We need to FORCE GM to re-program for free each time the sensor does a glitch or hit a bump with low fluid and not have to pay $200 plus. This was an add in workaround and needs to be addresses again.

There is a program to upgrade the sensor and cable - may be hard to get dealer to do it.

AND the sensor is NOT a low level sensor it is a things are almost CRITICAL level sensor with no user reset.

I would love to see an actual liquid hight sensor for that battery coolent tank.

These days laser may be better that the Ultrasonic Sensor (used in my day )
remember that from playing with a Arduino.
