Just riding down the road and the warning buzzer sounds for maybe 2-3 seconds and then quits. Oil level is fine; water level is fine. Not redlining. I'm guessing that maybe the sensor wires, connections or maybe a sensor itself is to blame. Anyone else ever had this problem? How is it fixed?

The results of the search I ran frequently referenced a similar problem when making a sharp turn, but mine is truly intermittant and happens driving straight. Doesn't happen every time I drive the car.

 

Any error codes on the ECU??

Could be a loose sensor connector.

 

i had that problem when I had some air bubbles in my cooling system

 

bubbles in the coolant

 

My coolant sensor always goes off randomly. How do you get bubbles out.

Actually it goes off at the same spots on the roads that I drive often. Its really weird, I guess it's just the certian forces that are just right in certian turns.

 

Mine went off on the interstate after I had jsut refilled it. It probably did it about 20 times. My girlfriend who was trying to sleep wasn't too happy...

Anywho, I just bled it.

 

Well, to follow up with the results....the coolant level was actually the culprit. I thought the coolant was OK because I had drained, flushed and refilled the coolant system back in June. That, plus the car was not running hot. Evidently, the bubbles in the system that I thought I had worked out worked themselves through. Added coolant through the upper fill cap and problem solved.

Sometimes we act like noobs even though we aren't! But i did check the coolant and oil senders. They were OK and not loose.
