Technicians Challenged with Aftertreatment Components

Sensors and tolerances pose problems

Equipment technicians working on various technology behind diesel engine aftertreatment systems face diagnostic challenges, according to a report in Fleet Owner, a sibling publication of Construction Equipment and part of Endeavor Business Media.

Manufacturers say the number of sensors and tight tolerances inherent with the engine tech can mislead technicians, causing them to focus on the symptoms rather than the root cause of the aftertreatment malfunction. The variety of fault codes coming off an engine make it difficult to burrow down on the problem.

Training has been lax, according to cited sources, with technicians not fully understanding how the systems work. In addition, ongoing updates make it difficult to stay on top of current technologies.
