Default "Check Coolant Level"

Message has been appearing every time I start the car yet the reservoir is full to the correct line and coolant temps are fine. Is this a bad sensor?

There is no sensor.

No personal experience or knowledge, just passing this along:

I had the same problem.. Although I would notice that my coolant temps would freak out sometimes also.

There is a sensor in the drivers side head (Near the front) right behind the alternator. The wire for mine was jammed/pinched behind the alternator bracket. I freed the wire, unplugged then re plugged it back into the sensor and have had zero problems ever since.

Just replaced my coolant sensor because the temp gauge pegged zero but no mention of low coolant level for me. The sensor referred to above ^^ is what I replaced and was $31.

Was told it is a bad "heater panel" causing the message. The car is not losing coolant just triggering a bad message. What exactly is a heater panel??????

It's the HVAC (Heating, Ventilation, Air-conditioning Control) panel located directly under the radio and above the ash tray. If the dual zone control head style: it has a **** on each side to adjust the desired temp and a display that show OAT and desired interior temp for each side of car, fan speed, a/c on-off, which vents air is coming from, recirc mode, etc...

Too much information?

Silly me.....Thank you! Just didn't realize that the panel itself can cause a low coolant message to appear. Live and learn.
