Abstract

Testing of temperature sensors (28, 30, 32) in an emission control system, such as in an exhaust system (10) of a diesel engine, serves to condition further component and/or system testing by determining that sufficient sensor cooling has occurred and that no sensor is “stuck within range” using a strategy (50).
