1. An exhaust gas aftertreatment system comprising:
an exhaust gas conduit comprising a peripheral wall;
a first sensor attached to the peripheral wall of the exhaust gas conduit and configured to measure a parameter in the exhaust gas aftertreatment system,;
a second sensor attached to the peripheral wall of the exhaust gas conduit and configured to measure the parameter in the exhaust gas aftertreatment system, the second sensor disposed proximate the first sensor; and
at least one controller configured to alternately:
receive sensor values from the first sensor for a first predetermined period of time, and
subsequently receive sensor values from the second sensor for a second predetermined period of time,
subsequently receive sensor values from the first sensor for the first predetermined period of time, and
subsequently receive sensor values from the second sensor for the second predetermined period of time.
