Error codes are always

B1234 -sun sensor
B1416- Engine coolant pump

My first thought is to replace the coolant pump, but the A/C works with the error.
The temperature sensors values varies.
If that's the problem, how are they corrected?
Any thought?
thanks

Thanks you just saved me lot of needless expense.
