My low coolant light came on when i put a new coolant tank in. The coolant wasnt low. So i put the sensor from my old tank in my new one. and the message center still says low colant. There is no codes. and i tried unplugging the battery. Any ideas of what to do?

 

Apparently it could also be a bad temp sensor. If the sensor doesn't read a temp the pcm thinks your low on coolant.
I'd also double check the connector to the sensor and make sure it didn't get cut anywhere.

 

thanks
