changed my engine coolant sensor out the other day. Had a code. replaced sensor. Went to clear code by disconnecting the battery. It cleared the code, but when i reconnected the battery a new one came up. Advance track icon came on. had code checked for that and it said module calibration. could not clear code. what next?

 

welcome on a board. I don't know even much about this, may be someone ??

 

You may try disconnecting the battery again to reset the system again but you may have to get it calibrated.

 

thanks

 

There are times when the vehicle is driven a while the PCM senses the problem no longer exists and will erase the light.

 

Agreed !!
