Claim 2:
3. The exhaust gas aftertreatment system of claim 2, further comprising:
a third sensor disposed proximate the first sensor and the second sensor and configured to
measure the parameter in the exhaust gas aftertreatment system;
wherein the at least one controller is further configured to:
alternately receive sensor values from the third sensor for a third predetermined period of time,
determine a difference between a third sensor value received from the third sensor and the calculated sensor value,
if the difference between the third sensor value and the calculated sensor value is greater than or equal to the threshold value, deactivate the third sensor and receive sensor values only from the second sensor, and
if the difference between the second sensor value and the calculated sensor value is greater than or equal to the threshold value, deactivate the second sensor and receive sensor values only from the third sensor.
