Fault code P261A and P261C

[Val]

Hello,

When I scan the car, the two error codes appear ( P261A and P261C).I changed the auxiliary water pump that pushes the water to the gas cooler and after I delete them, if I start the engine, they appear again. What else do I need to check or change because I don't know what else to do. 

PS: Until I changed the pump, I only had the P260A error and it won't let me delete it. Now, after I changed the pump, the two errors appear and I can delete them, but they appear again after I start the car.

Thank you

If I posted in the wrong place, please forgive me.
