I have a 2001 Chevy Monte Carlo. The low coolant sensor is staying on after replacing with a new sensor. Coolant is full. How do you get the sensor light to go off? Tried reseting, will not go off..

The next thing to check would to look for corrosion on the connector that plugs into the sensor. The metal "terminals" in the plastic connector should be shiny and clean. If not see if you can use a small wire brush to clean them. Then you would need to look for a broken wire from the connector to the engine computer.

I too am having the same problem, but on a 2002 Chevy Monte Carlo LS 3.1L V6. However, I must note that within a few months of having the care (bought new) I had the same problem. Had dealer repair so I can only assume that they simply replaced the sensor. I replaced the sensor, but the error continues to trip. I tested voltage to the ECM (car running) and have good voltaqe (10-12V). In an attempt to determine if issue is the sensor, at the sensor, or somewhere else in the circuit I unplugged the sensor and the light went out. I am assuming its the sensor thats causing the problem, so I tried to locate data on how the sensor works electronically, but have been unsuccessful thus far. If anyone has any information on how the sensor works please let me know.
