Abstract
Methods and systems are provided for diagnosing a high load purge line of a boosted engine system for undesired evaporative emissions. In one example, a method for diagnosing the high load purge line includes drawing vacuum in the high load purge line under natural aspiration conditions and concurrently purging a fuel vapor canister. In this way, the high load purge line may be diagnosed for undesired evaporative emissions without disrupting a canister purge schedule.
