and check the hoses from the radiator if are hot (just touch and let go). This would show if the thermostat is ok.
What causes Chevy Impala to run hot?The most common reasons a Chevrolet Impala is overheating are a coolant leak (water pump, radiator, hose etc.), the radiator fan, or a failed thermostat.
