The low coolant sensor in a Pontiac Grand Prix is designed to monitor the coolant level in the reservoir and alert the driver if it falls below a safe threshold. If the sensor is faulty or the coolant level is indeed low, it may trigger a warning light on the dashboard. Regularly checking and maintaining the coolant level can help prevent engine overheating and damage. If you experience a persistent warning despite proper coolant levels, the sensor may need inspection or replacement.
Low coolant or a defective sensor
low antifreeze , or faulty coolant sensor .
there is no reset you have replace the low coolant sensor and flush cooling system and use dexcool coolant.
It should be on the tank of the rad just below the fill neck- remove the wiring harness and there is a clip that holds the sensor to the tank- pull it off with a sideways motion and then pull the low coolant sensor straight out.
It's due to the sensor going bad. Should be in the radiator
On the 2002 grand prix there is a sensor in the radiator about 6 inches from the top on the vehicles right side. It works based on electrical conductivity of the coolant. when it becomes dirty (doesn't conduct) or fails it will show low level. Remove the battery (for access) remove a spring clip (holds the sensor in) pull out the sensor and clean or replace. for the purpose of testing, with the sensor out of the radiator, but still plugged in and the key in run (engine off) ground the sensor to the battery. if the dash light goes out, the sensor is good. clean and reinstall.
The low coolant sensor is etiher plugded, broken, or your coolant is actually low. Check the radiator and resivor tank to see if they are full. If they are and the light is on, drain the coolant. Be careful not to break the plastic petcock. The sensor is located next to the battery on the right side of the car. Remove the battery and pull the sensor out. Clean it or replace it. then put everything back together.
On the side of the radiator, by the filler neck? This is the only low coolant sensor I know of. *Ditto here; There is only one for temp and another for coolant level. Each sets off a different warning light on the dash.
a yellow thermometer
Low coolant or bad sensor
thermostat sticking or low oil or low coolant
its a dance party
