high and low temp code

I keeping getting this code. I replaced the coolant tempature sensor and unplugged battery to reset code. Now it still keeps coming up with that code. Does anyone know what the heck to do? I appreciate any help.

Thanks

You did'nt say what code? List the code & someone will help. Intake air temp, coolant temp &
also what motor ? Also with OBD2 you'll need a scan tool to clear the code, don't know about those
code reader toys though.
You have seperate codes for for lets say a coolant sensor low voltage{P0117} as oppposed to a high reading{P0118}. The system has parameters for holding stored codes & iluminating the MIL light & will clear history after 40 warm/cool cycles not seeing a fault by itself.

Sorry it is codes PO117 and PO118 and it is a 2.2L
