Abstract

An exhaust aftertreatment system includes a first decomposition chamber that receives exhaust and treatment fluid, a first dosing module that includes a first injector that injects the treatment fluid into the first decomposition chamber, and a second decomposition chamber disposed downstream of the first decomposition chamber and that receives the exhaust and the treatment fluid from the first decomposition chamber. The exhaust aftertreatment system further includes a second dosing module that includes a second injector that injects the treatment fluid into the second decomposition chamber and a pressure sensor that generates a pressure signal based on a pressure of the treatment fluid in the second dosing module. The exhaust aftertreatment system further includes a variable resistor selectively switchable between multiple resistances.
