METHOD AND SYSTEM FOR REDUCTANT INJECTOR DEGRADATION

Various systems and methods for detecting exhaust reductant injector degradation based on an exhaust NOx sensor are disclosed. In one example, degradation of the reductant injector is indicated when an actual NOx sensor output differs from an expected NOx sensor output by more than a threshold amoun...

description	Various systems and methods for detecting exhaust reductant injector degradation based on an exhaust NOx sensor are disclosed. In one example, degradation of the reductant injector is indicated when an actual NOx sensor output differs from an expected NOx sensor output by more than a threshold amount under engine off conditions.
