When you replaced both, did both codes come back? If so you might have a wiring, or module connector issue. Check the wiring to the sensors, especially in any areas of heat or vibration.

 

If I'm remembering right, one of the modules is located under the passenger seat, and is prone to corrosion from either window leaks, or from road salt covered boots melting inside the cab. Check that if everything else checks out.
