Answer :
The question pertains to an engineering problem in vehicle diagnostics, focusing on air leaks in the induction system and smoke testing as a method for detecting those leaks.
The question involves diagnosing issues related to automotive induction systems, specifically concerning leaking ductwork and leak detection methods. Technician A suggests that a leak in the ductwork can lead to incorrect diagnostic readings, which is a valid observation since air leaks can alter the air-fuel mixture and cause the engine to run improperly. Meanwhile, Technician B recommends using smoke testing as the preferred method for finding leaks in the induction system. Smoke tests involve injecting smoke into the system and observing where the smoke escapes to identify the location of the leaks. It is a widely used and effective diagnostic tool in the automotive industry for detecting leaks in various systems, including the induction system.
